Comment should be complete sentences outside of lists with sentence

* Replace use of old term label with attribute
The specification has unified on the term attribute to describe
key-value pairs. There exist still many hold-overs of the use of the
term label. This updates those uses or deprecates exported types and
functions in favor of renamed forms.

* Added Linux-specific detector for the os.description attribute
* Generalized OS description detector with placeholder function for unimplemented OSes
* Extended osDescription function to *nix OSes based on golang.org/x/sys/unix
* Added WithOS resource configuration function to configure all of the OS resource attributes

* Changelog update
* Fixed wrong function name in documentation header for WithOSDescription
* Updated documentation header for platformOSDescription function
* Renamed restoreProcessAttributesProviders test helper function
The function restoreProcessAttributesProviders was renamed to simply
restoreAttributesProviders to better reflect its broader scope, which
not only applies to process attribute's providers.
* Fixed os_linux.go overriding build tags defined inside the file
The suffix on os_linux.go was overriding the build tags already defined
in that file. The file was renamed to os_release_unix.go, reflecting
the main function defined in the file.
For consistency, os_darwin.go was renamed to os_release_darwing.go, as
its primary purpose is to also define the osRelease function.
* Removed use of discontinued function resource.WithoutBuiltin
* Added PR number to changelog entries
* Updated go.sum files after run of make lint
* Linux implementation: ignore lines with an empty key
* Linux implementation: avoid unquoting strings less than two chars

* Optimized implementation of charsToString
* Safer temporary file deletion with t.TempDir()
* Used t.Cleanup() for safer mocking of runtime providers in OS resource tests
* Handled optionality of DisplayVersion registry key.
For example, CI machine runs on:
Windows Server 2019 Datacenter (1809) [Version 10.0.17763.1999]
So, to not add an extra white space due to missing DisplayVersion,
this value is checked to be not empty, and only in such case a
trailing space is added for that component.
* Workaround to handle the case of DisplayVersion registry key not present
* Excluded unsupported GOOSes by negation of supported ones
* go.sum update after running make

This implements specification requirement:
https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/resource/sdk.md#resource-creation
- Changes `resource.NewWithAttributes` to require a schema URL. The old function
is still available as `resource.NewSchemaless`. This is a breaking change.
We want to encourage using schema URL and make it a conscious choice to have a
resource without schema.
- Merge schema URLs acccording to the spec in resource.Merge.
- Several builtin resource detectors now correctly populate the schema URL.

This includes all of the associated methods, such as
AsUint64, AsUint64Atomic, AsUint64Ptr, CoerceToUint64, SetUint64
SetUint64Atomic, SwapUint64, SwapUint64Atomic, AddUint64,
AddUint64Atomic, CompamreAndSwapUint64, CompareUint64
Only significant change as a result was converting the histogram
aggregator's `count` state field into an int64 from a `metric.Number`.

* Switch MinMaxSumCount to a mutex lock instead of StateLocker
With multiple values being modified for each Update(), a single mutex
lock and non-atomic operations ends up being faster than making each

* Point to the convenience functions in api/key package
This is to increase the visibility of the api/key package through the
api/core package, otherwise developers often tend to miss the api/key
package altogether and write `core.Key(name).TYPE(value)` and complain
at the verbosity of such a construction. The api/key package would
allow them to write `key.TYPE(name, value)`.
* Use the api/key package where applicable
This transforms all the uses of `core.Key(name).TYPE(value)` to
`key.TYPE(name, value)`. This also should help increasing the
visibility of the api/key package for developers reading the otel-go
code.

This PR adds histogram support to the prometheus exporter.
- Adds a new aggregator selector that returns a histogram for `MeasureKind`.
The selector can be constructed using `simple.NewWithHistogramMeasure`
- Adds support for histogram aggregators in prometheus collect method.
With this PR, the default selector is changed to use histograms.
In order to support the prometheus histogram, the `aggregator.Histogram`
interface is extended with the `Sum` method.

the place where we can access the labels, and thus test the label
iterator.
* Bring back the iterator benchmarks
* Simplifications and docs
* Fix copyright to be consistent with the rest

- Add Apache 2.0 header to source files that did not have one.
- Update all existing headers dated to 2019 to be 2020
- Remove comma from License header to comply with the Apache 2.0
guidelines.
* Update Copyright notice
Use the standard Copyright notices outlined by the
[CNCF](https://github.com/cncf/foundation/blob/master/copyright-notices.md#copyright-notices)
The `checkpoint` function is executed in a single thread so we can do
the encoding lazily before passing the encoded version of labels to
the exporter. This is a cheap and quick way to avoid encoding the
labels on every collection interval.

* Add support for Resources in the SDK
Add `Config` types for the push `Controller` and the `SDK`. Included
with this are helper functions to configure the `ErrorHandler` and
`Resource`.
Add a `Resource` to the Meter `Descriptor`. The choice to add the
`Resource` here (instead of say a `Record` or the `Instrument` itself)
was motivated by the definition of the `Descriptor` as the way to
uniquely describe a metric instrument.
Update the push `Controller` and default `SDK` to pass down their configured
`Resource` from instantiation to the metric instruments.
* Update New SDK constructor documentation
* Change NewDescriptor constructor to take opts
Add DescriptorConfig and DescriptorOption to configure the metric
Descriptor with the description, unit, keys, and resource.
Update all function calls to NewDescriptor to use new function
signature.
* Apply suggestions from code review
Co-Authored-By: Rahul Patel <rghetia@yahoo.com>
* Update and add copyright notices
* Update push controller creator func
Pass the configured ErrorHandler for the controller to the SDK.
* Update Resource integration with the SDK
Add back the Resource field to the Descriptor that was moved in the
last merge with master.
Add a resource.Provider interface.
Have the default SDK implement the new resource.Provider interface and
integrate the new interface into the newSync/newAsync workflows. Now, if
the SDK has a Resource defined it will be passed to all Descriptors
created for the instruments it creates.
* Remove nil check for metric SDK config
* Fix and add test for API Options
Add an `Equal` method to the Resource so it can be compared with
github.com/google/go-cmp/cmp.
Add additional test of the API Option unit tests to ensure WithResource
correctly sets a new resource.

* Do not expose a slice of labels in export.Record
This is really an inconvenient implementation detail leak - we may
want to store labels in a different way. Replace it with an iterator -
it does not force us to use slice of key values as a storage in the
long run.
* Add Len to LabelIterator
It may come in handy in several situations, where we don't have access
to export.Labels object, but only to the label iterator.
* Use reflect value label iterator for the fixed labels
* add reset operation to iterator
Makes my life easier when writing a benchmark. Might also be an
alternative to cloning the iterator.
* Add benchmarks for iterators
* Add import comment
* Add clone operation to label iterator
* Move iterator tests to a separate package
* Add tests for cloning iterators
* Pass label iterator to export labels
* Use non-addressable array reflect values
By not using the value created by `reflect.New()`, but rather by
`reflect.ValueOf()`, we get a non-addressable array in the value,
which does not infer an allocation cost when getting an element from
the array.
* Drop zero iterator
This can be substituted by a reflect value iterator that goes over a
value with a zero-sized array.
* Add a simple iterator that implements label iterator
In the long run this will completely replace the LabelIterator
interface.
* Replace reflect value iterator with simple iterator
* Pass label storage to new export labels, not label iterator
* Drop label iterator interface, rename storage iterator to label iterator
* Drop clone operation from iterator
It's a leftover from interface times and now it's pointless - the
iterator is a simple struct, so cloning it is a simple copy.
* Drop Reset from label iterator
The sole existence of Reset was actually for benchmarking convenience.
Now we can just copy the iterator cheaply, so a need for Reset is no
more.
* Drop noop iterator tests
* Move back iterator tests to export package
* Eagerly get the reflect value of ordered labels
So we won't get into problems when several goroutines want to iterate
the same labels at the same time. Not sure if this would be a big
deal, since every goroutine would compute the same reflect.Value, but
concurrent write to the same memory is bad anyway. And it doesn't cost
us any extra allocations anyway.

* Rework number equality
Compare concrete numbers, so we can get actual numbers in the error

also uses InDelta for comparing floats.

* Run observers in fixed order
So the tests can be reproducible - iterating a map made the order of

The `go.opentelemetry.io/otel/exporter/trace/jaeger` package was
mistakenly released with a `v1.0.0` tag instead of `v0.1.0`. This
resulted in all subsequent releases not becoming the default latest,
meaning that `go get`s pulled in the incompatible `v0.1.0` release of
that package when pulling in more recent packages from other otel
packages. Renaming the `exporter` directory to `exporters` fixes this
issue by consequentially renaming the package.
Additionally, this action also renames *all* exporters. This is
understood to be a disruptive action to existing users as they will need
to update any dependencies they currently have on our exporters.
However, it was decided to take this action regardless. The need to
resolve the existing issue explained above is highly important, and
given the Alpha state of this project these kinds of breaking changes
should be expected (though not without reason).

Rename the package from "export" to "metric". Note that all the existing
imports of this package use an explicit name of `export` and, therefore,
no import declaration changes are included.
Rename the `MetricKind` to `Kind` to not stutter in the type usage. Note
this does not include a method name change for the `Descriptor` method
`MetricKind`.
* Add comments on needed filed alignment
Add comment about alignment requirements to all struct fields who's
values are passed to 64-bit atomic operations.
Update any struct's field ordering if one or more of those fields has
alignment requirements to support 64-bit atomic operations.
* Add 64-bit alignment tests
Most `struct` that have field alignment requirements are now statically
validated prior to testing. The only `struct`s not validated that have
these requirements are ones defined in tests themselves where multiple
`TestMain` functions would be needed to test them. Given the fields are
already identified with comments specifying the alignment requirements
and they are in the test themselves, this seems like an OK omission.

based on the NumberKind.
* Revert extraneous local change

* Remember to run make precommit first
* Add tests for empty checkpoint of MaxSumCount aggregator
An empty checkpoint should have Sum() == 0, Count() == 0 and Max()
still equal to the numberKind.Minimum()
* Return ErrEmptyDataSet if no value set by the aggregator
Remove TODO from stdout exporter to ensure that if a maxsumcount or
ddsketch aggregator returns ErrEmptyDataSet from Max(), then the
entire record will be skipped by the exporter.
Added tests to ensure the exporter doesn't send any updates for
EmptyDataSet checkpoints - for both ddsketch and maxsumcount.
* Relayout Aggreggator struct to ensure int64s are 8-byte aligned
On 32-bit architectures, Go only guarantees that primitive
values are aligned to a 4 byte boundary. Atomic operations on 32-bit
machines require 8-byte alignment.
See https://github.com/golang/go/issues/599
* Addressing PR comments
The use of Minimum() for the default uninitialized Maximum value means
that in the unlikely condition that every recorded value for a measure
is equal to the same NumberKind.Minimum(), then the aggregator's Max()
will return ErrEmptyDataSet
