* Do not put span context into go context if extraction failed
This causes problems if multiple trace propagators are chained,
because the first propagator in chain may extract a valid span
context, then next propagator will overwrite it with an empty span
context when required headers in supplier are missing.
* Test for clobbering propagators

* 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.

Update license header to standard format for source files missed prior.
Add license header to new source files.
Add Makefile check to test all `*.go` and `*.sh` files have a copyright
notice (or comment about them being auto-generated) within the first few
lines.
* Add skeleton uniqueness checker
* Fix the build w/ new code in place
* Add sync tests
* More test
* Implement global uniqueness checking
* Set the library name
* Ensure ordered global initialization
* Use proper require statement for errors
* Comment
* Apply feedback fixes
* Comment and rename from feedback
* Temporarily opt-out export.Labels from label encoding stuff
* Stop passing label encoding stuff to export.Labels
* Drop label encoding stuff from SDK
* Dogstatd exporter does not need to implement label exporter anymore
* more dogstatd exporter fixes
* export labels get back to encoding stuff
in a lame way, but improvements are coming in following commits
* Get encoded labels through export.Labels
* make SDK to provide its own implementation of export.Labels
* drop dead code
* add noop label exporter
* make export simple labels immutable
* Move the default label encoder to export package
* Simplify the simple export labels a bit
* Reserve some label exporter IDs
* Document and shuffle the code a bit
* Prepare for bring the iterator benchmark test back
We can install a callback to the Batcher's process function - this is
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
* Fix typo
* Put reserved label encoder IDs into constants
We get fewer comments about magic numbers that way.
* Fix the label encoder as label exporter thinko
* Update License header for all source files
- 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)
* 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.
* Move the resource.Provider interface to the API package
Move the interface to where it is used.
Fix spelling.
* Remove errant line
* Remove nil checks for the push controller config
* Fix check SDK implements Resourcer
* Apply suggestions from code review
