Update metric types to not use pointer receivers (#462)
The methods on the `Float64Gauge`, `Int64Gauge`, `Float64Counter`,
`Int64Counter`, `Float64Measure`, and `Int64Measure` `struct`s do not
need to mutate the internal state of the `struct` and can therefore be
defined with value receivers instead. This aligns closer to the function
signatures of each instruments constructor function. Additionally, this
change means calls to these methods do not need an allocation to the
heap.

Resolves #440

Replace span relationship with a potentially remote parent context (#451)
This PR removes the non-compliant ChildOf and FollowsFrom interfaces
and the Relation type, which were inherited from OpenTracing via the
initial prototype. Instead allow adding a span context to the go
context as a remote span context and use a simple algorithm for
figuring out an actual parent of the new span, which was proposed for
the OpenTelemetry specification.

Also add a way to ignore current span and remote span context in go
context, so we can force the tracer to create a new root span - a span
with a new trace ID.

That required some moderate changes in the opentracing bridge - first
reference with ChildOfRef reference type becomes a local parent, the
rest become links. This also fixes links handling in the meantime. The
downside of the approach proposed here is that we can only set the
remote parent when creating a span through the opentracing API.

Allow dropping items from correlations + docs + cleanups (#454)
* Drop entry from correlation map

Entry used to contain stuff like TTL, but right now the notion of
entry was dropped from the spec.

* Compute exact size of the correlations map

The map will be immutable, so spend some more time to ensure that we
will not unnecessarily waste some memory on a basically read-only map.

* Allow dropping keys from correlations map

This is to follow the spec. Before this change it was possible in an
awkward way by using Foreach to gather and filter the key-value pairs,
and then calling NewMap with a MultiKV MapUpdate.

* Document the correlation package

* Add missing license blurbs in correlation package

* Add tests for deleting items in correlations

* Factor out getting map size and test it

This is an implementation detail that can't be tested in a black-box
manner.

* Fix copyright dates

* Simplify/disambiguate keySet function parameters/return values

* Fix typo in Apply docs

* Fix test names

* Explain the nonsense of dropping keys from new map

6b4acf47b8 Reorganize propagation code (shrink PR 381) (#444)
* Rename distributedcontext package to correlation

Correlation is the name we agreed upon.

* Move trace propagators to api/trace

The trace propagators tests had to be moved to a testtrace subpackage
to avoid import cycles between api/trace and internal/trace.

Needed to shut up golint about stutter in trace.TraceContext -
TraceContext is a name of a W3C spec, so this stutter is
expected. It's certainly still better than golint's suggestion of
having trace.Context.

* Rename api/propagators to api/propagation

This package will not contain any propagators in the long run, just
the interface definitions.

2d5ba32f4f Remove Tracer name prefix for Span names (#430)
Spans should not have the Tracer name as a prefix for their names. This
removes the `spanNameWithPrefix` function and instead passes through the
span name unmodified wherever this had been called.

Tests that checked Span names are updated to have the non-prefix
expected names.

91091b44eb Add comments and test for 64-bit field alignment (#418)
* 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.

9a2484c373 Implement support for NonAbsolute Measurement MaxSumCount (#335)
* Add tests for nonabsolute and varying sign values

* Implement support for NonAbsolute Measurement MaxSumCount

Previously, the MaxSumCount aggregator failed to work correctly with
negative numbers (e.g. MeasureKind Alternate()==true).

* Pass NumberKind to MaxSumCount New() function

Allows it to set the initial state (current.max) to the correct value
based on the NumberKind.

* Revert extraneous local change

* Pass full descriptor to msc New()

This is analagous to the DDSketch New() constructor

* 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
