* Remove Vendor constants from tracing plugins
Unused. And confusing, since "ot" may mean "opentracing" as well.
* Simplify current span key declaration
No need for a block.
* Fix typo

* 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.

* Generate and build before linting
Generated files may require some formatting that happens during
linting. Also missing generated files may result in linter failures.
Building can shake out any syntax/semantic errors and report them in a
much nicer way than the linter does. Which is exactly the reason the
build was running before linters before the Makefile simplification.
* Make stringer tool a dep of generate target, not lint
Lint target does not use the stringer utility - it is being used by go
generate.
* Switch stdout exporter to use ungrouped batcher
* Add unspecified keys to name without equals signs
* Fix tests for stdout exporter
* Add test for unspecified keys
* Move test to stdout_test.go
* histogram aggregator draft
* add tests for buckets
* naming stuffs
* docs
* add tests for buckets
* fix doc
* update year
* adds docs for Histogram
* docs for boundaries.
* addresses review comments
Change to less-than buckets. Add offset checks. Unexport fields that don't need to be exported. Fix tests when running on profile with int64 number kind.
* sort boundaries
* remove testing field
* fixes import order
* remove print 🙈
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`.
This import package doesn't match the tests file, preventing imports of
the project from master with tests (without go modules).
The package path matches the test file version, so this moves
aggregator.go to match too.
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.
- Simplify conditionals.
- Remove unnecessary nil check.
Go type assertions return a bool value indicating whether the
assertion succeeded. When the assertion is performed on a nil value,
the bool becomes false without a panic, therefore the nil check is
unnecessary.
* 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.

* Add inspectable test tracer
This adds a test Tracer implementation that tracks its active and ended
spans and uses a Span implementation that can be inspected (e.g., to see
what attributes have been set).
