* Remove SDK from othttp instrumentation
* Remove dependency on SDK in api/kv pkg
Benchmark the kv package not the SDK here.
* Update api/global benchmarks
Move SDK related tests to SDK where applicable
* Add internal testing SDK implementation
To be used by the API for testing so it does not depend on the actual
SDK.

* Fix lint on sdk/metric benchmark
* Lint internal/sdk
* Merge internal/sdk into api/trace/testtrace
* Update Changelog
* Make the stdout exporter its own package
Follow the pattern of the other exporters.

Remove unused stdout exporter.
* Remove tests in API that depend on stdout exporter
The global package does not need to be validated with the SDK. A more
properly constructed end-to-end integration test should be built if this
is actually needed.

It is a registered global, access it that way.

* Update docs
* Update example to be for whole package
* Update metric output
Closer match the span output.
* Clean up span output
Print as a batch and cleanup marshaling.
* Correct spelling error in doc

* Support instrumentation library in metrics
* Update stdout exporter to display instrumentation info
* Fix tests that use the STDOUT exporter
* Refactor to keep SDK out of API
* Update global Meter and test Meter version
* Revert unneeded import syntax change
* Fix Unit comment
* Update comments
* Update comment
* Revert no-op change to import
On slower VMs (like the CI VMs), this test was timing out in 2ms and
failing. Additionally, in the process of failing, the suite tear-down
function would reset the globalHandler and cause a race with the spawned
goroutine that was abandoned.
This increases the pause from 2ms to 10ms, unifies and simplifies the
wait logic, and stops the child goroutine on failure.
* Update Tracer API with instrumentation version
Add option to the `Provider.Tracer` method to specify the
instrumentation version.
Update the global, noop, opentracing bridge, and default SDK
implementations.
This does not propagate the instrumentation library version to the
exported span. That is left for a follow-on PR.
* Revert trace_test.go
This is for the next PR.
* Update SDK to include version for default instrumentation
If the instrumentation library name is empty and the default
instrumentation is uses, include the SDK version.
* Update comments and documentation
* Remove default instrumentation version
* Remove the push controller named Meter map
* Checkpoint
* Remove Provider impls
* Add a test
* Expose Provider() getter instead of implementing the interface

* 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

- 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.

[CNCF](https://github.com/cncf/foundation/blob/master/copyright-notices.md#copyright-notices)

* recycle unused recorders in observers
if a recorder for a labelset is unused for a second collection cycle
in a row, drop it
* unregister
* thread-safe set callback
* Fix docs
* Revert "wip: aggregators and selectors"
This reverts commit 37b7d05aed5dc90f6d5593325b6eb77494e21736.
* update selector
* tests
* Rework number equality
Compare concrete numbers, so we can get actual numbers in the error
message when they are not equal, not some uint64 representation. This
also uses InDelta for comparing floats.
* Ensure that Observers are registered in the same order
* Run observers in fixed order
So the tests can be reproducible - iterating a map made the order of
measurements random.
* Ensure the proper alignment of the delegates
This wasn't checked at all. After adding the checks, the test-386
failed.
* Small tweaks to the global meter test
* Ensure proper alignment of the callback pointer
test-386 was complaining about it
* update docs
* update a TODO
* address review issues
* drop SetCallback
