* Generating test spans serially should reduce test flakiness
* Update trace export interface
Move to conforming to the specification.
* Update documentation in export trace
* Update sdk trace provider to support new trace exporter

* Fix BatchSpanProcessor.Shutdown to wait until all spans are processed
Currently it exits too soon - before drainQueue is finished
* Check bsp.stopCh to reliably drop span when batcher is stopped
* Enable tests
* Always use WithBlocking

* Name the BSP tests
* Add a drain wait group; use the stop wait group to avoid leaking a goroutine
* Lint & comments
* Fix
* Use defer/recover
* Restore the Add/Done...
* Restore the Add/Done...
* Consolidate select stmts
* Disable the test
* Lint
* Use better recover
* 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)
Change all occurrences of value to pointer receivers
Add meta sys files to .gitignore

- Don't capitalize error statements
- Fix ignored errors
- Fix ambiguous variable naming
- Remove unnecessary type casting

Fix#306
* Add golint to linters and resolve issues.
I decided to remove constructors for some of the propagation types
because the constructors can be reduced to either using the zero value
or a single, non optional member.
* Enable gofmt and commit fixes
* setup sdk exporter package
* use sdk exporter package in sdk trace
* use sdk exporter package in all exporters
* empty the exporters list before testing Load
* move SpanData to the exporter package
* use the SpanProcessor registration, don't register exporters
* rename exporter structs to avoid stutter
* rename Syncer and Batcher to SpanSyncer and SpanBatcher
So it's explicit they are for spans, and we reduce the risk of name
conflict
* remove not moot todo
* rename sdk exporter to export
* only execute the SpanData if it is sampled
* add batch span processor.
* add blocking support.
* use With* function for options.
- also changed how Shutdown is handled.
* block Shutdown until queue is flushed.
* fix comment.
