* 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).
* Ensure test tracer can start spans concurrently
* Flip conditional logic to return early
* Remove duplicate test
* Fix file name casing
🤦
* Add comments to testtrace code
* Remove Link and AddLink methods from test Span
* Enable concurrently setting and getting test attrs
* Remove SetAttribute from test tracer
* Fix test
* Fix names post-rebase
* Make span start/end configuration more greppable
Rename SpanOption to StartOption
Rename StartOptions to StartConfig
Rename EndOptions to EndConfig
fixes#197
* Merge propagation
Rename and merge propagation and api/propagation
to api/propagators.
Drop propagator suffix in general such that
TextFormatPropagator becomes TextFormat since
usage is propagators.TextFormat
fixes#311
* Rebase and godoc updates
* Revert go mod changes
* Replace carrier with supplier in godoc
* Simplify Makefile
In particular, this change:
* Ensures that the race checker is always used for all tests
* Removes redundant commands
* Splits out `generate` and `lint` as their own commands
* Renames the `circle-ci` command to the more generic `ci`
* Use GOTEST_WITH_COVERAGE instead of old name
* Fix test-with-coverage command
* Fix test-386 command
* Add Min() interface - rename MaxSumCount to MinMaxSumCount
Fixes https://github.com/open-telemetry/opentelemetry-go/issues/319
* update stdout exporter to collect and output the minimum value
* update min and max atomically in Aggregator Update
* changed all references to maxsumcount to minmaxsumcount
* Address PR comments
* Remove AddLink & Link from Span Interface
I have remove AddLink and Link from the interface and all it refereneces and replaced AddLink with addlink, Also Removed respective unit tests

* update with upstream
* 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

get_main_pkgs.sh uses 'mapfile' which is not available in Bash
versions earlier than 4.x. On machines where the default installed
bash is 3.x (OSX), this causes `make precommit` to break.
However, it's easy enough to install a recent version of
bash (e.g. via homebrew) in `/usr/local/bin/bash`. With
`/usr/local/bin` in your path, and `/usr/bin/env bash` as the shebang
line, this enables `make precommit` to pass with flying colors.
