* Fix race condition in reading the dropped spans number
As any race condition this should be consider an undefined behavior, and a patch release should be done.

* Replace recordingSpan attributes implementation
Instead of an LRU strategy for cap-ing span attributes, comply with the
specification and drop last added. To do this, the attributesmap is
replaced with a slice of attributes.
* Remove attributesmap files
* Refine addition algorithm
Unify duplicated code.
Fix deduplication algorithm.
Fix droppedAttributes to always be returned, even if the span has no
attributes.
* Unify span SetAttributes tests
* Doc fix to attr drop order in changelog
* Test span and snapshot attrs
* fix lint
* Add tests for recordingSpan method defaults
* Comment why pre-allocation is not done
* Correct grammar in recordingSpan allocation comment
* Update sdk/trace/tracer.go

* Do not store TracerProvider fields in span
Instead of keeping a reference to the span's Tracer, and therefore also
it's TracerProvider, and the associated resource and spanLimits just
keep the reference to the Tracer. Refer to the TracerProvider fields
when needed instead.
* Make span refer to the inst lib via the Tracer
Instead of holding a field in the span, refer to the field in the parent
Tracer.
* Change trace options to accept type not pointer
Add benchmark to show allocation improvement.
* Update CONTRIBUTING.md guidelines
* Update all Option iface
* Fix grammar in CONTRIBUTING
* Optimize evictedQueue impl and use
Avoid unnecessary allocations in the recordingSpan by using an
evictedQueue type instead of a pointer to one.
Lazy allocate the evictedQueue queue to prevent unnecessary operations
for spans without any use of the queue.
Document the evictedQueue
* Fix grammar
* Added Benchmarks around events
Also fixed the attribute benchmarks to reflect the # of attributes in the test
* Fix test txt, and too new a version of time

Remove nil check on return from NewTestSpanProcessor as it can never be
nil, addressing #2396. Also, add nil checks for testSpanProcessor
methods to prevent panics.
This is a simple loggin interface to be used interally for the sdk.
Included is an exmaple in `namedtracer` run:
```
cd example/namedtracer
go run . >/dev/null
```
* Empty queued spans when ForceFlush called
Update the implementation of ForceFlush() to first ensure that all spans
which are queued are added to the batch before calling export spans.
Create a small ReadOnlySpan implementation which can be used as a marker
that ForceFlush has been invoked and used to notify when all spans are
ready to be exported.
Fixes#2080.
* Add a changelog entry.
* Update CHANGELOG.md

* Improve test case to verify multiple flushes.
* Refactor code to use enqueue.
* Be more defensive on waiting for queue.
Update the handling of the force flush span so we only wait on the
channel if we were able to enqueue the span to the queue.
* Fix linter.

* Add semconv/v1.7.0 package
Generated from the v1.7.0 release of the specification using the
semconvgen tool manually. This also updates the project to use this
version of the semconv package.
This does not include the prior, and missing, v1.5.0 and v1.6.0 versions
of the semconv package. They are planned to be added in a follow-on PR.
* Update CHANGELOG.md
* Update versions file for 1.0.0 release
* Prepare stable-v1 for version v1.0.0
* Update trace signal status in documentation

* Refactor startSpanInternal into a tracer method
The span creation and configuration process is split across the tracer
Start method and the startSpanInternal function, each living in
different files. This adds confusion when developing. It requires the
developer to remember certain parts of the configuration happen in one
place or the other.
This unifies the creation and configuration of a new span. It makes this
unification by creating a newSpan method on the tracer. This method will
do all the configuration needed for a new span other than setting the
execution task tracker. This remains a part of the Start method to
preserve any existing timing and tracing the already exists.
* Add a non-recording span to the SDK
* Assign returned context from runtime trace task

* Update trace API config creation funcs
Follow our style guide and return the config struct instead of pointers.
* Update changelog with changes

* Make the tracetest.SpanRecorder concurrent safe
The otelgrpc instrumentation in the contrib repository needs a
concurrent safe implementation as the stream testing is done in a
separate goroutine.
* Refactor concurrency tests
* Deprecate oteltest.Harness for removal
* Add changes to changelog
* Alias oteltest.Harness to internaltest
* Update oteltest/tracer_test.go
remove `oteltest` import.

Test the export timeout by waiting indefinitely for the export to
timeout instead of having a second timer, in its own goroutine, timeout.
The algorithm this replaces fails on machines that are slow and the one
meta-timer is given priority to progress over the export timer that is
being testing, resulting in a false-negative test result.
Move the testing of a BatchSpanProcessor export timeout to its own test
function. This removes the bloat this introduces to the other testing
options and allows customization that enable the testing in a
deterministic manner.
This implements specification requirement:
https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/resource/sdk.md#resource-creation
- Changes `resource.NewWithAttributes` to require a schema URL. The old function
is still available as `resource.NewSchemaless`. This is a breaking change.
We want to encourage using schema URL and make it a conscious choice to have a
resource without schema.
- Merge schema URLs acccording to the spec in resource.Merge.
- Several builtin resource detectors now correctly populate the schema URL.

This adds support for schema URL to the Tracer according to the specification:
https://github.com/open-telemetry/opentelemetry-specification/pull/1666
(Link to replaced by the link to the spec after that PR is merged)
For the future: once the proto is updated we will need to populate the
schema_url field in the messages.
* Refactor TraceState
* Update tracecontext propagator to use new TraceState
* Add TraceStateFromKeyValues to oteltest
* Use oteltest to test TraceState
* Replace IsEmpty with Len for TraceState
* Replace ParseTraceState with ParseTraceStateString
* Clean up naming
* Add immutability test for TraceState
* Add changes to changelog
* Fixes
* Document argument type change in changelog
* Address feedback
Remove circularity of TestTraceStateLen.
* Remove TODO from ReadOnlySpan interface
* Remove the Tracer method from the ReadOnlySpan
This is not required by the specification nor the use of this interface.
* Remove IsRecording from the ReadOnlySpan interface
A read-only span value does not need to know if updates to it will be
recorded. It by definition cannot be updated so no point in
communicating if an update would be recorded.
* Document the ReadOnlySpan interface
* Rename messageEvent* to just event*
* Move the SpanSnapshot into its own file
* Update ReadOnlySpan interface with meta info methods
Add the DroppedAttributes, DroppedLinks, DroppedEvents, and
ChildSpanCount methods to the interface to return additional information
about the span not specified by the specification, but that we are
already providing.
* Add SpanStub to the sdk/trace/tracetest pkg
* Redefine ExportSpans of SpanExporter with ReadOnlySpan
* Rename SpanSnapshot to snapshot and purge docs
* Remove Snapshot method from snapshot type
This method is a hold-over from previous version of the ReadOnlySpan
interface is not needed.
* Update CHANGELOG with changes
