* 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.
* Update SamplingParameters
Remove HasRemoteParent fields from SamplingParameters. The
HasRemoteParent field is a duplicate of the Remote field of the parent
span context contained in the ParentContext.
Change the `ParentContext` field from storing a `SpanContext` to a
`context.Context` that holds the parent span. This is to conform with
the OpenTelemetry specification and resolve#1727.
* Update PR number
* Make SpanContext Immutable
* Adds NewSpanContext() constructor and SpanContextConfig{} struct for
constructing a new SpanContext when all fields are known
* Adds With<field>() methods to SpanContext for deriving a SpanContext
with a single field changed.
* Updates all uses of SpanContext to use the new API

* Address PR feedback
* Fix new uses of SpanContext from main
* Add Tracestate into the SamplingResult struct
Add `trace.Tracestate` field into the SDK `trace.SamplingResult` struct.
Use ParentContext from SamplingParameters to return Tracestate in
`traceIDRatioSampler`, `alwaysOnSampler` and `alwaysOffSampler`.
Add a new test to check that Tracestate is passed.
* Updated CHANGELOG.md for #1432 PR
Added changes description for #1432.
* Update sdk/trace/sampling_test.go

package.

* Rework trace.IDGenerator interface
* NewTraceID() -> NewIDs(ctx)
** Returns both TraceID and SpanID
* NewSpanID() -> NewSpanID(ctx, traceID)
** Returns only SpanID, has access to TraceID
* Both methods now receive a context, from which they may extract
information
* startSpanInternal() updated to receive a context to pass to the ID
generator
* Drop outdated comment from docblock
