Relates to #1467
* Move metric-related public API out of otel/ pkg
Move GetMeterProvider, Meter and SetMeterProvider to new package
otel/metric/global in the otel/metric module.
This will allow otel/ module to be released as v1.0.

* Rework proto generation
The changes here are:
- Fix the default goal (using "default" target is not doing it).
- Bail out with a useful message if proto submodule is not checked
out.
- Replace the use of docker image with downloading the protoc binary
and building the gogofast plugin ourselves. This gives us a greater
control over the invocation of protoc.
- Use rsync to copy the generated code, instead of pax. Pax did not
work for me (it was complaining about the unknown -0 flag).
The control over the protoc invocation will be useful later, when we
will want to generate a code with data structures in one place and the
collector code elsewhere. The collector code may or may not depend on
gRPC, but data structures have no need for it. This split will happen
when we move the gRPC code out of the OTLP exporter module into a
submodule.
Getting rid of docker has the upside that the generated files do not
belong to root, so there is no hassle of changing the ownership of the
files, and it is not requires to use sudo for the `clean` target. And
not using docker is faster.
The downside of this work is that it depends on more tools: rsync,
unzip and wget. I can only hope that macOS users have those tools too,
and that those tools are invoked the same.

* Baggage API unit tests
* Rename and add unit test
* Update unit test value checking
* Update TODO with issue tracking work.
* Rename *Provider names
There is overlap in naming with MeterProviders and TracerProviders. This
is means the specification is not implemented and these types can not
exist in the same package (#1179). This makes each type and related
functions and types explicit.
* Add changes to CHANGELOG
* Unexport NoopXXX trace types
The change unexports the noop implementations and provide the NoopProvider function for user to construct noop providers. Users can access noop tracer and noop spans by using the provider.
This change removes the types users should never be directly using from the package. It improves the usability of the API by reducing the API surface to half and helping the user to focus on the canonical APIs.

When during determining a parent for a new span, we find out that
there is a current span in the context, we are putting a remote span
context into links as an ignored on demand. A problem with this
approach is that the remote span context will end up in links of every
descendant span. Another problem is that jaeger exporter currently
treats all links as span contexts with a "child of" relationship and
that likely confuses the jaeger visualization.
Tracer.WithSpan() will now accept StartOptions as a variadic final parameter `opts`
that will be passed to the Tracer.Start() invocation that creates the Span
wrapping the user-provided function.
This PR removes the non-compliant ChildOf and FollowsFrom interfaces
and the Relation type, which were inherited from OpenTracing via the
initial prototype. Instead allow adding a span context to the go
context as a remote span context and use a simple algorithm for
figuring out an actual parent of the new span, which was proposed for
the OpenTelemetry specification.
Also add a way to ignore current span and remote span context in go
context, so we can force the tracer to create a new root span - a span
with a new trace ID.
That required some moderate changes in the opentracing bridge - first
reference with ChildOfRef reference type becomes a local parent, the
rest become links. This also fixes links handling in the meantime. The
downside of the approach proposed here is that we can only set the
remote parent when creating a span through the opentracing API.

* Add comments on needed filed alignment
Add comment about alignment requirements to all struct fields who's
values are passed to 64-bit atomic operations.
Update any struct's field ordering if one or more of those fields has
alignment requirements to support 64-bit atomic operations.
* Add 64-bit alignment tests
Most `struct` that have field alignment requirements are now statically
validated prior to testing. The only `struct`s not validated that have
these requirements are ones defined in tests themselves where multiple
`TestMain` functions would be needed to test them. Given the fields are
already identified with comments specifying the alignment requirements
and they are in the test themselves, this seems like an OK omission.

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
Since these methods are about the span itself rather than specifically
*events* on the span, it makes sense to drop "events" from their names.

* rename finish -> end

* change end back to finish for the bridge span in the openTracing bridge

Adding event with timestamp is not yet a part of the OpenTelemetry
specification, but this function will come in handy when implementing
the OpenTracing bridge.
* Add opentracing bridge, wrapper tracer and migration interfaces

context propagation will only work between two OpenTracing bridges.
