* Generalize pthread TLS to any trivial type
Use multiple pthread keys for types larger than a machine word.
Implement generic timer TLS optimization on all platforms.
This PR imports unit tests and end-to-end tests of binder transport from the internal repository. No further changes will be made to internal repository.
Motivation: In debug builds, `DebugOnlyTraceFlag`s are hard-coded to be
disabled. This results in unreachable code paths that the compiler can
detect, which prevent us from enabling `-Wunreachable-code-aggressive`
on the builds.
This work aims to reduce the number of places that switch on
`trace_flag.enabled`.

The iterator returns a newly-constructed `std::pair<absl::string_view, absl::string_view>`.
Compiled with `-Wrange-loop-bind-reference` on iOS due to new dependencies for
iOS tests.

See code commentary for an explanation.
Add an additional constructor to allow `log_linux.cc` to compile with
GPR_PTHREAD_TLS. Without it:

* Implement type safety for TLS
This is mostly free when compiler support is available, but requires
careful templating when implemented using pthread.
Significantly slimmed the tls.h interface; it now only defines the "TLS
keyword" for each supported compiler, delegating enforcement of correct
usage (i.e. must be static) to the compiler itself.
Implemented implicit conversion for the pthread wrapper so it can be
used (mostly) the same as native support. Notable exception to this is
that static_cast<void*> is needed when printing a pointer stored in TLS
as %p.
* Use GPR_THREAD_LOCAL macros consistently
* Buffer HPACK parsing until the end of a header boundary
HTTP2 headers are sent in (potentially) many frames, but all must be
sent sequentially with no traffic intervening.
This was not clear when I wrote the HPACK parser, and still indeed quite
contentious on the HTTP2 mailing lists.
Now that matter is well settled (years ago!) take advantage of the fact
by delaying parsing until all bytes are available.
A future change will leverage this to avoid having to store and verify
partial parse state, completely eliminating indirect calls within the
parser.

Most instances were already explicit through comments, so it's clear
that the author cared about being explicit; use the compiler to ensure
this is always the case.
It is not possible for such a function to be implemented in a way that
is understood by annotalysis. Mark it deprecated and replace instances
of its use with direct mutex/condvar usage.
Add a bunch of missing thread safety annotations while I'm here.
