This exposes a bug in clang, reported upstream as
https://bugs.llvm.org/show_bug.cgi?id=51368.
The clang bug is mitigated using a fake scoped lock; that allows the
current code to compile while also serving as a change detector to
prevent it from going stale; if the compiler bug is fixed, the compiler
will see an overlapping locking requirement, and reject this code, which
will prompt a human being to remove this workaround.
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.

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.
* Add isort_code.sh to sanity tests
* Run tools/distrib/isort_code.sh
* Fine tune the import order for relative imports
* Make pylint and project generation happy
* Fix a few corner cases
* Use --check instead of --diff
* The import order impacts test result somehow
* Make isort print diff and check output at the same time
* Let tools/run_tests/python_utils be firstparty library
* Run isort against latest HEAD
This is a fairly low effort migration of the current codebase into a C++ class, instead of free standing C code.
It builds upon #26657 as a necessary first step.
I've tried to minimize any changes to semantics or logic in this change, except where required to get a minimal amount of encapsulation - which is the major aim of this change.
A future change in this series will buffer slices until all HPACK headers are in memory for a stream prior to decoding -- it's important to have an encapsulated API to the parser before doing so however (hence this CL).
The next change after that will be an almost complete rewrite of the parsing functionality -- since we'll have the total set of header bytes, we'll no longer need to support suspending decoding at arbitrary points. This will allow us to move to a simple recursive descent parser, eliminate a bunch of indirection in this code, and end up in a much more malleable place for when we start doing metadata API changes.
(we likely also end up with some good performance wins!)

This code adds an iomgr implementation that's backed by an EventEngine. This uses the EventEngine API alone, and separate work will introduce an EventEngine prototype to plug into it.
See also drfloob#1: @nicolasnoble has a pull request against this branch, implementing the libuv-based EventEngine. One goal here is to implement the iomgr code such that it can be merged independently without affecting normal builds.
This implementation can be built using bazel build --cxxopt='-DGRPC_USE_EVENT_ENGINE' :all
Some shortcuts are being taken to get a working, testable version of the engine. EventEngines are not pluggable, for example.
