* Add folder for bindertransport and its smoke test
We will import the sources in the next few pull requests. Main purpose
of this commit is to create the folder and add dummy smoke test to make
sure nothing breaks
* regenerate projects.
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 adds support for protobuf ObjC support for using the proto package to
define the prefix for the file
(https://github.com/protocolbuffers/protobuf/pull/8760).
Once protobuf cuts a release, it likely makes sense to support the same
generator options that the objc generator does, but for now the environment
variable support can used to enable this when building from recent sources.
Eliminate HPACK table
Use a switch statement instead of a table lookup for the first byte of
HPACK parsing.
This will lead the way to some other improvements down the track (I have
a substantial overhaul here planned), but this is a necessary first
step.
* Use constexpr to simplify HPACK parser
This is a bit of a trial balloon: in C++11, generate at load time a
table that used to be hard coded. In C++14, generate that same table at
compile time, but eliminate the code generator.
Should this work out, I'd like to expand the technique so that we can
eliminate some of the confusing tables in this file by keeping the code
that generates them *in the same place* as the code that consumes them.
