More generic configuration system is introduced in order to i) unify the
way how modules access the configurations instead of using low-level
get/setenv functions and ii) enable the customization for where configuration
is stored. This could be extended to support flag, file, etc.
Default configuration system uses environment variables as before so
basically this is expected to work just as it did. This behavior can
change by redefining GPR_GLOBAL_CONFIG_DEFINE_*type* macros.

alignment options (for cache-alignment).
We shrink by:
1) Removing an unnecessary zone pointer.
2) Replacing gpr_mu (40 bytes when using pthread_mutex_t) with
std::atomic_flag.
We also header-inline the fastpath alloc (ie. when not doing a zone
alloc) and move the malloc() for a zone alloc outside of the mutex
critical zone, which allows us to replace the mutex with a spinlock.
We also cache-align created arenas.
BoringSSL builds its crypto_test and ssl_test as single targets, while
gRPC was building them with a target per file. This no longer works with
tip-of-tree BoringSSL.
This change aligns gRPC with the way that BoringSSL builds its tests.
The changes to boringssl/gen_build_yaml.py were done by hand, all other
changes result from generate_projects.sh.
All these changes need to go together to make sense
- changes to use new version of upb in bazel
- allowing includes in build target option
- script for generating c code (upb) for protos
- generated code for example protos
- adding changes for non-bazel builds
- change sanity tests to ignore the generated files.
grpc_handshake is renamed to GrpcHandshake, using C++ class definitions
instead of C-style vtable classes. Update callers to use new interfaces.
We use RefCountedPtr to simplify reference tracking.
