Simplify grpc_event into something that can be non-heap allocated.
Deprecate grpc_event_finish.
Remove grpc_op_error - use an int as this is more idiomatic C style.

Remove gcc 4.5 testing and keep 4.4

adding php to cloud to prod tests.

Deliver data up from tcp immediately

Fixed typo

25ns overhead latency timers

Another round of win32 fixes and documentation.

Let's be really pedantic about the status of our submodules.

correct win32-related API usage

-) Fixed a few more (much more rare) race conditions on shutdown.
-) Fixed a degenerate case if we create a server but never start it.

Various Win32 fixes.

Fixing a very edge case where the tcp_client can crash due to race conditions on connection abortion.

-) tcp client and server should no longer starve waiting on orphans
-) proper server shutdown sequence to prevent use-after-free.

By the standard, std::function can only capture class functions, and not
class methods. For some reasons, this works under gcc however. Visual
Studio rejects it. std::mem_fn is proper template to use.

Fix parallel make + MINGW32 dependencies.

Add rdtsc profiling support, implement begin/end and tag hiding

This change fixes a parallel make which always failed with "cannot find
-lprotobuf".

For C++ static libraries, protobuf was already added as dependency, see
commit 5383062d.

Add google root cert to grpc/php docker image

fix: trace for grpc_call_start_batch only displayed lower 32bits of tag
