7406b96abc CriticalSection: Use types+methods from base/platform_thread*.*.
Use PlatformThreadRef, CurrentThreadRef and IsThreadRefEqual instead of pthread_t, pthread_self and operator== (or !=).

ed281e9c9b New lock implementation for mac.
According to my measurements, it's about 100x faster than the native mutex implementation in OSX.  Google "OSX mutex performance" for more info.

To ease use of WebRTC in other codebases, update some macros
to match glibc's ansidecl.h, which uses double-underscores for attributes.

Reason for revert:
Broke downstream compile step, possibly relandable when using a MSVC version that has constexpr, other than that I'm out of ideas.

.../webrtc/base/atomicops.h:71:8: note:   no known conversion for argument 1 from '<brace-enclosed initializer list>' to 'const rtc::AtomicInt&'

91d6edef35 Add RTC_ prefix to (D)CHECKs and related macros.
We must remove dependency on Chromium, i.e. we can't use Chromium's base/logging.h. That means we need to define these macros in WebRTC also when doing Chromium builds. And this causes redefinition.

Alternative solutions:
* Check if we already have defined e.g. CHECK, and don't define them in that case. This makes us depend on include order in Chromium, which is not acceptable.
* Don't allow using the macros in WebRTC headers. Error prone since if someone adds it there by mistake it may compile fine, but later break if a header in added or order is changed in Chromium. That will be confusing and hard to enforce.
* Ensure that headers that are included by an embedder don't include our macros. This would require some heavy refactoring to be maintainable and enforcable.
* Changes in Chromium for this is obviously not an option.

fec2c6d7eb Prevent potential double-free if srtp_create fails.
If srtp_create fails while adding streams, it deallocates the session
but doesn't clear the passed pointer which then could lead to a
double-free in the SrtpSession dtor.

The CL also adds locking for libsrtp initialization / shutdown.

494f20977e Move CriticalSection into rtc_base_approved.
This class is being used from both libjingle and webrtc but we recently had a regression when we added dependency on libjingle's Thread class. This cleans that up and moves the implementation of CriticalSection and helper classes into the source file.

I'm also improving debugging facilities and constness.

a32f064e97 Fix build configuration bug with debug builds.
The problem we were running into on the Mac 10.9 debug bot in Chrome turned out to be good ol'fashion memory corruption. Part of webrtc was being compiled with _DEBUG, another half without it. This caused the definition of some symbols to be out of sync (notably pthread_mutex_t) and would cause code built from common.gypi, to overwrite memory allocated via common types from base/base.gypi derived code.  Fun stuff to track down.  This was a problem in particular with base/criticalsection.h since it's inlined into multiple object files but will have different definitions of what a mutex is.

Effectively re-lands r5516 which was reverted because talk/-only
checkouts existed. This now resides in webrtc/base/, so no talk/-only
checkouts should be possible.

This change also enables -Wthread-safety for talk/ and fixes a bug in
talk/media/webrtc/webrtcvideoengine2.cc where a guarded variable was
read without taking the corresponding lock.
