3b0c30e93c Assert in ~SkMutex that the mutex is unowned.
Destroying a mutex while it is held is never valid, and can be extremely
hard to debug.

033da99803 mark SkAutoMutexExclusive unmovable
The automatic copy and move constructors and such are not appropriate
for this type.  It could be refactored to be movable but not copyable,
but as written it's neither.

9c71e7be10 Remove all global mutexes
Remove the SkBaseMutex (and SkBaseSemaphore). This allows all the thread

9b86955c65 Add thread safety annotations for SkMutex
Introduce SkAutoMutexExclusive for SkMutex RAII.

Unsubclass SkMutex from SkBaseMutex to allow annotations
for class field mutexes separate from global mutexes.

Leave SkAutoMutexAcquire for handling global mutexes using
SkBaseMutex.

Test using GrSingleOwner.h.

c0bd9f9fe5 rewrite includes to not need so much -Ifoo
Current strategy: everything from the top

Things to look at first are the manual changes:

   - added tools/rewrite_includes.py
   - removed -Idirectives from BUILD.gn
   - various compile.sh simplifications
   - tweak tools/embed_resources.py
   - update gn/find_headers.py to write paths from the top
   - update gn/gn_to_bp.py SkUserConfig.h layout
     so that #include "include/config/SkUserConfig.h" always
     gets the header we want.

3b7658a475 Teach TSAN directly about semaphore_t.
Instead of teaching TSAN than SkMutex is a lock to get around it not
understanding Mach semaphore_t routines, teach it that there is a
happens-before relationship between semaphore_signal() and
semaphore_wait().

This reverts commit e395bf2d18.
New changes are entirely restricted to SkSemaphore.cpp.

e395bf2d18 Mac TSAN support: annotate Sk[Base]Mutex as a mutex.
TSAN does not intercept Mach semaphore_t calls used to implement
SkBaseMutex's fSemaphore (its OSSemaphore field).  We can teach
it that Sk[Base]Mutex is a mutex anyway with the same annotations
we use for SkSharedMutex.

This is purely for convenience, to not need to write the lock type
in the guard anymore.  This should all inline away.

   - fuse SkMutex and SkBaseMutex

d9f5d20f81 Revert of Modernize SkMutex and SkSemaphore. (patchset #2 id:20001 of https://codereview.chromium.org/1947153002/ )
Reason for revert:
This CL seems to have broken the Linux x64 and Mac
bots, e.g.

https://build.chromium.org/p/chromium/builders/Linux%20x64/builds/19052
https://build.chromium.org/p/chromium/builders/Mac/builds/15151

The error appears to have something to do with new static initializers being
added.
