6351640285 Fixes for SkRWBuffer
Do not call SkBufferHead::validate in SkROBuffer's destructor, which
may be called in a separate thread from SkRWBuffer::append. validate()
reads SkBufferBlock::fUsed, and append() writes to it, resulting in
a data race.

Update some comments to be more clear about how it is safe to use
these classes across threads.

Test the readers in separate threads.

In addition, make sure it is safe to create a reader even when no
data has been appended. Add tests for this case.

Mark a parameter to SkBufferHead::validate() as const, reflecting
its use.

a3760992c9 Revert of Fixes for SkRWBuffer (patchset #5 id:80001 of https://codereview.chromium.org/1871953002/ )
Reason for revert:
Making MSAN and TSAN rather unhappy.

5b6db07fb5 SkRWBuffer for thread-safe 'stream' sharing
WIP
- Can accumulate (write) data in one thread, and share snapshots of it in other threads
  ... e.g. network accumulates image data, and periodically we want to decode/draw it
- If this sort of thing sticks, should we promote SkData to have the same generality as
  SkRBuffer?

87f3ba4847 Simplify skiatest framework.
skiatest::Test class is now a simple struct.  Some
functionalty, such as counting errors or timing is now
handled elsewhere.

skiatest:Reporter is now a simpler abstract class.  The two
implementations handle test errors.

DM and pathops_unittest updated.

8b0e8ac5f5 Refactor read and write buffers.
Eliminates SkFlattenable{Read,Write}Buffer, promoting SkOrdered{Read,Write}Buffer
a step each in the hierarchy.

What used to be this:

SkFlattenableWriteBuffer -> SkOrderedWriteBuffer
SkFlattenableReadBuffer  -> SkOrderedReadBuffer
SkFlattenableReadBuffer  -> SkValidatingReadBuffer

is now

SkWriteBuffer
SkReadBuffer -> SkValidatingReadBuffer

Benefits:
  - code is simpler, names are less wordy
  - the generic SkFlattenableFooBuffer code in SkPaint was incorrect; removed
  - write buffers are completely devirtualized, important for record speed

This refactoring was mostly mechanical.  You aren't going to find anything
interesting in files with less than 10 lines changed.

This macro replaces:

    reporter->reportFailed(str);
with the shorter code:
    REPORTF(reporter, ("Foo test Expected %d got %d", x, y));

The new form also appends __FILE__:__LINE__ to the message before calling reportFailed().

05af1afd42 eliminate all warnings in non-thirdparty code on mac
Most of these issues were due to functions whose definitions appear in header files; I changed those functions to be 'static inline' instead of just 'static' or 'inline', which kills the warning for such functions.

Other functions that were static or anonymous-namespaced but were unused in cpp files were probably called at some point but are no longer; someone who knows more than I do should probably scrub all the functions I either deleted or #if 0'ed out and make sure that the right thing is happening here.

Lots of unused variables removed, and one nasty const issue handled.

There remains a single warning in thirdparty/externals/cityhash/src/city.cc on line 146 related to a signed/unsigned mismatch.  I don't know if we have control over this library so I didn't fix this one, but perhaps someone could do something about that one.

Fix these class of warnings:
- unused functions

- sign mismatch
- missing function prototypes
- missing newline at end of file
- 64 to 32 bit truncation

The changes prefer to link in dead code in the debug build
with 'if (false)' than to comment it out, but trivial cases
are commented out or sometimes deleted if it appears to be
a copy/paste error.
