This patch removes static initializers related to static and
global mutexes from the final library's machine code when
building on a pthread-capable system.
We use PTHREAD_MUTEX_INITIALIZER to perform POD-style
initialization. You need a line like the following to declare
a global mutex with it:
SkBaseMutex gMutex = { PTHREAD_MUTEX_INITIALIZER };
We introduce the SK_DECLARE_STATIC_MUTEX and SK_DECLARE_GLOBAL_MUTEX
macros to be able to declare static/global mutexes in the source tree
uniformly.
SkMutex is now defined as a sub-class of SkBaseMutex, with standard
construction/destruction semantics. This is useful if the mutex
object is a member of another C++ class, or allocated dynamically.
We also modify a few places to refer to SkBaseMutex instead of a
SkMutex, where it makes sense. Generally speaking, client code
should hold and use pointers to SkBaseMutex whenever they can
now.
We defined a new built-time macro named SK_USE_POSIX_THREADS
to indicate that we're using a pthread-based SkThread.h
interface. The macro will also be used in future patches
to implement other helper thread synchronization classes.
Finally, we inline the acquire() and release() functions in the
case of Posix to improve performance a bit.

The fuzzer gets my vote as best test tool ever.
There are several issues outstanding: crashes in FixedPoint and a crash in the
path filling code that is most likely due to clipping problems (but maybe not).

correct results for all stroke and fill modes even on the various types
of degenerate paths.
The goals of this patch include:
1. Have Skia store all of the verbs implied by path construction methods, even
if those define degenerate paths. The SVG implementation in WebKit, which is
backed by Skia, needs to know about all elements of the path, even degenerate
ones, for the correct drawing of markers and line caps. For example, in SVG you
should be able to draw a scatter plot by specifying a marker for vertices and
then giving a sequence of moveTo commands. Skia will not store the moveTos,
requiring a different storage mechanism.
2. Assuming 1, maintain the current Skia behavior. That is, make Skia robust to
degenerate paths.
3. Fix an existing bug in Skia where a degenerate moveTo-lineTo pair spits out
warnings from rasterization and produces incorrect results in inverse-fill
renderings.
4. Adds extensive testing for degenerate paths and path rendering in general.
To meet these goals, the patch I am proposing will result in minor additional
storage for degenerate paths (a few bytes per degenerate path, only if the user
defines such paths). There is also some additional overhead in the iteration
code, with the path now cleaned to remove degenerate segments as part of the
iteration process. I suspect this will also fix issues with computing normal
vectors to degenerate segments. Benchmarking suggests that this change may
result in slightly (< 1%) slower path drawing due to the checks for
degeneracy. This overhead could be removed (in fact, a significant speedup
could occur) if the results of iterating to clean up the path were cached.
This would cost memory, of course, and quite a bit of it.
