1771cbf43d posix: Avoid static initializers in static/global mutexes 
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.

Running: 'bench -repeat 10 -match mutex' on an Android device or
a 2.4GHz Xeon Linux desktop shows the following improvements:

                      Before     After

        Galaxy Nexus    1.64      1.45
        Nexus S         1.47      1.16
        Xoom            1.86      1.66
        Xeon            0.36      0.31

This removes 5 static mutex initializers from the library

fde6b414d9 Cleanup of SkPath code to remove SK_OLD_EMPTY_PATH_BEHAVIOR and other 
dead code. The patch also renames kAfterClose_SegmentState for the
SkPath::Iter class, to kEmptyContour_SegmentState which more
accurately reflects the meaning of the state. The Iter can be in that
state initially, before anything has been seen, let alone a close.

20ad5ac8f6 Change download-baselines script to download images from skia-autogen SVN repo 
I have copied the old version (which downloads the images from the buildbots
directly, but only works with our Mac buildbots) to download-baselines-old,
so we can use either version during a transition period.

Another difference: the new version sets the mimetype property of all image
files in the baseline_subdir, even those that have not changed.
