Cleanup pixel ref mutexes in Skia
Mutexes in pixelrefs were done very sloppily initially. The code (a) assumes all
pixelref subclasses want a mutex to guard their lock/unlock virtuals, and (b)
most subclasses use the same mutex for *all* of their instances, even when there
is no explicit need to guard modifying one instances with another.
When we try drawing bitmaps from multiple threads, we are seeing a lot of slow-
down from these mutexes. This CL has two changes to try to speed things up.
1. Add setPreLocked(), for pixelrefs who never need the onLockPixels
virtual to be called. This speeds up those subclasses in multithreaded environs
as it avoids the mutex lock all together (e.g. SkMallocPixelRef).
2. Add setMutex() to allow a subclass to change the mutex choice. ashmem wants
this, since its unflattening constructor cannot pass down the null, it needs
to cleanup afterwards.

Check for pixels allocation failure
Standard memory allocator in Skia abort when an allocation request
fails. However, when allocating in managed heap, need to check for
allocation failure in allocPixels(). This add checks for all allocPixels
calls in Skia Bitmap code.

extend copyTo to support index8 -> index8 deep copies
Now copyTo always supports copying to the same dst config as the src, even
if it could not normally "render" into that config (e.g. Index8).
Part of this change also added a copy-constructor to SkColorTable.
Also removed some trailing ws
