Bug #6408362

Change-Id: I69c21d9aeeb663aa6244132ce8d598be888886e2

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.

addNameLocked() was failing when namelist count == 0, which was causing
the fonts not to be loaded.

Cleaned up the system font and fallback font list
memory management using smart arrays.

Cleaned up the addition and removal of font records from
the font family lists.  Previously, list insertion was occurring
when the typeface was constructed, which obscured much of the logic.

load_system_fonts() could potentially be called without
a lock held.  To make this problem less likely to happen
again in the future, adopted a naming convention for all
locked methods.

1) fixes a bug where the a custom font can be loaded prior to the
   system fonts being loaded when Skia is first loaded.
2) fixes a bug where the lists for system fonts and fallbacks can be
   corrupted if the font in the configuration file is not present

This should fix bug 5911298

A feature in Android 3.0 allows Bitmaps to be reused when
loading a bitmap of the same dimensions. A documented limitation
is that the only formats supported are jpeg and png, the most common
formats for Android. But if you actually try to do it anyway, you'll end
up causing memory trashing and an eventual strange native crash. It's not
pretty.

This fix puts code in other possible image format decoders (gif, ico, and
bmp) to return false from the onDecode() operation, which will result in
an exception being thrown back to the user code.

If the paint has a text point size that is small (e.g. < 1)
then the results returned from FreeType are not accurate.

When the system locale is changed, skia reloads its fallback fonts
using the best-matching configuration files for both framework and
vendor.

  Skia Merge (revision 3312)

This CL also includes changes made to Android's copy of
Skia in their J release branch.

Skia's serialize methods are not intended for backwards compatibility,
but the browser used it to implement saved pages. As a result the
revision of Skia used for ICS (r1562) is not compatible with the
revision of Skia used in JB (r3000+). This CL attempts to make pages
saved in ICS render in JB while still allowing JB pages to be saved
and displayed.

The original CL was missing a negation in an if statement and
had to be reverted. This CL reapplies the change with the
necessary correction.

This reverts commit aafd212a.
