SkLanguage and SkPaintOptionsAndroid optimization

(1) Global linked list to manage SkLanguage and SkPaintOptionsAndroid
    objects
(2) All copy constructor overheads associated with above classes are
    changed to simple pointer assignment
(3) All string related operations in SkLanguage class are replaced with
    simple pointer manipulation. Also saving on string allocations.
(4) SkLangList and SkPaintOptionsAndroidList are 2 new classes created
    to manage the global linked list
(5) SkLanguages and SkPaintOptionsAndroids are 2 new singleton classes
    created to work with the global linked list class (See 4)

Skia: Add NEON intrinsic D32_A8_Black and D32_A8_Opaque

If NEON support is indiciated via __ARM_HAVE_NEON flag then use
an optimized NEON intrinsics version of the D32_A8_Black and D32_A8_Opaque
masking function.

Skia: Fix special case in D32_A8_Opaque and _Black

Neon optimization implemented for D32_A8_Opaque and D32_A8_Black
is not using the right mask for width>=2 and width<4 case. This
is fixed in this patch by handling 4 different cases: width >=8,
4<=width<7, 2<=width<4, and residual case.

Support for HW JPEG Decoder in SKIA

Add support to use HW JPEG Decoder in SKIA
through dynamic loading of vendor specific
library. Vendor library to provide APIs to
check if HW decode is possible for a stream
and if so decode the stream. Methods
allocPixelRef and getPrefConfig in
SkImageDecoder made public because vendor
lib has access only to the SkImageDecoder
and not its derived class.

Modify sample buffer size for larger displays

BZ: 146848

Increases the intermediate buffer size for sample pixel indexes,
used in the sample proc function calls. If the operation is bigger
than the buffer it's split into multiple calls, creating overhead.
This would especially impact the performance of SIMD optimizations.

SkDraw::drawRect optimization

New class in SkDeviceLooper.cpp falls in in the critical code path of
SkDraw::drawRect().  This new class SkDeviceLooper does nothing except
for bound checking. It copies the modified rect bounds into new pointer
variables and returns them back "if needed". The additional overhead of
creating an object of SkDeviceLooper class and calling member functions
reduces performance.  This patch creates a pre-check condition and if
it succeeds we know for sure SkDeviceLooper won't change the rect
bounds. Under this condition, we avoid using the SkDeviceLooper class.
