fix race: this kCacheSize is probably not meant to be static

TSAN sees us racing to intialize the static const kCacheSize.

This static const value depends on the runtime value image->getSize(), so there
is a race to set it.  I think this is unintentionally copy-paste from the other
tests that use a constant kCacheSize.  It's weird to intialize a constant based
on the first call to test_internal_purge(), though luckily we're always calling
it with same sized images today.

See these TSAN failures:

Insert an empty image when we cannot decode

In SKP deserialization, if there is a 0 byte encoded image, we insert
an empty image into the output SkPicture so that we can continue
deserializing. Do the same when our decoder cannot decode it. This may
be the result of a bug in our decoder, or in the stream serialization.
But it should not mean the entire stream is invalid.

NEON f32 <-> f16 and f32 <-> u16

Adds f32 <-> f16 ARMv7 and ARMv8 NEON code.
Also adds NEON f32 <-> u16 code to make the comparison fair.

The NDK GCC does not support the ARMv8 NEON intrinsics needed to go fastest, so we use a tiny amount of inline assembly.

The ARMv7 half -> float is different enough from the SSE version that it does not make sense to use SkNx.

Still TODO:
ARMv7 float -> half.  Naively translating the SSE version results in 0x0000 where we'd expect a denormal output.

Remove position from FrontBufferedStream

When FrontBufferedStream was written, it implemented getPosition()
and returned true for hasPosition(). The CL that introduced it
(crrev.com/23717055) does not have any indication why, but I'm guessing
it was because it was easy to implement. None of our decoders rely on
this (only some tests do).

Now that we have a decoder (SkRawCodec) that expects to be able to seek
a stream if it has a position (which makes sense - SkStream.h
associates that with SkStreamSeekable, and there is no other way to
check to see if a stream is seekable), it is failing because
FrontBufferedStream reports it has a position and the decoder tries to
seek.

Remove FrontBufferedStream::hasPosition() (reverting to the default,
false) and ::getPosition() (so it will return 0).

Fix tests - do not call FrontBufferedStream::getPosition()

Update CodexTest to test using an FrontBufferedStream, like Android
does.

Add request cache to SkFontHost_fontconfig.

The current code deduplicates SkTypeface instances as all font lookups
should for better use of the glyph cache. This adds a request cache as
well, so that repeated recent requests will return the cached result
instead of doing a full lookup.

Make SkPicture/SkImageGenerator default to SkCodec

Remove reference to SkImageDecoder from SkPicture. Make the default
InstallPixelRefProc passed to CreateFromStream use
SkImageGenerator::NewFromEncoded instead.

Make SkImageGenerator::NewFromEncoded create an SkCodecImageGenerator.
Remove the old version that used SkImageDecoder.

Remove all versions of lazy_decode_bitmap/LazyDecodeBitmap. The default
now behaves lazily.

Update all clients to use the default.

Move SkImageDecoderGenerator into KtxTest.cpp, and use it directly.

This is a rebased version of:
