f24f2247c2 Add SkCodec, including PNG implementation. 
DM:
Add a flag to use SkCodec instead of SkImageDecoder.

SkCodec:
Base class for codecs, allowing creation from an SkStream or an SkData.
An SkCodec, on creation, knows properties of the data like its width and height. Further calls can be used to generate the image.
TODO: Add scanline iterator

SkPngCodec:
New decoder for png. Wraps libpng. The code has been repurposed from SkImageDecoder_libpng.
TODO: Handle other destination colortypes
TODO: Substitute the transpose color
TODO: Allow silencing warnings
TODO: Use RGB instead of filler?
TODO: sRGB

SkSwizzler:
Simplified version of SkScaledSampler. Unlike the sampler, this object does no sampling.
TODO: Implement other swizzles.

Requires a gclient sync to pull down libpng.

3da9181cd5 On windows, build zlib as a static library. 
Partially in preparation for building libpng on Windows.

Also, this makes us consistent across platforms for PDF.

Uses the version of zlib checked into the Chromium tree.

Remove miniz, which is replaced by zlib.

e6cf9cb685 miniz support in SkFlate / PDF 
- Adds miniz.c v115_r4 (latest release) to third_party.
   - Merges SkDeflateWStream into SkFlate so including "miniz.c" links
     without duplicating symbols.

The only interesting code change I've made is to remove the line
     fImpl->fZStream.data_type = Z_BINARY;
from SkDeflateWStream::SkDeflateWStream().  miniz doesn't have Z_BINARY
defined, and as far as I can tell, both zlib and miniz ignore data_type.

We should be able to swap skflate.gyp's dependency between zlib.gyp:zlib and
zlib.gyp:miniz at will (except of course on Windows) if we're interested in
zlib itself.  I've left android framework on its own zlib.  I think this all
means we can stop defining SK_NO_FLATE on Windows.

I'll leave the possible cleanup of SK_NO_FLATE itself for another time.  Might
be we always want to keep this dependency optional.

83f56922e2 Fix Mac fontconfig build (try 2) 
The Mac fontconfig just #defines the cache directory, which works fine if fontconfig never has to look up any fonts (the case until now). If it has to actually find fonts from the disk, the cache directory and config directory need to be properly defined as well as running fc-cache to populate the cache directory.

Populating the cache directory can take some time, but should only happen on a clean build. To remove this extra time, we have to not build poppler on Mac, which can now be accomplished with GYP_DEFINES="skia_mac_poppler=0"

Rename all __gl_ functions to Sk__gl_ to avoid conflicting with other copies
of libtess that might be statically linked by Skia clients (done via
gluos.h, rather than touching source directly).

Specfically, this is required to enable incremental linking on Windows builds
of Chromium because WebKit has a copy of libtess also.
