Use unorm shorts for texture coordinates when rendering text.

There are a couple of reasons for this:
- Vulkan does not guarantee conversions from integral vertex attributes
  to floating point shader variables
- This may be faster and more precise on some platforms, as it avoids
  the aforementioned conversion and changes a multiply by a very small
  value to a multiply by a medium-sized value.

Update to a newer version - 1.6.20 (http://sourceforge.net/p/libpng/code/ci/047737496a77eeb97f9991919dac08ca3c149711/).

Update pnglibconf.h. The new version is a copy of the newer version of
the file, with our /* custom settings */ tacked onto the end. (The
custom settings are unchanged from the last version.)

Update the LICENSE. The new version is a copy of the LICENSE that
libpng now includes as a separate file.

Update the README file to reflect the change in source of the LICENSE

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.

We suspect that the original reason to blacklist was this,
