An RLE bmp reports how many bytes it should contain. This number may be
incorrect, or it may be a very large number. Previously, we buffered
all bytes in a single allocation. Instead, use a fixed size buffer and
only read what fits into the buffer. We already have code to refill the
buffer if there is more data, so rely on that to keep reading.
Choose an arbitrary size for the buffer. It is larger than the maximum
possible number of bytes we need to read at once.
Add a test with a test image that reports a very large number for
the number of bytes it should contain. With the old method, we would
allocate 4 gigs of memory to decode this image, which is unnecessary
and may result in OOM.

The original is at:
https://skia-review.googlesource.com/c/6887/
The only change to the original is to temporarily comment out
a check in SkImageInfoPriv.h until a Chrome unit test can
be fixed.
The idea is share these standards for the following:
SkImage::readPixels()
SkCanvas::readPixels()
SkCanvas::writePixels()
SkBitmap::readPixels()
SkPixmap::readPixels()
On the raster side, SkPixmap::readPixels() is the right
place to check, because all raster calls go through
there eventually. Then at lower levels (ex: SkPixelInfo),
we can assert.
There's not really a unifying location for gpu calls,
so I've added this in multiple places. I haven't really
dug into the gpu code to SkASSERT() on invalid cases
that we will have already caught.
Follow-up work:
Similar refactor for SkReadPixelRec::trim().
Code cleanup in SkPixelInfo::CopyPixels()

(1) Parse ICC gray profiles into RGB SkColorSpace objects. This is
easy - "gray transfer fn + white point" is subset of "RGB transfer fns
+ matrix". This makes it easier/possible for the drawing code to reason
about color spaces attached to kGray buffers.
(2) Allow gray images to be tagged with gray ICCs OR rgb ICCs. ICC gray
forces to designer to use "D50 gray". It is not uncommon to see gray
images with RGB profiles - and this actually allows the designer to
choose more kinds of gray (ex: sRGB gray).
(3) Make SkJpegCodec support gray images with RGB ICCs.
(4) Make SkPngCodec support gray images with Gray ICCs.
(5) Delete gray from SkColorSpace_A2B - we no longer create these objects
for gray profiles.

Alpha type is not (and never will be) part of pixel config, so the logic

With that out of the way, we can easily supply a full info at the two
