Make initializeColorXform private, and only call in the base class.
Add virtual method to skip initializeColorXform, for classes that do
not need one.
Change SkCodec::FrameInfo's SkAlphaType to an SkEncodedInfo::Alpha.
This allows proper checking internally whether SkCodec needs to do a
color correct premultiply.
Depends on https://chromium-review.googlesource.com/c/620947, for this
API change.

Move common code into the base class, so subclasses need not call
conversion_possible.
Use SkEncodedInfo rather than SkImageInfo, and use the proper frame.
API Changes:
- SkAndroidCodec:
- Add getEncodedInfo(), for SkBitmapRegionCodec
- SkEncodedInfo:
- Add opaque() helper
- SkBitmapRegionDecoder:
- Remove unused conversionSupported

Update NewFromStream to report an error on failure to create an
SkCodec, so that a client can distinguish between
- not enough data
- invalid data
In Chromium, this will allow blink::ImageDecoder to call SetFailed if
the stream is invalid early and we never create an SkCodec. Without
this, ImageDecoder will keep trying to create an SkCodec when it
receives more data.

Previously, if ReadHeader returned false, it deleted the input stream.
But there are a couple of cases where ReadHeader creates an SkCodec and
then returns false. The SkCodec deletes the stream, and then so does
NewFromStream.
Make sure that we do not double delete by only deleting if no SkCodec
was created.
Add a test, so such a double delete will be caught by the bots.

Most SkCodec subclasses did the following to apply their
SkColorSpaceXform:
dstFormat = select_xform_format(dstInfo.colorType());
srcFormat = select_xform_format(<something that doesn't change>);
xformAlphaType = select_xform_alpha(dstInfo.alphaType(),
this->getInfo().alphaType());
this->colorXform()->apply(dstFormat, dst, srcFormat, src, width,
xformAlphaType);
Consolidate the computation of these parameters into SkCodec and add a
new method to SkCodec that calls apply() with those parameters.
Add a SkColorSpaceXform::ColorFormat to SkCodec. This allows the new
method SkCodec::applyColorXform to supply the ColorFormat.

A BMP can have an arbitrarily large width. We typically read a row
into a block of memory before swizzling it to the output. Rather
than calling new to create that block of memory, which may crash
when we run out of memory, call malloc, and return null if malloc
fails.
Add a common base class for Mask and Standard BMP codecs. This class
handles allocating and freeing the buffer.

This is a step towards removing the non-linear blending flag from
SkColorSpace. The flag on SkColorSpace used to control the premul
behavior - now it is controlled by this option.

This limit matches the limit used by Chromium. I am not aware of any
real world BMPs that are larger than this (or even close to it), but
there are some invalid BMPs that are larger than this, leading to
crashes when we try to read a row.

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.

In SkBmpCodec, if the header size does not match a known header,
stop trying to create an SkCodec. We do not know of any BMPs with
arbitrarily sized headers, so this should not cause any real
regressions.
In addition, this fixes a bug where we attempt to read too much data
from a file. Since we attempt to read the header size in one read,
and a size reported by the "BMP" may be larger than SSIZE_MAX, this
will crash when reading from a file.
Add a test.

* Refactor to share code between SkPngCodec and SkWebpCodec
* Didn't end up sharing with SkJpegCodec but did refactor
that code a bit
* Disallow conversions to F16 with non-linear color spaces
* Fail to decode if we fail to create a SkColorSpaceXform
(should be an assert soon). We used to fallback on a
legacy decode if we failed to create the transform.
* A bunch of name changes

All this does is build an SkEncodedInfo for each codec, and
then convert it to an SkImageInfo.
In future steps I intend to:
(1) Use SkEncodedInfo in place of SrcConfig in SkSwizzler.
(2) Support more conversions in SkSwizzler (non-native
BGRA/RGBA, 16-bit components, float, fixed point)
(3) Investigate optimizing conversions from encoded data
to linear color spaces.

I started working on indicating the native encoded formats
and things got really complicated for bmp. I think starting
with this refactor may help a little, and I also think that
this is a good change by itself.

The C++ standard library uses ".reset()" where we sometimes write ".free()".
We also use ".reset()" quite a lot. This standardizes on ".reset()".
This is one more step towards dropping SkAutoTDelete in favor of the standard
std::unique_ptr.

The C++ standard library uses the name "release" for the operation we call "detach".
Rewriting each "detach(" to "release(" brings us a step closer to using standard library types directly (e.g. std::unique_ptr instead of SkAutoTDelete).
This was a fairly blind transformation. There may have been unintentional conversions in here, but it's probably for the best to have everything uniformly say "release".

- Update SkCodec's dox to point out that some of the data must be
read twice in order to decode
- Add an accessor that reports how much is needed for reading twice
- Make SkCodec default to use peek()
If an input stream supports peek()ing, peek() instead of reading.
This way the stream need not implement rewind()
- Make SkCodec use read() + rewind() as a backup
So that streams without peek() implemented can still function
properly (assuming they can rewind).
- read everything we may need to determine the format once
In SkCodec::NewFromStream, peek()/read() 14 bytes, which is enough
to read all of the types we support. Pass the buffer to each subtype,
which will have enough info to determine whether it is the right
type. This simplifies the code and results in less reading and
rewinding.
- NOTE: SkWbmpCodec needs the following number of bytes for the header
+ 1 (type)
+ 1 (reserved)
+ 3 (width - bytes needed to support up to 0xFFFF)
+ 3 (height - bytes needed to support up to 0xFFFF)
= 8
- in SkWebpCodec, support using read + rewind as a backup if peek does
not work.
A change in Android will add peek() to JavaInputStreamAdapter.

We will implement this API using SkCodecs.
SkAndroidCodecs will be used to implement the
BitmapRegionDecoder Java API (and possibly
BitmapFactory).

This CL allows the SkScanlineDecoder to decode partial
scanlines.
This is a first step in efficiently implementing subsetting
