2b6be207a1 Make SkNoncopyable movable
SkNoncopyable declares (but does not define) its copy constructor and
copy assignment operator. These are also private so the error for misuse
happens at compile-time instead of link-time.

However, this seems to be from before C++11.

Because other constructors were declared, the compiler does not generate
a move constructor or a move assignment operator. The result of this is
perfectly legal non-copying scenarios are also accidentally blocked. An
example of this is returning the non-copyable type. The object being
returned is a candidate for a move, since it is about to be destroyed.
And in C++17 copy elision is actually guaranteed.

600effbdc7 Improve the Codec_end test and add fixes
Better imitate the original Android bug. Create a stream with
multiple images in it, and verify that it successfully decodes after
decoding once.

This exposes a bug in SkPngCodec, which did not work for interlaced
images.

Test more formats that also happen to succeed: ICO, BMP, and WBMP

This explicitly does *not* attempt to fix sampled or subset
decodes, which already stopped early when decoding as an
optimization.

e3302dfb81 Make InstancedRendering more opList-splitting friendly
This CL splits the InstancedRendering class into an allocator and a per-opList op tracker. This was done because we need to allocate the InstancedRendering ops before we know the final destination opList. The InstancedRendering ops are now still all allocated from the same pool but the tracking and execution is done per opList.

2229b57694 jumper, maybe we can just use constants
As long as everything is laid out the same way they were originally, I don't
think there's any reason we can't just use %rip-relative addressing on x86-64.
Basically, we just need to keep all the sections together in order.

Somewhat subtly we cannot just use -D to disassemble all sections.  -D will
double-disassemble[1] some bytes, which throws off our %rip-relative addressing
of constants.  You can see this in PS1.  So we whitelist sections instead.

[1], from man objdump:
   This option also has a subtle effect on the disassembly of instructions in code
   sections.  When option -d is in effect objdump will assume that any symbols
   present in a code section occur on the boundary between instructions and it will
   refuse to disassemble across such a boundary.  When option -D is in effect however
   this assumption is supressed.  This means that it is possible for the output of -d
   and -D to differ if, for example, data is stored in code sections.

83239658f2 Reland "Make SkPngCodec only read as much of the stream as necessary"
(Originally uploaded as 13900.)

Previously, SkPngCodec assumed that the stream only contained one
image, which ended at the end of the stream. It read the stream in
arbitrarily-sized chunks, and then passed that data to libpng for
processing.

If a stream contains more than one image, this may result in reading
beyond the end of the image, making future reads read the wrong data.

Now, SkPngCodec starts by reading 8 bytes at a time. After the
signature, 8 bytes is enough to know which chunk is next and how many
bytes are in the chunk.

When decoding the size, we stop when we reach IDAT, and when decoding
the image, we stop when we reach IEND.

This manual parsing is necessary to support APNG, which is planned in
the future. It also allows us to remove the SK_GOOGLE3_PNG_HACK, which
was a workaround for reading more than necessary at the beginning of
the image.

Add a test that simulates the issue, by decoding a special stream that
reports an error if the codec attempts to read beyond the end.

Temporarily disable the partial decoding tests for png. A larger change
will be necessary to get those working again, and no clients are
currently relying on incrementally decoding PNGs (i.e. decode part of
an image, then decode further with more data).

Include a workaround for older versions of libpng (e.g. 1.2 in
Google3). In older versions, if the row callback is null when the
IDAT header is processed, reading the image will fail. When we see the
IDAT, we save the length and process a recreated IDAT header later,
after the row callback has been set.

Test: Existing tests, plus a new test in dm.

80be240001 Enable fence sync support in ES3 test contexts
This (only?) affects ANGLE. Other ES platforms typically go through
EGLGLTestContext, which manually instantiates an EGLFenceSync.

In general, though, ES3 requires this API, so this is safe. Should give us
more accurate (and much less spammy) output from ES3 ANGLE performance
testing.
