Replay isn't that helpful of a test any more now that we have the more
stringent Quilt tests. Quilt was missing bounding box hierarchies, though,
while Replay was sort of testing RTree (pointlessly, as it was drawing without
any clip). Now Quilt does everything, testing RTree, QuadTree, and TileGrid.
Quilt mode now falls back to drawing all at once (i.e. Replay) for GMs that
don't tile perfectly. Still a TODO to make this check more flexible than exact
pixel matches.
Two GMs fail when using a BBH:
- imageresizetiled
- resizeimagefilter
We think we're not adjusting the bounds of save layers by their paint.
This is probably a bug, but one to be fixed separately from adding new tests.

Now that we're drawing tiles threaded like implside painting, remove the checks
that those lock counts are balanced. They're just not right for anyone anymore.
SkBitmaps themselves are not threadsafe (even const ones), so shallow copy them
on playback of an SkRecord. (The underlying SkPixelRefs are threadsafe.)
Simplify quilt drawing by using SkBitmap::extractSubset. No need for locking.
Bump up to 256x256 tiles. 16x16 tiles just murders performance (way too much
contention). This has the nice side effect of letting us enable a bunch more
GMs for quilt mode; they drew wrong with small tiles but exactly right with large.

Always build the tools with JSON, but either build our own
or use the system's.
Rename skia_build_json_writer to skia_use_system_jsoncpp,
since we now always build with JSON.
Remove SK_BUILD_JSON_WRITER, which was only there so
we could build without JSON it in the framework.

I'm soon going to have SkRecorder start calling getTotalMatrix(), which
would be broken in write-only mode. That change is big and nebulous,
but it's clear kWriteOnly needs to go, so we might as well kill it now.
My notes in bench_playback about kWriteOnly mode being important were
probably overly cautious. I now think this is a fair enough comparison
even re-recording into a read-write canvas.

Like yesterday's change to run CPU-parent child tasks serially in thread, this
reduces peak memory usage by improving the temporaly locality of the bitmaps we
create.
E.g. Let's say we start with tasks A B C and D
Queue: [ A B C D ]
Running A creates A' and A", which depend on a bitmap created by A.
Queue: [ B C D A' A" * ]
That bitmap now needs sit around in RAM while B C and D run pointlessly and can
only be destroyed at *. If instead we do this and push dependent child tasks
to the front of the queue, the queue and bitmap lifetime looks like this:
Queue: [ A' A" * B C D ]
This is much, much worse in practice because the queue is often several thousand
tasks long. 100s of megs of bitmaps can pile up for 10s of seconds pointlessly.
To make this work we add addNext() to SkThreadPool and its cousin DMTaskRunner.
I also took the opportunity to swap head and tail in the threadpool
implementation so it matches the comments and intuition better: we always pop
the head, add() puts it at the tail, addNext() at the head.

These tasks tend to do similar things with similar sized bitmaps, so running
them serially means we tend to hold 2x bitmaps at a time (golden and
comparison) instead of (1+k)x bitmaps (golden and k concurrent comparisons).
We still migrate GPU task's children over to the main CPU thread pool,
because they'll run faster there and free up capacity on the GPU thread.

Before this change, when limited to 4G, pathops threaded tests were the weak
link RAM-consumption-wise (in thread-local font caches) up until about 12
cores, where other problems begin to pile up too.
Tested by running:
ulimit -Sv 4194304
out/Debug/dm --threads N [--pathOpsSingleThread]
After this, we're _probably_ good to go on 32-bit machines with 8 cores.

- Rename TileGrid -> Quilt to avoid the name overload.
- Tag all failing GMs with kSkipTiled_Flag.
You may be wondering, do any GMs pass? Yes, some do! And that trends towards all of them as we increase --quiltTile.
Two GMs only fail in --quilt mode in 565. Otherwise all GMs which fail are skipped, and those which don't fail aren't. (The 8888 variants of those two GMs are skipped even though they pass.)

This CL sets the stage for retracting the SkPicture::kOptimizeForClippedPlayback_RecordingFlag flag
from the public API (more work needs to be done in Blink & Chrome). In the new world the only way
to set this flag (and thus instantiate an SkPicture-derived
class) is by passing a factory to the SkPictureRecorder class. This is to get all clients always using
factories so that we can then change the factory call used (i.e., so the factory just creates a BBH) and
do away with the SkPicture-derived classes.
