Reason for revert:
Going to try to just remove the many-at-once clone interface

This adds an alternate version of SkPicture::clone for two reasons:
1) Chromium uses the SkPicture copy constructor to unpack the pictures from the old-style clone interface (and I would like to remove the copy ctor)
2) This is part of the long term plan to wean Chrome off of cloning. Once pictures are thread safe we will switch the new SkPicture::clone call to just return 'this'. From there it is a small step to removing clone entirely.
Note that the two versions of clone() is temporary. Once this is landed (and rolled) I will land a Chrome-side patch to remove their use of the old interface (Use new SkPicture::clone interface - https://codereview.chromium.org/380323002/)

This CL begins setting up the SkPicturePlayback split by simplifying the class and componentizing it a bit. It:
fuses SkPictureData::OperationList into SkPicture::OperationList
adds a handleOp method to SkPicturePlayback that can be reused by derived classes
removes a couple debugging tools (ENABLE_TIME_DRAW & SPEW_CLIP_SKIPPING)

This splits the playback functionality out of SkPictureData. The old SkPictureData::draw method is pulled out along
with its supporting functions as verbatim as possible. Some follow on CLs will be required to:
re-enable profiling in the debugger (and remove the vestiges of SkTimedPicture)
re-enable display of command offsets in the picture (this should probably wait until we've switched to SkRecord though)
Clean up CachedOperationList (maybe fuse with SkPicture::OperationList)
Split SkPicturePlayback into a base class and two derived classes
Implement parallel version of GatherGPUInfo for SkRecord
Landing this is blocked on removing Android's use of the abortPlayback entry point.

- support fRecord in copy constructor
- support SkDrawPictureCallback
Moved SkDrawPictureCallback to its own header so
SkRecordDraw can include it without pulling in all of
SkPicture.
Adding an SkAutoSaveRestore to SkRecordDraw was the easiest
way to match the balance guarantees of the callback, and
probably not a bad idea in general. Updated its tests.

I've tagged all the functions in SkPicture.cpp is // fRecord TODO or // fRecord
OK, depending on whether or not they're totally broken when used from an
SkRecord-based picture. Obviously next steps are to eliminate all the TODOs,
then clean up the notes.
I converted SkPicture over to smart pointers too. It's particularly helpful
that the smart pointers initialize to NULL by default.
For now I've got all the SkRecord-based code jammed in at the bottom of the file. I figure it'll help me keep things straight for a bit, then we can rearrange later.

This CL improves the separation of the SkPicture and SkPictureRecord classes. It delays creation of the SkPicture (in SkPictureRecorder) until recording is actually completed. To accomplish this the SkRecord-derived classes now get SkPathHeap and SkPictureContentInfo members that are absorbed by the SkPicture when it is constructed.
As an ancillary change, this CL also moves the SkPictureContentInfo object from SkPicture to SkPicturePlayback. This is intended to centralize all the data in the SkPicturePlayback object.

This is split out of https://codereview.chromium.org/316063005/ for clarity. Keeping in mind that SkPicture::FakeEndRecording is now only called from SkPictureRecorder, its deepCopy parameter is no longer necessary. This is b.c., given the new Picture recording semantics (where SkPictures can no longer be actively recording), cloning for thread safety only happens when an SkPicturePlayback has already been allocated (i.e., it happens in the SkPicturePlayback copy constructor.

My goal here was to add a single location where we could patch up the created PicturePlayback. Unfortunately, the complexity of the recording process (e.g., the BBH) makes this quite complex.
I will investigate altering the behavior of SkPicturePlayback to account for a potentially unbalanced set of saves/saveLayers.

This CL begins the process of making SkPicturePlayback & SkPictureRecord independent of SkPicture. It just moves the PathHeap into SkPicture to get a feel for where all this is going to lead.
Some items of note:
SkTimedPicture (debugger/QT) should wind up being just an SkPicturePlayback-derived object.
All the flattening & unflattening should migrate out of SkPicturePlayback and into SkPicture.
SkPicture::initForPlayback should eventually become something just SkPictureRecorder::endRecording calls.
SkPicture is passed into SkPicturePlayback's & SkPictureRecord's constructors. SkPicturePlayback only
holds onto a "const SkPicture*". The SkPicturePlayback:: CreateFromStream & CreateFromBuffer methods pass a non-const
SkPicture* down the call stack.

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.
