This rearranges the record pointers and types so they can go in a single array, then preallocates some space for them and for the SkVarAlloc.
picture_overhead_draw bench drops from ~1000ns to 500-600ns, with no effect on picture_overhead_nodraw.
I don't see any significant effect on large picture recording times from our .skps.

SkCodec::NewFromStream claims to delete the passed in SkStream on
failure. This allows the caller to pass an SkStream to the function
and not worry about deleting it depending on the return value.
Most of our SkCodecs did not honor this contract though. Update them
to delete the stream on failure. Further, update SkCodec::NewFromStream
to delete the stream if it did not match any subclass, and delete the
SkCodec if we decided to return NULL because it was too big.
Add a test which tests streams which represent the beginnings of
supported format types but do not contain enough data to create an
SkCodec. The interesting part of the test is when we run it on ASAN,
which will report that we leaked something without the other changes.

Add a virtual method on SkStream which will do a "peek" some bytes, so
that those bytes are read, but the next call to read will be
unaffected.
Implement peek for SkMemoryStream, where the implementation is simple
and obvious.
Implement peek on SkFrontBufferedStream.
Add tests.
Motivated by decoding streams which cannot be rewound.

This mirrors the behavior in onGetPixels, and allows the implementation
to share code for handling calls to rewindIfNeeded.
This also fixes a bug where getScanlineDecoder was calling
rewindIfNeeded and treating the result as a bool.
In SkPngCodec, factor out the code to call rewindIfNeeded, and call it
in both onGetPixels and onGetScanlineDecoder.
Update the test to include testing the scanline decoder. Rename "gen"
to "codec" now that it must be an SkCodec.

Depends on https://codereview.chromium.org/1048423003/ (DIFFERENT ISSUE).

Separate out the code for reading the header, and use it to reinitialize
fPng_ptr and fInfo_ptr after a rewind.
Use common code to clean up fPng_ptr and fInfo_ptr, and set them to
NULL and treat them as NULL as appropriate.
Update the test to expect SkPngCodec to succeed.

Motivation: Keep separate features separate. Also, future
linearization work will need to have several objNumMap
objects share a substituteMap. Also "catalog" has a
specific meaning in PDF. This catalog did not map to that
catalog.
- Modify SkPDFObject::emitObject and SkPDFObject::addResources
interface to requiore SkPDFObjNumMap and SkPDFSubstituteMap.
- SkPDFObjNumMap const in SkPDFObject::emitObject.
- Remove SkPDFCatalog.cpp/.h
- Modify SkDocument_PDF.cpp to use new functions
- Fold in SkPDFStream::populate
- Fold in SkPDFBitmap::emitDict
- Move SkPDFObjNumMap and SkPDFSubstituteMap to SkPDFTypes.h
- Note (via assert) that SkPDFArray & SkPDFDict don't need to
check substitutes.
- Remove extra space from SkPDFDict serialization.
- SkPDFBitmap SkPDFType0Font SkPDFGraphicState SkPDFStream
updated to new interface.
- PDFPrimitivesTest updated for new interface.

The primary feature this delivers is SkNf and SkNd for arbitrary power-of-two N. Non-specialized types or types larger than 128 bits should now Just Work (and we can drop in a specialization to make them faster). Sk4s is now just a typedef for SkNf<4, SkScalar>; Sk4d is SkNf<4, double>, Sk2f SkNf<2, float>, etc.
This also makes implementing new specializations easier and more encapsulated. We're now using template specialization, which means the specialized versions don't have to leak out so much from SkNx_sse.h and SkNx_neon.h.
This design leaves us room to grow up, e.g to SkNf<8, SkScalar> == Sk8s, and to grown down too, to things like SkNi<8, uint16_t> == Sk8h.
To simplify things, I've stripped away most APIs (swizzles, casts, reinterpret_casts) that no one's using yet. I will happily add them back if they seem useful.
You shouldn't feel bad about using any of the typedef Sk4s, Sk4f, Sk4d, Sk2s, Sk2f, Sk2d, Sk4i, etc. Here's how you should feel:
- Sk4f, Sk4s, Sk2d: feel awesome
- Sk2f, Sk2s, Sk4d: feel pretty good
No public API changes.

Add and test trunc(), which is what get() used to be before rounding.
Using trunc() is a ~40% speedup on our linear gradient bench.

Replace the implicit curve intersection with a geometric curve intersection. The implicit intersection proved mathematically unstable and took a long time to zero in on an answer.
Use pointers instead of indices to refer to parts of curves. Indices required awkward renumbering.
Unify t and point values so that small intervals can be eliminated in one pass.
Break cubics up front to eliminate loops and cusps.
Make the Simplify and Op code more regular and eliminate arbitrary differences.
Add a builder that takes an array of paths and operators.
Delete unused code.

There is no reason to require the 4 SkPMFloats (registers) to be adjacent.
The only potential win in loads and stores comes from the SkPMColors being adjacent.

SkPDFCatalog:
- remove first-page-specific code (no longer needed, never
used) (e.g. addObject()).
- Make use of SkHashMap for lookups (simplifies code).
- inline all small methods
- emitXrefTable moved to SkPDFDocument.cpp
- no longer store offsets in this data structure (moved to
SkPDFDocument.cpp)
- setFileOffset gone.
- own substitute refs directly.
SkPDFDocument::EmitPDF()
- All sites that call into SkPDFCatalog modified.
- catalog.addObject only called in a single place, after the
resouceSet is built
- offsets moved to local array.
SkPDFPage:
- finalizePage no longer deals with SkPDFCatalog or resource sets.
- GeneratePageTree no longer deals with SkPDFCatalog
SkPDFObjRef
- emitObject respects the substitution map
Unit Tests:
- respect SkPDFCatalog::addObject signature change.
SkTHash:
- #include SkChecksum for SkGoodHash
- Copyright notice added

This seems to fix the miscompilation bug on ARM64 / Release / GCC 4.9.
We switched this over originally for perf issues with NEON, but I can't see any now. Will keep an eye out.
