This was created by looking at warnings produced by clang's
-Wzero-as-null-pointer-constant. This updates most issues in
Skia code. However, there are places where GL and Vulkan want
pointer values which are explicitly 0, external headers which
use NULL directly, and possibly more uses in un-compiled
sources (for other platforms).

Also: make sure that all SkPDF unit tests are named SkPDF_* to
make testing changes to SkPDF easier. Other cleanup.
Add test: SkPDF_pdfa_document to verify that flag in public API
works.
SkPDF_JpegIdentification test: test slightly malformed JPEGs to
verify that all code paths work.

Motivation: gross code simplification, also no bitset lookups at draw time.
SkPDFFont owns its glyph useage bitset.
SkPDFSubstituteMap goes away.
SkPDFObject interface is simplified.
SkPDFDocument tracks font usage (as hash set), not glyph usage.
SkPDFFont gets a simpler constructor.
SkPDFFont has first and last glyph set in constructor, not adjusted later.
SkPDFFont implementations are simplified.
SkPDFGlyphSet is replaced with simple SkBitSet.
SkPDFFont sizes its SkBitSets based on glyph count.
SkPDFGlyphSetMap goes away.
SkBitSet is now non-copyable.
SkBitSet now how utility methods to match old SkPDFGlyphSet.

Motivation:
SkPDFStream and SkPDFSharedStream now work the same.
Also:
- move SkPDFStream into SkPDFTypes (it's a fundamental PDF type).
- minor refactor of SkPDFSharedStream
- SkPDFSharedStream takes unique_ptr to represent ownership

* do a lot less floating-point math by converting to
an integer as early as possible [faster].
* round rather than truncate.
* use 8 significant digits rather than 9 when possible.

SkPDFUtils now has a special function (SkPDFUtils::AppendColorComponent)
just for writing out (color/255) as a decimal with three digits of
precision.
SkPDFUnion now has a type to represent a color component. It holds a
utint_8, but calls into AppendColorComponent to serialize.
Added a unit test that tests all possible input values.

Note to reviewers: Start with changes to SkPDFTypes.h
Many places that had a bare pointer owning a reference are refactored to
use a sk_sp.
There remain several places where a non-owning pointer `T*` should be
replaced with `const sk_sp<T>&` to eliminate the common pattern
`sk_sp<T>(SkRef(x))`.

Rename to SkDeflate so Chromium builders continue to work
Next, we change remove SkFlate from Chromium build files, then we can delete SkFlate.

When possible use run-time checks (via SkDocument::CreatePDF)
When PDF is disabled, do not compile tests/PDF*.cpp

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.

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

Also: Add SkDeflateWStream and associated unit tests.
SkPDFBitmap is a replacement for SkPDFImage. As of now, it only
supports 8888 bitmaps (the most common case).
SkPDFBitmap takes very little extra memory (aside from refing the
bitmap's pixels), and its emitObject() does not cache any data.
The SkPDFBitmap::Create function will check the canon for duplicates.
This can reduce the size of the output PDF.
Motivation: this gives another ~40% decrease in PDF memory overhead
TODO: Support other ColorTypes and scrap SkPDFImage.
