Move its functionality out of readToken() and into its own class.
Callers of the previous readToken() now call
SkPdfNativeTokenizer::readToken(), which in turn calls a function
for writing the diff to a file, if the caller requests it and
PDF_TRACE_DIFF_IN_PNG is defined.
Do not attempt to draw a diff for compatibility sections, which we
do not draw.
Use SkString to handle string manipulation.
Hide globals only used by PDF_TRACE_DIFF_IN_PNG behind that flag.
Remove hasVisualEffects, which always returns true.
Rename gLastOpKeyword to gOpCounter for clarity.
In SkPdfNativeTokenizer, set fEmpty to true when the entire stream
has been read.
Use SkBitmap::copyTo instead of manually copying an SkBitmap.

The only change in behavior is that SkPdfAllocator on SkPdfContext is
no longer allocated on the heap.
In general, I have just moved code.
SkPdfContext:
Inherit from SkNoncopyable.
Make SkPdfContext directly own fTmpPageAllocator. fTmpPageAllocator is
created when SkPdfContext is, and destroyed at the same time as well,
so there is no reason for the extra allocation.
Add the function parseStream. This eliminates code duplication, and
allows making fTmpPageAllocator private.
Move PdfMainLooper into the implementation file, since it is now only
used by parseStream.
Move SkTDictWithDefaultConstructor and render stats info here, in
support of PdfMainLooper.
SkPdfTokenLooper:
Rename PdfTokenLooper to SkPdfTokenLooper.
Move readToken here, unchanged.
Remove tokenizer(), which is unused.
SkPdfNativeDoc:
Remove tokenizerOfPage and tokenizerOfBuffer, which are unused.
SkPdfOps:
Move gPdfOps and PdfOperatorRenderer into a header file (hidden for
now), so they can be accessed by both SkPdfRenderer.cpp and
SkPdfContext.cpp.
SkPdfRenderer:
Harvest things into other files:
PdfMainLooper (and the code that calls it) -> SkPdfContext.
readToken -> SkPdfTokenLooper.

Mostly superficial changes, to help me make sure I understand the
code while making modifications.
SkPdfRenderer:
First class I'm modifying. Move it into include/ and src/ directories.
Inherit from SkNoncopyable.
Replace load() with factory function which returns NULL if the load
fails.
Remove unload() and loaded(), which no longer make sense, since the
factory will return NULL on a failure to load, and unload() happens
on destruction.
Use a const char* for loading a PDF, following the convention of
SkStream::NewFromFile.
Remove unnecessary call to sqrt in SkPDFNativeRenderToBitmap.
Also in SkPDFNativeRenderToBitmap, use an appropriate SkScalar macro
to convert to an integer.
Use this-> when calling member functions.
pdf_viewer_main.cpp:
Call the new interface for SkPdfRenderer.
gyp files:
Refer to the new location of SkPdfRenderer.
