e12a090a63 make some textblob builders private for now
Move SkTextBlobBuilder::allocRunText* to private: for the time
being, to reduce the documented interface footprint.

No code is deleted; the functions may be restored when a
client is ready to call them.

Also, add SkTextBlob::MakeFromString to complement
SkTextBlob::MakeFromText.

785586af7d remove unused serialization in textblob
The SKTextBlob serialization code that is tested by Skia is
unused by Chrome. The serialization code that is
used by Chrome is untested by Skia.

Remove the unused code; test the used code.

The code path introduced nearly a year ago,
likely for slimming paint, attempts to make
text blobs smarter by allowing the reuse of typefaces.

Maybe there needs to be a Chrome bug / feature
request to use this?

If if turns out there is no interest to do so,
This CL aligns used interfaces with tests.

b4aab9ae6d Replace SkFAIL with SK_ABORT.
SkFAIL is a legacy macro which is just SK_ABORT. This CL mechanically
changes uses of SkFAIL to SK_ABORT in preparation for its removal. The
related sk_throw macro will be changed independently, due to needing to
actually clean up its users.

Only expect this if the typeface is empty (e.g. faked out for testing)

3a9a7a310c Remove run count field from SkTextBlob.
We can flag the last run record instead.  Run iteration is always
sequential, so no penalty.

As a side effect, we can no longer allow instantiation of zero-run text
blobs - but that seems like a good idea anyway.

337797580d Make SkTextBlob::RunIterator public.
Motivation: This will be easier than adding a friend every time I want
to create a one-off SkCanvas subclass or SkRemote::Encoder subclass.

See also: SkPath::Iter.

0b01da7bca Fix TextBlobTest valgrind error
When converting text to glyph IDs, the paint needs to reflect the actual
text encoding.

9ae8fe1c60 [SkTextBlob] Remove incorrect builder assert
At the end of TightRunBounds, glyphPosX cannot exceed the start of the
next run.  But glyphPosY is running ahead of glyphPosX (for
kFull_Positioning) => the glyphPosY assert is incorrect.

Since the two pointers advance in lock-step, there isn't much value in
the glyphPosY assert anyway - we might as well remove it.

3c196def91 Souped-up SkTextBlob.
Refactored text blob backend for improved performance: instead of using
separate buffers for runs/positions/glyphs, everything is now packed in
a consolidated slab (including the SkTextBlob object itself!).

Benefits:

 * number of allocations per blob construction reduced from ~4 to 1
   (also minimizes internal fragmentation)
 * run record size reduced by 8 bytes

This takes the blob construction overhead down to negligible levels
(for the current Blink uncached textblob implementation).

Unfortunately, the code is much more finicky (run merging in
particular) -- hence the assert spree.

Multi-run blobs are vulnerable to realloc storms but this is not a
problem at the moment because Blink is using one-run blobs 99% of the
time. Will be addressed in the future.
