ffc3cfeed1 Allow using binary / octal / hex numbers in XML 
In OpenType Layout tables that is.  Most (all) of the other
tables already use safeEval() which accepts these kinds of
things.

a221a57ccd Improve Version handling 
Version is really just a major.minor, NOT a Fixed.  But it has
been implemented as Fixed.  We now:

  1. Check that major is 1,
  2. If minor is not 0 (only defined for GDEF so far), then
     print the whole thing as hex in XML,
  3. When reading the XML, accept hex,
  4. In all four methods dealing with Version, support both
     fixed version (ie. 1.0), and long version (ie. 0x00010000).

0de65295f6 Remove script to build otData.py 
The was was originally generated, but is static now and this
allows cleaning it up and modifying it.

41caf2dea1 Remove tableStack in favor of countVars 
We only needed tableStack to look back for counts.  So, just store
counts.  Gives ~8 speedup for large fonts I tested.  We are not
faster than not loading fonts lazily without this patch, so the
laziness patch combined with this doesn't have a net negative
performance impact anymore.

f50d0dff86 Load all OpenType sub-structures lazily 
Huge win for subsetter and anyone else who doesn't need the entire
tables.  Subsetting a huge font (eg. NotoSans-Regular.ttf) to a
small set (say, main Cyrillic characters) is something like six
times faster now.  Bulk of time was being spent in blowing up the
GPOS kerning pairs and attach points.  Now we don't load those if
they won't be in the final subset.

Slight slowdown for usecases that need the entire table.

fc4f438496 Fix parsing of hinting instructions that end in a PUSHB 
Sounds useless, but MReifutaiM-Regular.ttf seems to have that, and the
parsing back from XML was failing because we expected a token whereas
after dropping whitespace there wasn't any left.

17700bf926 Handle and warn about out-of-order Coverage table entries 
Apparently the SIL Gentium fonts have wrong sorting in Coverage
tables.  That's broken by the spec, but shapers still work with
such fonts.  So, we warn when reading, and when writing, such
out-of-order coverage tables.

67fef70631 Support decode/encoding of unknown glyf hinting instructions 
New instructions can be defined in the prep program.  We don't
check that the "unknown" instruction was actually defined.  Just
pass it through.

Fixes ttx with Skia.ttf on the Mac OS X.
