Fully support TTCs.
This patch combines the preparation steps from the last four commits.
ttfautohint now loops over the font multiple times:
1. Extract the necessary data from all SFNT tables in all subfonts.
2. Merge the glyph coverage data of subfonts which share the same `glyf'
table. In other words, if glyph X is addressed only in the cmap of
subfont A, and glyph Y is addressed only in the cmap of subfont B,
ttfautohint merges the script coverage information so that it can
access both X and Y while creating hints.
3. Create tables for each subfont. If two subfonts share a `glyf' table,
they automatically share a `prep', `fpgm', and `cvt' table also.
