Move public headers into a separate include/woff2 directory
...
This is a first step to make WOFF2 a shared library. Public headers are moved
in their own directory to make the public API clearer. This is similar to
the c/include/brotli/ directory in Brotli. "using" commands are also removed
from the public headers, so that callers won't have unexpected side effect
when including the files.

Fix simple glyph bounding box handling

Per the spec[1], the bounding box should be calculated and if it differs
from the one stored on the font, the original should be written
otherwise it should be omitted. On the other hand, the bounding box of
composite glyphs should be always written.
Fixes #12 .
