[psaux] Fix Type 1 hinting.

Type 1 hinting breaks sometimes when mid-charstring hints should have been in
the initial hintmap. This fix adds a preprocessing pass that reads all hints
and builds the correct initial hintmap first, before proceeding to build the
glyph outline.

* src/psaux/psintrp.c (cf2_interpT2CharString): Add boolean flag.
Ignore outline commands and hint changes on first pass.
<endchar>: Add section to build hintmap and rewind.
