21bd9c2f8c [psaux] Fix Type 1 glyphs with too many stem hints. 
According to the CFF specification, charstrings can have up to 96 stem
hints. Due to hint replacement routines in Type 1 charstrings, some
glyphs are rejected by the Adobe engine, which implements the above
limit. This fix turns off hinting for such glyphs.

* src/psaux/pshints.c (cf2_hintmap_build): Reset the error from calling
`cf2_hintmask_setAll' on a problematic Type 1 charstring and turn off
hinting.

766f529a31 Rename files. 
Replace the `cf2' file name prefix with `ps' as the Adobe engine
will be used for both PostScript Types 1 and 2 (CFF) instead of just
CFF.

s/cf2/ps/ for all following.

* src/psaux/cf2*: Rename files.
* src/psaux/*: Update includes.

* src/psaux/Jamfile (_sources), src/psaux/rules.mk (PSAUX_DRC_SRC,
PSAUX_DRV_H): Update file references.
