* src/cff/cffgload.c (cff_decoder_parse_charstrings) <cff_op_get,
cff_op_put>: Appendix B of Adobe Technote #5177 limits the number of
elements for the `get' and `put' operators to 32.

(CFF_Decoder): Use it for `buildchar' and remove `len_buildchar'.

Add a new header named FT_ADVANCES_H declaring some new APIs
to extract the advances of one or more glyphs without necessarily
loading their outlines. Also provide 'fast loaders' for the
TrueType, Type1 and CFF font drivers (more to come later)
* autogen.sh: add checks for minimum version of the 'autotools'
stuff.

* builds/unix/configure.raw (version_info): Set to 9:17:3.
* include/freetype/internal/psaux.h (T1_BuilderRec): Remove `scale_x'
and `scale_y'.

(FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled): New
functions.
* src/cff/cffobjs.h (CFF_Internal): New struct. It is used to
provide global hinting data for both the top-font and all subfonts
(with proper scaling).

code from `cff_size_init'.
(cff_size_init, cff_size_done, cff_size_select, cff_size_request):
Use CFF_Internal and handle subfonts.
(cff_face_init): Handle top-dict and subfont matrices correctly;
apply some heuristic in case of unlikely matrix concatenation
results. This has been discussed with people from Adobe (thanks
goes mainly to David Lemon) who confirm that the CFF specs are fuzzy
and not correct.

FT_SOURCE_FILE, etc.. and added cache-specific macro definitions that
were previously defined in <freetype/ftcache.h>. Added comments to be

needs to added its own directory to the include path at compile time.
Modified all "rules.mk" and "descrip.mms" accordingly..
