* src/sfnt/sfobjs.c (tt_face_get_name): fixing a bug that
caused FreeType to crash when certain broken fonts (e.g.
"hya6gb.ttf") were opened.

FreeType to crash when certain broken fonts (e.g. "hya6gb.ttf")

* src/sfnt/ttload.c (TT_Load_Names): applied a small work-around to
manage fonts containing a broken name table (e.g. "hya6gb.ttf")

manage fonts containing a broken name table (e.g. "hya6gb.ttf").
* src/sfnt/ttcmap0.c (tt_cmap4_validate):
fixed over-restrictive validation test. the charmap validator
now accepts overlapping ranges in format 4 charmaps.

switched to a binary search algorithm. Certain fonts contain
more than 170 distinct segments !!

* include/freetype/config/ftstdlib.h: adding an alias for the
'exit' function. This will be used in the near future to panic
in case of un-expected exception (which shouldn't happen in
theory, but as everyone knows, shit happens :-) )

function. This will be used in the near future to panic in case of
unexpected exception (which shouldn't happen in theory).
* include/freetype/internal/fthash.h, src/base/fthash.c:
adding a generic implementation of dynamic hash tables using
linear algorithm (to get rid of 'stalls' during resizes). This
will be used in the future in at least three parts of the
library: the cache sub-system, the object sub-system and
the memory debugger.

* include/freetype/internal/ftcore.h: added this header file to
group all new definitions related to exception handling and
memory management. It's very likely that this file will disappear

[Well, this is not really correct. Recently, a perl implementation
of make called `makepp' has appeared which can also build FreeType 2
successfully on Unix platforms. See http://LNC.usc.edu/~holt/makepp
