[Devel] new error scheme

[Werner LEMBERG]

I've finally committed my changes for the new error scheme.  It's not
documented yet.  Please have a look into the new file ftmoderr.h for
some explanations.  If `FT_CONFIG_OPTION_USE_MODULE_ERRORS' is
undefined, new changes are even fully backwards compatible.

BTW, it seems that we've forgotten to increase the DLL version info in
configure.in.  I suggest that we use 7:0:1, following the rules in
libtool.info, since Tom has added the get_cff_glyph_name() function
for FreeType 2.0.2 -- comments?
