hinting and a memory leak with some large Asian CFF fonts

        which happens when FT_Done_Library is called with opened CFF_Faces in
        it. We need to close all faces before destroying the modules, or else
        some bad things (memory leaks) may happen.

Werner Lemberg 913a365090 Because FT_Load_Glyph expects CID values for CID-keyed fonts, the
test for a valid glyph index must be deferred to the font drivers.

    note also that current Make-based build system still compiles the
    modules though...

    * include/freetype/config/ftoption.h: added FT_STRICT_ALIASING,
    which controls the definitions of the memory management functions
    to avoid warnings with recent versions of GCC. this macro is
    only here to be disabled, in case we detect problems with the
    new scheme.

FT_Request_Metrics), src/base/ftobjs.c (FT_Select_Metrics,
FT_Request_Metrics): New base functions to set the font metrics.  They
were part of FT_Select_Size/FT_Request_Size and are made independent
functions so that metrics are not set again and again.

* src/base/ftobjs.c (FT_Select_Size, FT_Request_Size): Metrics are set
only when driver's size_select/size_request is NULL.  That is, drivers
should set the metrics themselves.

does cause some problems without rounding.

s/index/strike_index/.
The scaled metrics are always preferred over strikes' metrics, even
when some strike is selected.  This is done because the strikes'
metrics are not reliable, e.g., the sign of the descender is wrong for
some fonts.

files were committed.  Just a catch-up.

tt_face_load_strike_metrics), src/sfnt/ttsbit0.c
