        Bug 563557 – set g_get_prgname() in fc pattern

        * docs/pango-sections.txt:
        * pango/pangofc-fontmap.c (pango_fc_make_pattern):
        * pango/pangofc-fontmap.h:
        Add PANGO_FC_PRGNAME which is the fontconfig element "pangoprgname".
        Populate it on all our fontconfig search patterns using
        g_get_prgname().  See bug for sample use.
