[Fontconfig] robustness of the mmap cache branch

[James Cloos]

Incidently, it would be useful to have a program that can read in a
specified fonts.cache-2 (ui a la cat(1)'s ui) and print the equivalent
fonts.cache-1.  

The easiest way, currently, to determine the name needed to get a font
known by filename is to grep for the filename in fonts.cache-1; it'd
be a shame to loose that.

I'll look into how hard that'll be to write, but if you can whip it up
w/o thinking please do so. :-)
