[PATCH 1/2 v2] Use one single function to register fpe functions

[Tiago Vignatti]

X server doesn't need to understand fpe internals, so let it transparent
turning all registration functions in a single one. For that, fill the already
existent register_fpe_functions().

Some X servers don't want font server support, so this patch also sets font
server support to be configured in build time.

In my machine, I see 20kB of RSS being saved in libXfont mapped in Xorg
process when I disabled font server support and other kind of fonts in the
library (--disable-pcfformat --disable-bdfformat --disable-snfformat
--disable-freetype --disable-fc).

The default library built was taking:
   text    data     bss     dec     hex filename
 261847    4484    1536  267867   4165b ./lib/libXfont.so

and with these flags, it jumps to:
   text    data     bss     dec     hex filename
 157764    2428    1188  161380   27664 ./lib/libXfont.so
