Add a first cut at a fastcgi starter program. This does the appropriate

daemonization and sockets magic to let a standard fastcgi program listen
on a TCP port.

Unfortunately due to some requirements of the FastCGI libraries and the
way APR process creation works this currently requires platform specific
code and thus only works on Unix systems.

* support/fcgistarter.c: New program.

* support: Add fcgistarter to svn:ignore.

* support/Makefile.in: Build fcgistarter.
