Compat: accept -with-maxfd=N

For backward compatability with Squid-2 we now accept the -with-maxfd
configure setting as an alternative to --with-filedescriptors.

--with-filedescriptors is still preferred, and the only one documented.
If both are set the value of --with-file-descriptors=N will be used.
