Filedescriptors

I think it would be useful to add a configure option to force squid
provide for a defineable number of file descriptors, regardless of what the
build-time environment says. It should be a trivial patch.

If nobody objects or gives a reason why it shouldn't be done, I'll take a
stab at the issue code-wise.

Etymology, n.:
	Some early etymological scholars came up with derivations that
	were hard for the public to believe.  The term "etymology" was formed
	from the Latin "etus" ("eaten"), the root "mal" ("bad"), and "logy"
	("study of").  It meant "the study of things that are hard to swallow."
