Patch Submission - Header Manipulation

Dear Squid Folk,

I've implemented a mechamism to arbitrarily add/change/delete headers,
using an extension to the existing redirect_program helper application.

Attach please find a unified diff made against the 20040805 Squid-3.0
snapshot--it should patch more recent ones, of course. Also, please
find a simple example of a redirect program which uses the mechanism to
add a custom header, which shows the basic idea.

Matt
