[MERGE] Replacing reply headers [was: Force Basic auth for Java applets]

Hi,

the patch attached restores the functionality to replace reply
headers as found in Squid 2 (header_replace worked for both
request and reply headers back then) and updates the release
notes as requested by Amos.

The patch is against HEAD. I'm also using it with Squid 3.1.11
where I had to s/IFDEF: USE_HTTP_VIOLATIONS/IFDEF: HTTP_VIOLATIONS/.
In case a separate patch is needed, please let me know.

Thanks,
Marco

P.S.: I'm not subscribed to squid-dev (only squid-users), please
CC me when replying.

For us it is accepted, merge/send or diff patches.

Just needs to go to the squid-dev mailing list with an appropriate commit
message. This type of bzr merge patch needs a [MERGE] on the subject line
for the automatics.

I've done the audit part for this, looks fine. I'll port this back to 3.1
stable as a regression fix, so the doc/release-notes/release-3.1.sgml file
also needs updating as part of the patch (ignore the .html).
Specifically; adding header_replace entry under changed config options to
say its deprecated by request_header_replace. Along with entries for the
two new names under added config options.

Cheers.

Amos
