[PATCH 0/3 (resend)] gitweb: Miscelanous fixes

There were a few gitweb patches which were send (and seemed to be accepted) before 1.5.4-rc0 (and before feature freeze request), but are not in 'master'; it is not even in 'offcuts' (what is this branch for by the way?).

All those patches are simple bugfixes (well, perhaps exept last one, but even it can be treated as bugfix). All passes the gitweb test: t9500-gitweb-standalone-no-errors (not that it says much).

Patches are independent conceptually, and should be textually independent. Apply to 'master'

Table of contents:
 [PATCH] gitweb: Make config_to_multi return [] instead of [undef]
 [PATCH] gitweb: disambiguate heads and tags withs the same name
 [PATCH] gitweb: Teach "a=blob" action to be more lenient about
         blob/file mime type

P.S. I could not check if gitweb shows correct output as my Apache has very mysteriously stopped working and refused to restart. It might have been cause by an incident when runaway program filled whole disk space with log, leaving no space on device... but it might not.
