gitweb: Change parse_commits signature to allow for multiple options
Change order of parameters in parse_commits() to have $filename
before @args (extra options), to allow for multiple extra options,
for example both '--grep=<pattern>' and '--fixed-strings'.
Change all callers to follow new calling convention.
