hgweb: wrap {entries}* of tags with mappinggenerator

They were functions returning a generator of mappings. The laziness is
handled by the mappinggenerator class.

fixbundle() {
    grep -v 'saving bundle' | grep -v 'saved backup' | \
        grep -v added | grep -v adding | \
        grep -v "unable to find 'e' for patching" | \
        grep -v "e: No such file or directory" | \
    cat
