remove: rewrite to be ~400x faster, bit more friendly

old remove code called localrepo.changes for each file.
was very expensive:

  $ hg --time rm arch>/dev/null
  Time: real 1066.120 secs (user 1014.450+0.000 sys 18.090+0.000)

new code, same files:

  $ hg --time rm arch>/dev/null
  Time: real 2.770 secs (user 2.190+0.000 sys 0.580+0.000)

also mention "-f" if not removing files. also allow "-f" to forget
added files.

make test a bit better.
