revset: have rev() validate input by repo.changelog.__contains__()

fullreposet.__contains__() will be rewritten in order to support "null"
revision, and "rev()" won't be possible to rely on it.

This backs out eb763217152a, but there is no performance regression now.

revisions:
0) e1dbe0b215ae "l not in fullreposet(repo)"
1) this patch   "l not in repo.changelog"

revset #0: rev(210000)

Do we ever miss a sub-second change?:

  $ for i in 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20; do

  >     echo b > a
  >     hg st
  > done
