extdiff: add --from/--to and deprecate -r, as was done for `hg diff`

I recently replaced `hg diff`'s `-r` flag by `--from` and `--to` and
then deprecated the `-r` flag. This patch repeats that for
`hg extdiff`.

Differential Revision: https://phab.mercurial-scm.org/D9624

      the working directory files are compared to its parent.
  
  options ([+] can be repeated):
  
   -o --option OPT [+]      pass option to comparison program
   -r --rev REV [+]         revision
   -c --change REV          change made by revision
      --per-file            compare each file instead of revision snapshots
      --confirm             prompt user before each external program invocation
      --patch               compare patches for two revisions
   -I --include PATTERN [+] include names matching the given patterns

  $ echo b >> a
  $ hg ci -d '1 0' -mtest2

Should diff cloned files directly:

  $ hg falabala -r 0:1
  diffing "*\\extdiff.*\\a.8a5febb7f867\\a" "a.34eed99112ab\\a" (glob) (windows !)
  diffing */extdiff.*/a.8a5febb7f867/a a.34eed99112ab/a (glob) (no-windows !)
  [1]

Can show diff from working copy:
  $ echo c >> a
  $ hg falabala -r 'wdir()' -r 1
  diffing "*\\extdiff.*\\a" "a.34eed99112ab\\a" (glob) (windows !)
  diffing */extdiff.*/a a.34eed99112ab/a (glob) (no-windows !)
  [1]
  $ hg revert a
  $ rm a.orig

  $ hg add
  adding .hgsub
  $ hg ci -Sm "adding subrepo"
  $ echo > .hgsub
  $ hg ci -m "removing subrepo"
  $ hg falabala -r 4 -r 5 -S
  diffing a.398e36faf9c6 a.5ab95fb166c4
  [1]

Test --per-file option:

  > kdiff3 = echo
  > [merge-tools]
  > kdiff3.diffargs=--L1 \$plabel1 --L2 \$clabel \$parent \$child
  > EOF

  $ hg --debug kdiff3 -r0 | grep '^running'
  running 'echo --L1 "@0" --L2 "" a.8a5febb7f867 a' in * (glob) (windows !)
  running "echo --L1 '@0' --L2 '' a.8a5febb7f867 a" in * (glob) (no-windows !)


Test extdiff of multiple files in tmp dir:

  $ hg ci -Am adda
  adding a
  $ echo a >> a
  $ ln -s missing linka
  $ hg add linka
  $ hg falabala -r 0 --traceback
  diffing testsymlinks.07f494440405 testsymlinks

  $ cd ..
