merge: exit early during a no-op update (BC)

hg update . (or equivalents) are effectively no-ops in just about all
circumstances.  These sorts of updates can be especially common in a
bookmark-oriented workflow. This saves us a status check and a manifest
decompression, which means that on a repo with over 210,000 files, this brings
hg update . down from 2.5 seconds to 0.15.

There is one change in behavior: a file that was added, not committed, and then
deleted but not removed used to be removed from the dirstate. With this patch
it isn't. This is what causes the change in test-mq-qpush-exact.t. This seems
like it's enough of an edge case to not be worth handling.

The output of test-empty.t changes because those files are not yet created.

shelving in an empty repo should be possible

create an mq patch - shelving should work fine with a patch applied

  $ echo n > n
  $ hg add n
  $ hg commit n -m second
  $ hg qnew second.patch

shelve a change that we will delete later

  $ echo a >> a/a
  $ hg shelve
  shelved as default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

set up some more complex changes to shelve

  $ echo a >> a/a
  $ hg mv b b.rename
  moving b/b to b.rename/b (glob)
  $ hg cp c c.copy
  $ hg status -C

  A b.rename/b

prevent some foot-shooting

  $ hg shelve -n foo/bar
  abort: shelved change names may not contain slashes
  [255]
  $ hg shelve -n .baz
  abort: shelved change names may not start with '.'
  [255]

the common case - no options or filenames

  $ hg shelve
  shelved as default-01
  2 files updated, 0 files merged, 2 files removed, 0 files unresolved

named shelves, specific filenames, and "commit messages" should all work

expect "a" to no longer be present, but status otherwise unchanged

  $ hg shelve -l --stat
  wibble          (*)    wat (glob)
   a/a |  1 +
   1 files changed, 1 insertions(+), 0 deletions(-)

and now "a/a" should reappear
