templatekw: add a {negrev} keyword

Revision numbers are getting much maligned for two reasons: they are
too long in large repos and users get confused by their local-only
nature. It just occurred to me that negative revision numbers avoid
both of those problems. Since negative revision numbers change
whenever the repo changes, it's much more obvious that they are a
local-only convenience. Additionally, for the recent commits that we
usually care about the most, negative revision numbers are always near
zero.

This commit adds a negrev templatekw to more easily expose negative
revision numbers. It's not easy to reliably produce this output with
existing keywords due to hidden commits while at the same time
ensuring good performance.

  $ hg init

  $ echo a > a
  $ hg ci -qAm 'add a'

  $ hg init subrepo
  $ echo 'subrepo = http://example.net/libfoo' > .hgsub
  $ hg ci -qAm 'added subrepo'

  $ hg up -qC 0
  $ echo ax > a
  $ hg ci -m 'changed a'
  created new head

  $ hg up -qC 1
  $ cd subrepo
  $ echo b > b
  $ hg add b
  $ cd ..

Should fail, since there are added files to subrepo:

  $ hg merge
  abort: uncommitted changes in subrepository "subrepo"
  [255]

Deleted files trigger a '+' marker in top level repos.  Deleted files are also
noticed by `update --check` in the top level repo.

  $ hg ci -Sqm 'add b'
  $ echo change > subrepo/b

  $ hg ci -Sm 'change b'
  committing subrepository subrepo

  $ rm a
  $ hg id
  9bfe45a197d7+ tip
  $ hg sum
  parent: 4:9bfe45a197d7 tip
   change b
  branch: default
  commit: 1 deleted (clean)
  update: 1 new changesets, 2 branch heads (merge)
  phases: 5 draft

  $ hg up --check -r '.^'
  abort: uncommitted changes
  [255]
  $ hg st -S
  ! a
  $ hg up -Cq .

Test that dirty is consistent through subrepos

  $ rm subrepo/b

A deleted subrepo file is flagged as dirty, like the top level repo

  $ hg id --config extensions.blackbox= --config blackbox.dirty=True \
  > --config blackbox.track='command commandfinish'
  9bfe45a197d7+ tip
  $ cat .hg/blackbox.log
  * @9bfe45a197d7b0ab09bf287729dd57e9619c9da5+ (*)> serve --cmdserver chgunix * (glob) (chg !)
  * @9bfe45a197d7b0ab09bf287729dd57e9619c9da5+ (*)> id --config *extensions.blackbox=* --config *blackbox.dirty=True* (glob)
  * @9bfe45a197d7b0ab09bf287729dd57e9619c9da5+ (*)> id --config *extensions.blackbox=* --config *blackbox.dirty=True* exited 0 * (glob)

TODO: a deleted file should be listed as such, like the top level repo

  $ hg sum
  parent: 4:9bfe45a197d7 tip
   change b
  branch: default
  commit: (clean)
  update: 1 new changesets, 2 branch heads (merge)
  phases: 5 draft

Modified subrepo files are noticed by `update --check` and `summary`

  $ echo mod > subrepo/b
  $ hg st -S
  M subrepo/b

  $ hg up -r '.^' --check
  abort: uncommitted changes in subrepository "subrepo"
  [255]

  $ hg sum
  parent: 4:9bfe45a197d7 tip
   change b
  branch: default
  commit: 1 subrepos
  update: 1 new changesets, 2 branch heads (merge)
  phases: 5 draft

TODO: why is -R needed here?  If it's because the subrepo is treated as a
discrete unit, then this should probably warn or something.
  $ hg revert -R subrepo --no-backup subrepo/b -r .

  $ rm subrepo/b
  $ hg st -S
  ! subrepo/b

`hg update --check` notices a subrepo with a missing file, like it notices a
missing file in the top level repo.

  $ hg up -r '.^' --check
  abort: uncommitted changes in subrepository "subrepo"
  [255]

  $ hg up -r '.^' --config ui.interactive=True << EOF
  > d
  > EOF
  file 'b' was deleted in local [working copy] but was modified in other [destination].
  What do you want to do?
  use (c)hanged version, leave (d)eleted, or leave (u)nresolved? d
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

XXX: There's a difference between wdir() and '.', so there should be a status.
`hg files -S` from the top is also missing 'subrepo/b'.

  $ hg st -S
  $ hg st -R subrepo
  $ hg files -R subrepo
  [1]
  $ hg files -R subrepo -r '.'
  subrepo/b

  $ hg bookmark -r tip @other
  $ echo xyz > subrepo/c
  $ hg ci -SAm 'add c'
  adding subrepo/c
  committing subrepository subrepo
  created new head
  $ rm subrepo/c

Merge sees deleted subrepo files as an uncommitted change

  $ hg merge @other
  abort: uncommitted changes in subrepository "subrepo"
  [255]
