templates: add 'bisect' keyword to return a cset's bisect status

This new 'bisect' template expands to a cset's bisection status (good,
bad and so on...). There is also a new 'shortbisect' filter that yields
a single char representing the cset's bisection status.

It uses the two recently-added hbisect.label() and .shortlabel() functions.

Example output using the repository in test-bisect2.t, and some made-up
state of the 'end at merge' test (with graphlog, it's so explicit):

  $ hg glog --template '{rev}:{node|short} {bisect}\n'  \
            -r 'bisect(range)|bisect(ignored)'
  o  17:228c06deef46: bad
  |
  o  16:609d82a7ebae: bad (implicit)
  |
  o    15:857b178a7cf3: bad
  |\
  | o  13:b0a32c86eb31: good
  | |
  | o  12:9f259202bbe7: good (implicit)
  | |
  | o  11:82ca6f06eccd: good
  | |
  @ |    10:429fcd26f52d: untested
  |\ \
  | o |  9:3c77083deb4a: skipped
  | |/
  | o  8:dab8161ac8fc: good
  | |
  o |    6:a214d5d3811a: ignored
  |\ \
  | o |  5:385a529b6670: ignored
  | | |
  o | |  4:5c668c22234f: ignored
  | | |
  o | |  3:0950834f0a9c: ignored
  |/ /
  o /  2:051e12f87bf1: ignored
  |/

And now the same with the short label:

  $ hg log --template '{bisect|shortbisect} {rev}:{node|short}\n'

Create a repository:

  $ hg init t
  $ cd t

Make a changeset:

  $ echo a > a
  $ hg add a
  $ hg commit -m test

This command is ancient:

  $ hg history
  changeset:   0:acb14030fe0a
  tag:         tip
  user:        test
  date:        Thu Jan 01 00:00:00 1970 +0000
  summary:     test
  

Verify that updating to revision 0 via commands.update() works properly

  $ cat <<EOF > update_to_rev0.py
  > from mercurial import ui, hg, commands
  > myui = ui.ui()
  > repo = hg.repository(myui, path='.')
  > commands.update(myui, repo, rev=0)
  > EOF
  $ hg up null
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ python ./update_to_rev0.py
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg identify -n
  0
 

Poke around at hashes:

  $ hg manifest --debug
  b789fdd96dc2f3bd229c1dd8eedf0fc60e2b68e3 644   a

  $ hg cat a
  a

Verify should succeed:

  $ hg verify
  checking changesets
  checking manifests
  crosschecking files in changesets and manifests
  checking files
  1 files, 1 changesets, 1 total revisions

At the end...
