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'
