completion: add a debuglabelcomplete command

When completing a "label" (a symbolic name for a commit), the
bash_completion script currently has to invoke hg three times. For
a large repository, the cost of starting up and loading all the
necessary context over and over is very high.

For instance, in mozilla-central:

  time (export HGPLAIN=1; hg tags -q; hg bookmarks -q; hg branches) >/dev/null
  0.446 sec

Compare with the debuglabelcomplete command that this commit adds:

  time hg debuglabelcomplete >/dev/null
  0.148 sec

This greatly helps responsiveness.
