subrepo: lazily update git's local tracking branches
This continues the strategy of separation between hg pull and hg update in
git subrepos by only dealing with git's branches on an update. This behavior
tries to cover the bare essentials of the semantics of git pull in the subrepo
when the parent repo does hg pull and hg update.

Rebase - try to rebase on an applied mq patch:
$ hg rebase -s 1 -d 3
abort: cannot rebase onto an applied mq patch
[255]
Rebase - same thing, but mq patch is default dest:
$ hg up -q 1
$ hg rebase
abort: cannot rebase onto an applied mq patch
[255]
$ hg up -q qtip
Rebase - generate a conflict:
$ hg rebase -s 2 -d 1
merging f
warning: conflicts during merge.
merging f failed!
abort: unresolved conflicts (see hg resolve, then hg rebase --continue)
[255]
Fix the 1st conflict:
$ echo mq1r1 > f
$ hg resolve -m f
$ hg rebase -c
merging f
warning: conflicts during merge.
merging f failed!
abort: unresolved conflicts (see hg resolve, then hg rebase --continue)

Fix the 2nd conflict:
$ echo mq1r1mq2 > f
$ hg resolve -m f
$ hg rebase -c
