grab: add a command to grab a commit and update to it
This patch adds anew command `hg grab` which will pick a commit and put it on
the top of the working directory parent and updates to it.
Earlier grab was an alias for `hg rebase -r <rev> -d .` which is now deleted to
make sure `hg grab` resolves to the grab command and that alias.
Continuing interrupted grab functionality is also there using the evolvestate
class.
Tests are also added for the new introduced command.
====================================
Testing head checking code: Case C-2
====================================
Mercurial checks for the introduction of new heads on push. Evolution comes
into play to detect if existing branches on the server are being replaced by
some of the new one we push.
This case is part of a series of tests checking this behavior.
Category C: case were the branch is only partially obsoleted
TestCase 2: 2 changeset branch, only the base is rewritten
.. old-state:
..
.. * 2 changeset branch
..
.. new-state:
..
.. * 1 new changesets branches superceeding only the base of the old one
.. * The old branch is still alive (base is obsolete, head is alive)
..
.. expected-result:
..
.. * push denied
