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.

Tests for changing and clearing topics
======================================

  $ . "$TESTDIR/testlib/topic_setup.sh"
  $ cat <<EOF >> $HGRCPATH
  > [experimental]
  > # disable the new graph style until we drop 3.7 support
  > graphstyle.missing = |
  > evolution=createmarkers, allowunstable
  > [phases]
  > publish=false
  > [alias]
  > glog = log -G -T "{rev}:{node|short} \{{topic}}\n{desc}  ({bookmarks})\n\n"
  > EOF

About the glog output: {} contains the topic name and () will contain the bookmark
