topics: update current topic to the topic of newly rebased commit (issue5551)
The rebase code passes branchmerge equals to True while updating to the rebased
commit. We need to make sure topic is preserved even after rebase and hence we
need to update the topic even when branchmerge argument is set to True. But
there is a twist in the tale, merge also uses this part of code and we allow to
update topic when brancmerge is True, in merge cases the topic after merge will
the topic of the destination commit, not the topic of working directory parent.
So we need the function to have information about whether a rebase is going on,
and we do it by wrapping the rebase command and storing some value in the
config. This is a bit hacky but works for now. This patch fixes issue related to
loosing of topic while rebase.
Thanks to Boris Feld for the rigourous tests.

aliases: refresh
combine a changeset with updates and replace it with a new one
Commits a new changeset incorporating both the changes to the given files
and all the changes from the current parent changeset into the repository.
See 'hg commit' for details about committing changes.
If you don't specify -m, the parent's message will be reused.
Behind the scenes, Mercurial first commits the update as a regular child
of the current parent. Then it creates a new commit on the parent's
parents with the updated contents. Then it changes the working copy parent
to this new combined changeset. Finally, the old changeset and its update
are hidden from 'hg log' (unless you use --hidden with log).
Returns 0 on success, 1 if nothing changed.
options ([+] can be repeated):
-A --addremove mark new/missing files as added/removed before
committing
-e --edit invoke editor on commit messages
--close-branch mark a branch as closed, hiding it from the branch
list
-s --secret use the secret phase for committing
-I --include PATTERN [+] include names matching the given patterns
-X --exclude PATTERN [+] exclude names matching the given patterns
-m --message TEXT use text as commit message
-l --logfile FILE read commit message from file
-d --date DATE record the specified date as commit date
-u --user USER record the specified user as committer
-D --current-date record the current date as commit date
-U --current-user record the current user as committer
-i --interactive use interactive mode
