subrepo: only do clean update when overwrite is set (issue3276)

Files in a subrepo were overwritten on update. But this should only happen on a
clean update (example: -C is specified).
Use the overwrite parameter introduced for svn subrepos in c19b9282d3a7 to
decide whether to merge changes (as update) or remove them (as clean).

The new function hg.updaterepo is intruduced to keep all update calls in hg.

test-subrepo.t is extended to test if an untracked file is overwritten
(issue3276). (Update -C is already tested in many places.)
The first two chunks are debugging output which has changed. (Because overwrite
is not always true anymore for subrepos)
All other tests still pass without any change.

Mercurial's documentation is kept in reStructuredText format, which is
a simple plain text format that's easy to read and edit:

It's also convertible to a variety of other formats including standard
UNIX man page format and HTML. You'll need to install Docutils:

Use the Makefile in this directory to generate the man and HTML pages.
