subrepos: abort commit by default if a subrepo is dirty (BC)

This changeset flips the default value of ui.commitsubrepos setting
from True to False and adds a --subrepos flag to commit.

The commit, status, and diff commands behave like this with regard to
recusion and the ui.commitsubrepos setting:

          | recurses      | recurses
          | by default    | with --subrepos
  --------+---------------+----------------
  commit: | commitsubrepo | True
  status: | False         | True
  diff:   | False         | True

By changing the default from True to False, the table becomes
consistent in the two columns:

* without --subrepos on the command line, commit will abort if a
  subrepo is dirty and status/diff wont show changes inside subrepos.

* with --subrepos, all three commands will recurse.

A --subrepos flag on the command line overrides the config settin.g

  $ "$TESTDIR/hghave" svn || exit 80

  $ fix_path()
  > {
  >     tr '\\' /
  > }

SVN wants all paths to start with a slash. Unfortunately, Windows ones
don't. Handle that.

  $ escapedwd=`pwd | fix_path`

are unknown directories being replaced by tracked ones (happens with rebase).

Modify one of the externals to point to a different path so we can
test having obstructions when switching branches on checkout:
  $ hg checkout tip
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo "obstruct =        [svn]       $SVNREPO/externals" >> .hgsub
  $ svn co -r5 --quiet "$SVNREPO"/externals obstruct
  $ hg commit -m 'Start making obstructed wc'
  committing subrepository obstruct
  $ hg book other
  $ hg co -r 'p1(tip)'
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo "obstruct =        [svn]       $SVNREPO/src" >> .hgsub
  $ svn co -r5 --quiet "$SVNREPO"/src obstruct
  $ hg commit -m 'Other branch which will be obstructed'
  committing subrepository obstruct
  created new head

Switching back to the head where we have another path mapped to the
same subrepo should work if the subrepo is clean.
  $ hg co other
  A    $TESTTMP/rebaserepo/obstruct/other
  Checked out revision 1.
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved

This is surprising, but is also correct based on the current code:
  $ echo "updating should (maybe) fail" > obstruct/other
  $ hg co tip
  abort: crosses branches (merge branches or use --clean to discard changes)
  [255]

Point to a Subversion branch which has since been deleted and recreated
First, create that condition in the repository.
