pull: add --remote-hidden option and pass it through peer creation

This option will allow to pull changesets that are hidden on the remote. This
is useful when looking into a changeset’s evolution history, resolving
evolution instability or mirroring a repository.

The option is best effort and will only affect the pull when it can. The option
will be ignored when it cannot be honored.

Support for each type of peer is yet to be implemented. They currently all warn
about lack of support. The warning code will get removed as peers gain
support for this option.

The option is still experimental, so we will have freedom to update the UI or
implementation before it graduates out of experimental.

Based on a changeset by Pierre-Yves David, which added the option.

Test case where subversion would fail to update the subrepo because there
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]       $SVNREPOURL/externals" >> .hgsub
  $ svn co -r5 --quiet "$SVNREPOURL"/externals obstruct
  $ hg commit -m 'Start making obstructed working copy'
  $ hg book other
  $ hg co -r 'p1(tip)'
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (leaving bookmark other)
  $ echo "obstruct =        [svn]       $SVNREPOURL/src" >> .hgsub
  $ svn co -r5 --quiet "$SVNREPOURL"/src obstruct
  $ hg commit -m 'Other branch which will be obstructed'
  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    *obstruct/other (glob)
  Checked out revision 1.
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (activating bookmark other)

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

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