Remove a log statement from r8436

TracMercurial for 0.12: tweaks for `MercurialRepository.get_path_url`
- if a revision is specified, retrieve the corresponding branch name and use that for the clone URL
- only show the ''Repository URL'' when browsing the repository root
- kept previous link to the matching location in hg's own browser as a comment, in case someone finds that useful (+ fix for posixpath)

Changes suggested by Remy Blank in #1781.

TracMercurial for 0.12 (or MultiRepos, rather): add `get_path_url` in order to support display of ''Repository URL'' contextual navigation links in the repository browser (see #1781)

MultiRepos: Removed `[trac] repository_url` again (introduced in [8431]), as the same effect can be achieved by defining the default repository in `[repositories]` or in the DB.

Related to #1781.

MultiRepos: Avoid issues when copy/pasting repository paths in the repository admin panel. Indeed, the browser includes zero-width and non-breaking spaces in the operation, and this leads to a strange error messaage saying that "<path> is not a valid repository" when it actually is.

MultiRepos: A few small fixes in repository management:

* Fixed an issue with repository URL editing.
* Allow creating an alias as the default repository.
* Fixed an issue when changing an alias to point to the default repository.
* Allow the default repository to be provided by any `IRepositoryProvider`.

MultiRepos: Add the repository URL to the repository metadata and display the link in the source browser.

Closes #1781.

0.12dev: Fixed a regression on Python 2.4 introduced in [8421] (missing import of `any`).

0.12dev: Update the wiki page text in the model ''before'' validation, so that the validation code has access to both the old text (in `.old_text`) and the new text (in `.text`).

Closes #7731.

MultiRepos: merge remaining changes from 0.12dev
