Use `req` in the few remaining `wiki_to_oneliner` calls. Fixes #4138.

0.10-stable branch: Ported fix r4243 to 0.10-stable, fixes #4122.

Disable form token validation if the content-type is text/xml. This
fixes #4122.

Added an `export:<rev>:<path>` TracLinks for getting access to files in the repository using the raw format.

This goes together with a new URL format `/export/<rev>/<path>`, which is especially useful for browsing HTML documents stored in the repository and getting the relative links (embedded images, stylesheets, etc.) to work as expected.

Also, this interacts better with IExplorer (fixes #3083).

WorkFlow: Merged [4092:4240/trunk]

WebAdmin: applied steffenp's patch which fixes a few syntax errors in Clearsilver template. Closes #4134.

TracQuery supports specifying lists of ids (fixes #4119)

The `ticket:` TracLinks has been extended so that one can specify lists (and even ranges) of tickets, e.g. `#12,23-34,35,36,50,40-42` (see #3011).

This works with the TicketQuery as well (#2604). However, in this context the tickets and ranges have to be separated by the "|" character, as the "," character is already used as an argument separator.

Example:
{{{
[[TicketQuery(group=type&id=12|23-36|40-42|50,format=table)]]
}}}

In addition, the "!" negation operator works also for such lists.

A few more fixes for compliance with [Genshi 421]

Make it possible to reuse the regexp string for ranges.

Some enhancements and bugfixes for the Ranges class contributed by Tim Hatch.

> ... I went ahead and added a `__str__` method that will return the most compact representation of the range so it could be used in links. It also has a few bugfixes:

* big-to-little ranges would throw an exception, but only if all were big-to-little
* certain overlapping pairs would cause weird internal representations which were nonoptimal
* a and b were not set for empty ranges, causing an !AttributeError on any `__contains__` call

Use the above to provide compact ranges representation for log: hrefs.
