Follow-up to r6171: don't use generator syntax, as we still support Python 2.3.

Closes #6376.

Ticket #2048: add `Span` as a synonym for the `span` macro.

Ticket #2048: add some unit tests for the div and span wiki processors.

Ticket #2048: add a `div` and a `span` built-in wiki processors.

The div macro should be used with a block and can be used for wrapping any wiki text (including contained blocks) within a <div> element. The `class` and `style` attributes of the <div> can be specified by listing keyword arguments after the div. The value of such an argument can be quoted using single or double quotes if it has to contain space characters (usually the case for the `style` attribute).

Example:
{{{
{{{
#!div class=important style="background: #ffaaaa"
Note that:
- use with care!
- you have been warned
- I won't repeat it
}}}
}}}

The span macro should be used with the usual macro call style, like ![[span(Note: you have been warned, class=important, style=background:#ffbbbb)]]. Note that the arguments don't support quoting for now.

Ticket #2048: use `re.match` instead of `re.search` for matching the wiki processor specification line

Ticket #2048: refactor trac/wiki/formatter.py to use the genshi tag builder instead of 0.10 compatibility way.

Ticket #2048: add a CSS class named "important", which can be used to highlight some spans or divs like originally illustrated in that ticket.

Fixed corner case in the side-by-side diff rendering template, triggered when the requested number of context lines couldn't be honored on the "changed" side, due to the "ignore blank lines" diff option.

Closes #6015.

AuthzPolicy: simplify the way to identify resource. The pattern matching all versions is implied if not given.

Another follow-up to r5253. Really fix #3808 this time.
