PermissionPolicy: Apply permissions to attachment HDF.

Merged [3264:3323/trunk]. Starting point for the new cache.

Make the display of the changeset file details in the Timeline consistent with the one of the Changeset view. Closes #2466.

Use html utils to format Changeset links. Closes #3166.

TracRevisionLog TracLinks improvements:
* added restricted log range syntax (e.g [3000:3300/sandbox],
the log between 3300 and 3000 concerning the sandbox)
* added InterTrac shorthand syntax for the log ranges
(e.g. [trac 3000:3300] or even [trac 3000:3300/sandbox])

Introduced ''citation'' syntax for the Wiki, e-mail style.
Each leading ">" character introduces a new level of citation.

This reuses most of the machinery introduced previously
for a more robust handling of blockquotes.

However, note that in the case of citations, the ''depth''
of a blockquote corresponds stricly to the number of leading
">" characters.

Follow-up to r3314, use `to_unicode()` instead of `unicode()`, as `text` can actually be some `str` provided by a pre-unicode user macro.

Robust coupling of Wiki lists and Wiki quotes

With [3316], new indent levels are only introduced when they need to be.

However, the implicit relationship that existed between the
indentation level of the lists and the indentation level of the blocks
was lost.

We therefore keep track of the indentation level introduced by
either of them, referred to as "tabstops".

That way, the current indentation is remembered even when
empty lines are introduced for clarity, and the appropriate
indenting is used for quotes following lists or quotes:

{{{
* first level
* second level

A second level quote
}}}

Tab characters are now converted before the line is parsed.

Fixes #124.

More robust parsing and formatting of Wiki lists (#124)

Previously, each indent of 2 spaces would introduce a new indentation level.
This lead to a confusing output in a variety of situations,
especially in changelog style commit messages.

Now, new indent levels are only introduced when they need to be,
i.e. when there's actually a new indented list or paragraph:

{{{
* first level
* second level
- third level

First level
Second level
}}}

Note that a tab character is converted to 8 space characters
before computing the indentation level.

In addition, lists can now also be started using "-" (as this is commonly found
in changelogs as well).

There will be a follow-up changeset focused on the interaction between lists and quotes.
