Fix up an issue introduced with [3326] and PySqlite 2.2.0: SQLite patch release number is not an integer. PySQLite > 2.2.0 does not suffer from this trouble.

PermissionPolicy: Added `PermissionSystem.expand_actions()` utility method,
useful for plugins, fixed a bug in the permission caching layer, and security
polices must now be explicitly defined in the configuration file to be used.

Avoid the {{{LIKE %s ESCAPE}}} syntax if the database is sqlite < 3.1. Closes #2960.

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.
