The enable or purge operation of an extension could take a long time if an
expensive operation needs to be executed on a large set of data. To allow
this to succeed from a web interface with max_execution_time set in the
webserver's php configuration, subsequent requests must continue the
operation started earlier. So individual enable and purge implementations
must be able to spread their work across multiple steps.

The base class for captcha plugins has been renamed, but the old name continues
to exist as an empty subclass of it for backwards compatability.

To avoid large bc breaking changes, modules in the old includes directory
structure still follow the same naming conventions. Modules in extensions
have to be placed in an xcp/ folder and need a _module suffix. The
corresponding info file is in the same directory but with an _info suffix.

Search backends are now required to be autoloadable. The database updater to
3.1 tries to guess the class name as phpbb_search_<oldname> which works for
the default backends we ship.

As a consequence currently all stylesheets will be served through style.php
(with no caching) until imagesets are removed [PHPBB3-10336], then
they can we served as static files by HTTPd.
PHPBB3-9741
