=head2 callback
Takes hash with optional C<CallbackPage>, C<CallbackName>
and C<CallbackOnce> arguments, other arguments are passed
through to callback components.
=over 4
=item CallbackPage
Page path relative to the root, leading slash is mandatory.
By default is equal to path of the caller component.
=item CallbackName
Name of the callback. C<Default> is used unless specified.
=item CallbackOnce
By default is false, otherwise runs callbacks only once per
process of the server. Such callbacks can be used to fill
structures.
=back
Searches for callback components in
F<< /Callbacks/<any dir>/CallbackPage/CallbackName >>, for
example F</Callbacks/MyExtension/autohandler/Default> would
be called as default callback for F</autohandler>.

=head2 request_path
Returns path of the request.
Very close to C<< $m->request_comp->path >>, but if called in a dhandler returns
path of the request without dhandler name, but with dhandler arguments instead.

Logs any recorded SQL statements for this request before calling the standard
abort.
