Allow the helper function call_hook() of class phpbb_template to be called
from more than once location and thus for more than one hook (although there is
only one) by adding the method name as a parameter.

This commit adds a template path provider to separate the process of locating
(cached) paths in extensions from the template engine. The locator is supplied
with a list of paths from the path provider.
Admin templates can now be created in ext/<ext>/adm/style/ and regular
templates go into ext/<ext>/styles/<style>/template/. Extension templates
override regular templates. So if an extension supplies a file with a name
used in phpBB, the extension's file will be used.
A side-effect of this commit: Locator and Provider are now able to deal with
arbitrary levels of template inheritance. So we can expose this through
phpbb_template if we choose to, and allow styles to inherit from inherited
styles.

The origins of orig_tpl_* are not pretty. Please see the following commits
and associated tickets: r9823, r9839, r9847, r10150, r10460.
In short, multiple hacks were required due to template engine reading
inheritance/storedb flags from $user (global) even when the template that
was being looked up or rendered was not the "active style of the
current user".
We no longer store templates in the database, removing half of the problem.
This commit fixes the second half of the problem by deleting
set_template_path function from template locator, and moving that logic
back into the template class' set_template. set_template now calls
set_custom_template, the latter only taking the template path and the
fallback paths as parameters. With this change template locator no longer
uses $user and does not use phpbb root path either.
All logic involving setting the user's "active" template is now
encapsulated in a single template class's function, set_template.
Setting other templates is done via set_custom_template and the caller
is responsible for determining and passing in fallback/inheritance path,
if any.

Template locator is responsible for maintaining mapping from template
handles to filenames and paths, and provides resolution services
using these mappings.
Template locator is aware of template inheritance and is capable of
checking template file existence on the filesystem.

This seems to have been used for db storage of templates.
We no longer offer db storage of templates, and thus currenty
$files_template is only written to but not read anywhere.

The template stream filter no longer depends on the $config global.
Instead it uses a 'allow_php' param that is passed via
stream_bucket_append's last argument.
Tests also adjusted.
