WLM will be shutdown in March 2013. Skype is the new replacement. But as Skype
uses a different login ID and service, the values in this field are useless.
So we can safely remove the field and the links/functions we create.

This is required so that when migrations are reverted we can check through
all installed migrations and make sure that all dependencies are handled
properly and so that we are only required to load the migrations files
that could be dependent on the ones installed.
I believe in normal proper use the old way might have worked, but in case
something happens and an unrelated migration file is installed, but cannot
be loaded, this makes sure we do not stop everything unless we absolutely
must (one of those files is dependent on something we want to revert).

Returning the set of schema changes allows potentially aggregating to generate
the overall install schema automatically from a set of migrations

[ticket/11301] Guidelines: Add spaces in front and after the / operator.
[ticket/11301] Explicitly cast str offset to int to prevent E_NOTICE on 5.4.
The phpbb_user object might be used for language variables. Pass it as a
function argument to prepare_form_acp() instead of using globals.
PHPBB3-10018
Pass the phpbb_user object to function get_custom_html(). This object is
used in that method. Also fixed incorrect arguments to get_custom_html()
in phpbb_get_avatar().
PHPBB3-10018
Remove the $request property from the phpbb_avatar_driver class and rather
pass it as function argument if it's needed in a function. Currently this
is only the case for the class methods prepare_form() and process_form().
PHPBB3-10018
The `@return` documentation of the `phpbb_extension_interface::disable_step`
method states incorrect that the method returns null, as it returns
false or a state.

The upload avatar driver will now inform the user if insufficient data has
been entered for both remote and local avatar uploads.
The local avatar driver (gallery avatar) will also inform the user if he
didn't select a category and/or file before submitting.
PHPBB3-10018
Although get_user_avatar() is not new, the phpbb prefix was prepended. This
is due to the fact that it was entirely rewritten and is therefore more or
less a completely new function.
