I've already implemented validation for Request API [1]. There is only
validation for certain fields - if certain field needs another's one
content for validation, it may just looks for it (see
pidgin_dialogs_im_name_validator).

To try this out, call buddies -> new instant message (Gadu-Gadu
protocol supports only number-based usernames, while xmpp supports
alphanumeric).

Please comment.
