/** ban_check_mask - Checks if the current user in ban checking (ban_ip, etc) matches the specified n!u@h mask -or- run an extended ban.
* @param sptr Client to check (can be remote client)
* @param chptr Channel to check
* @param banstr Mask string to check user
* @param type Type of ban to check for (BANCHK_*)
* @param no_extbans 0 to check extbans, nonzero to disable extban checking.
* @returns Nonzero if the mask/extban succeeds. Zero if it doesn't.
* @comments This is basically extracting the mask and extban check from is_banned_with_nick, but with being a bit more strict in what an extban is.
* Strange things could happen if this is called outside standard ban checking.
