WIP: critical bug EXT-4837 ([NUX] When filter results in null state, provide a message suggesting the user try global search.)

Partial implementation of help text in case of empty list when filtered for Nearby and Recent lists of People panel:
 * Extracted support implementation of several messages for empty list depend of filtering from LLGroupList to LLFlatListEx
 * change inheritence of LLGroupList and LLAvatarList from LLFlatListView to LLFlatListViewEx
 * updated panel people to init Nearby & Recent lists with appropriate messages.

--HG--
branch : product-engine

* Implementation notes:
** special item is cloned from VCP to be used in LLAvatarList to reflect an Avaline caller.
** LLAvatarList extended to create instances of Avaline Caller
** Participant list now determines type of adding session participant (Avatar/Avaline Caller) and selects a way item will be created in avatar list

* Implementation behavior:
** The problem is when Avaline caller ends a call it is removed from Voice Client session but
   still exists in LLSpeakerMgr. Server does not send such information.
   HUCK was implemented to notify subscribers that Avaline callers are not anymore in the voice call.
** For now Avaline Caller is removed from the LLSpeakerMgr List when it is removed from the Voice Client session.
   This happens in two cases: if Avaline Caller ends call itself or if Resident ends group call.

** If Resident joins group call where Avaline caller already exists that caller will appear in Resident's viewer (VCP & Group IM window)
** The callers are displayed as "AvaLine Caller 1", "AvaLine Caller 2" etc.

* Known issues:
** LLNonAvatarCaller should be removed from VCP (for avaline p2p calls). Updated Avatar & Participant Lists can be used instead of it.
    Separate ticket will be opened to refactor this code.

Fixed some more typedefs that I missed in first checkin.

Superficial cleanup to change all typedef std::vector<LLUUID> to use a common typedef uuid_vec_t instead.

added requesting a list to resort when avatar list item gets updated with avatar name from the name cache

--HG--
branch : product-engine

Cause:
Avatarlist has been hidden before it had been updated. So one listitem was left in the list and  remained always selected.
Solution:
Force update ability has been added to avatarlist

-- refactored processing of voice participants in the "Voice control panel".
  Now list is filled only when voice channel is in CONNECTED state and is cleared otherwise.

--HG--
branch : product-engine

Fixed normal priority bug EXT-3677 (Resident doesn't appear in the nearby voice list after enabling voice).
 * Avatars having voice chat disabled will not be displayed in the voice control panel.
 * If an avatar disables and then re-enables voice chat, it will re-appear in the VCP.
 * Avatars that are not in the nearby chat range anymore, will be immediately removed from the VCP
   (were displayed in italic for a few seconds).
