consolidated most indra-specific constants in llcommon under indra_constants.h
fixed issues with operations on mixed unit types (implicit and explicit)
made LL_INFOS() style macros variadic in order to subsume other logging methods
such as ll_infos
added optional tag output to error recorders

CHUI-675 FIX You can select multiple users in people floater but can only drag and drop one name to conversation
Moved drag and drop start in LLAvatarListItem instead of LLAvatarList, and made LLFloaterIMSession handle multiple dropped participants correctly

CHUI-580 : WIP : Change the display name cache system, deprecating the old protocol and using the cap (People API) whenever available. Still has occurence of Resident as last name to clean up.

- When accepting an avaline call, add a caller to the recent list as AvalineListItem

- When adding item to the LLRecentPeople, check whether item with the same phone number exists and delete it if exists. This is need to avoid duplication in the Recent list of the panel People.

back-out the back-out for this branch.  yay.

Backing out this merge that I pushed (prematurely) to the wrong place.

streamlined LLUICtrlFactory's interface

removed redundant functionality
moved buildPanel to LLPanel

Needs new icon artwork, currently reusing old 1.23 icons.

Note: changes in the llparticipantlist.cpp is a fix of initial implementation in 79c0487c2280 changeset.
    "waiting" is shown instead of phone number.
It was not reproduced before because phone was not shown anywhere until this patch.

Two problems:
1. AvatarList didn't hide popup menu when goes invisible.
2. (Real problem) MenuHolder View didn't process TAB key. Which leads to changing active ("focused") control. Which leads to the ability (for example) to switch tabs and hide popup menu parent view.

- Added accordion tab title highlighting setter and title getter.
- Added filtered tabs title highlighting.
- Tabs which don't pass filter are hidden.
- Added applying filter on list refresh event to avoid refreshing list on every filter change.
- Moved part of LLTextUtil to llui/lluitextutil to reuse code in llaccordionctrltab.
- Fixed passing list size to mRefreshCompleteSignal.
- Added list refresh callback to LLInventoryItemsList for checking tab visibility  without re-applying filter sub-string.

Committed to proceed with dependent tasks.
If there are any comments/suggestions related to text utils this part of code may be changed without requiring much effort.

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

Implemented passing of entered filter substring without head spaces to search URI in help message for null filtered results.
* Updated setting "no item message" to use search term from filter editor for avatar & group lists and for inventory panels.
* Updated appropriate translatable strings to get [SEARCH_TERM] substitution.
* Updated processing of filter substring to pass original string to methods applied new filter.

Additional necessary changes
* Changed place to set "no item message" for group list from refresh to where filter is updated (like in avatar lists)
* Removed converting of filter substring to upper case in Places & My Appearance sidepanels (this conversion has already been implemented in where filter is applied)
* Added a separate message for Landmarks to set search URI to secondlife:///app/search/places for Lanmarks panel;
 other inventory related panels have URL to all searched categories (secondlife:///app/search/all)

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.

* 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.
