[Voice Update] Further sync llvoiceclient and llvoicevivox with upstream

Mainly tiny motions to ease merging as viewer-vivox2 work continues
Condenses MultiVoice block
Let shaders dictate vertex buffer attributes for alpha faces (if shaders are enabled)
Experimental volume face batching changes (Cursory testing shows: +~10% larger mean batch size).
-Drive pass selection by face pools. Doing such removes a fair bit of redundant (and often buggy) code.
-Ignore irrelivant batch breakers depending on pass/pool type.
-Face sorting algorithm modified to potentially allow larger batches.
-Removed a few unused/broken things (bake_sunlight/no_materials)
-Fullbright handling should hopefully be a little more consistent.
-Prevent fullbright faces from being placed in 'simple' pool. (They are already simple-er)

Fixed attribute error that popped up with bump faces when batching was disabled.
Added missing can_batch_texture check. Fixes unbatchable faces occasionally getting batched with the last batchable face batch. This was mostly noticeable with animated faces.

Fix poor batching with mac/ancient drivers. Also, some minor tweaks to sorting algorithm.
Merge branch 'master' of git://github.com/Shyotl/SingularityViewer
Fixed an artifact of Root->Avatar Center rename (Sappadilli)
Update qtoolalign (Fixes issue 704)

- Removes shortcut ctrl-a for align tool
-- to avoid ctrl-a for select all text in UI controls messing up prim selection
- Adds llselectmgr select all function
-- to replace ctrl-a select all prims functionality that was a side effect of qtoolalign having this shortcut
- Adds toggle button (up/down arrow) to build floater for toggling display of the lower tab container area
-- This is to satisfy users who relied on ctrl-a to use align while the build floater was minimized and out of the way
- Syncs qtoolalign from Alchemy

[Voice Update] Update SLVoice prebuilds and packaging script
[Voice Update] Sync default voice debug level with upstream.
[RLVa] Updates thanks to Kitty

1ea7389, 49be412, ed4c8e6 & 7ce9521
- changed : "Give to #RLV" agent-to-agent and script-to-agent offers can contain subfolders
-> limited to 3 levels (e.g. #RLV/~FolderA/FolderB/FolderC)
-> #RLV folder is auto-created if it doesn't currently exist

8780d84 - Incremented version number to RLVa-1.4.10
f078067 - internal : boolean (custom) debug settings should have a boolean type
72a8ad8 & 401ca14 - internal : added supporting code for "Detach Folder" RLVa lock checks

05718b5
- fixed : RenderResolutionDivisor is non-functional
-> RenderResolutionDivisor isn't actually taken into account when checking the new screen resolution against the current screen buffer size

4fa138b
- fixed : viewer clips mouse to its rectangle when switching into mouselook while it's not the active application
-> Repro:
* rez a prim with a script to llForceMouseLook(TRUE) and force-sit when clicked (with a slight delay)
* click the prim and give focus to another application
=> the viewer will center the mouse cursor on itself and restrict movement to within its own rectangle (requires alt-tab to escape)
+ Singu Note: Thanks to Kitty for this, it is possible that this would happen in our last release

14132c9
- fixed : region name and global coordinates are shown on the About floater when @showloc restricted
+ Singu Note: RLV version is now shown in help->about

9a2af62 - changed : llRegionSayTo messages are no longer subject to @recvchat(from) or @recvemote(from)

2dc4b89
- fixed : @getstatus and @getstatusall should specify an (optional) separator
-> added support for both @getstatus:tp;|=123 and @getstatus:;|=123

fbb3fb1 - Incremented API version number to 2.8.0
92c39b9 - internal : quick and dirty hack fix for RlvUtil::filterNames() but there's no time to do a proper backport from RLVa-1.5
2580f1c - internal : remove hack for legacy viewers without multi-attachment support
