some spanish language files fixes
Fixed noisemap not binding for the nightvision shader.
Manually vectorized some of the UI vertex operations.
Implemented a hash-map for first-level children of ui elements. First-level child lookups are prolificly abused on a per-frame basis, and a plain old loop with a string comparison each iteraton was somewhat of a hotspot. (The recursive loop after is even more expensive, however)
Avoid several excessive per-frame LLView::getChildView calls by instead caching the results in postBuild. (Added CachedUICtrl, which is basically just a self-nulling pointer to not have to make ui ctors dirtier)
More Media Updates

Further updated llviewermedia
Added sim console.
Cleanup. Removal of dead code. Added/renamed object flag accessors.
Implemented basic 'awareness' of objects flagged as permanent.
Setting socket pair non-blocking
Print all libcurl calls if -DDEBUG_CURLIO. Don't create static lib for cwdebug.

Basically, cmake doesn't support linking static libs into a shared lib.
The correct way is to just specify source files in subdirectories
directly as source files of the shared library. This patch changes that.

Also, after this commit, when DEBUG_CURLIO is defined, every call to
libcurl is printed to llinfos (or to dc::curl when using libcwd).
Bug fix

curl_easy_setopt expects a long int. Before this patch,
uninitialized memory was read, leading to extreme long
time out, instead of the intended disabled time out (so,
in practise this patch has little effect).

This bug was discovered with the previous commit.
Fixeds and ToDones

-Color Fixies-
Fixed Gemini skin not looking as it originally did.
We now use DefaultListText to color all otherwise uncolored text in scroll list cells.
All of our dark skins have been updated to use white here, as dark skins are intended to have white text...
This includes the Dark we ship with.

LLFloaterActiveSpeakers no longer uses hard coded font colors, it uses SpeakersInactive, DefaultListText, and SpeakersGhost.

LLFloaterAvatarList no longer uses hard coded font colors, it uses DefaultListText, RadarTextChatRange, RadarTextShoutRange, and RadarTextDrawDist, in place of previously hard coded font colors
Since the tooltip defines color meaning, these new colors should only be skinned to change shade.

DefaultListText defaults to black; SpeaksInactive, gray(grey4); SpeakersGhost, Red; RadarTextChatRange, Red; RadarTextShoutRange, Yellow(yellow1); RadarTextDrawDist, Green(green2).


-Translation update and fixies-
Partial credit to viewer-development, thanks for hanging onto old strings!  Also, updated to look more like v-d in translated areas.
Punctuation strings can be used quite a lot.  Brought them all in, just in case.

AscentPrefs*:
Drag and Drop points now use CurrentlySetTo, CurrentlyNotSet, AnItemNotOnThisAccount, and NotLoggedIn. (applies, as well, to FloaterAO)
Power User message is now built from PowerUser1, PowerUser2, Unlocked:, PowerUser3, RightClick, PowerUser4 and PowerUser5; this should give translators enough space to explain any tough to translate, and make the message easier to alter in the future, if necessary.

LLCompileQueue:
Now uses translation strings from upstream
Starting, Done, Resetting, Running, and NotRunning in its xml.
CompileQueueTitle, CompileQueueStart, CompileQueueDownloadedCompiling, CompileQueueScriptNotFound, CompileQueueProblemDownloading, CompileQueueInsufficientPermDownload, CompileQueueInsufficientPermFor, CompileQueueUnknownFailure, ResetQueueTitle, ResetQueueStart, NotRunQueueTitle, and NotRunQueueStart from strings.

LLFloaterAvatarList(floater_radar) now uses has_entered, has_left, the_sim, draw_distance, shout_range, and chat_range in its xml for translatable alerts.

LLFloaterLand(floater_about_land) now uses minutes, 1_minute, 1_second, seconds, and remaining from its xml.
LLFloaterLand, LLFolderView, LLPanelDirBrowser now make use of InventoryNoMatchingItems, NoneFound, and Searching in their searches.
LLFolderView was brought closer to v-d in translation.

LLGroupNotify now uses GroupNotifyGroupNotice, GroupNotifySentBy, GroupNotifyAttached, next (also now used by LLNotify), ok, GroupNotifyGroupNotices, GroupNotifyViewPastNotices, GroupNotifyOpenAttachment, and GroupNotifySaveAttachment.

LLInventoryFilter synced with V-D for translation:
Now uses Animations, Calling Cards, Clothing, Gestures, Landmarks, Notecards, Objects, Scripts, Sounds, Textures, Snapshots, No Filters, Since Logoff, and Worn.

LLManipRotate now uses Direction_Forward, Direction_Left, Direction_Right, Direction_Back, Direction_North, Direction_South, Direction_West, Direction_East, Direction_Up, and Direction_Down, like upstream v-d.

LLPanelAvatar(panel_avatar) now uses None string in its xml for when there are no groups, also removed cruft. Though the None has not been showing up for quite some time, anyway...

LLPanelObjectInventory now uses Buy, LoadingContents and NoContents,
however the last two strings did not seem to show up anyway...
thanks to Latif Khalifa, Jean Horten, theGenius Indigo and Cubbi Bearcat for confirming this happens across many different versions and on both Windows and linux(32 and 64).

LLPreviewScript now uses CompileSuccessful, SaveComplete, ObjectOutOfRange, and CompileSuccessfulSaving.

LLScrollingPanelParam now translates Less and More.
Avatar Shape Information strings now used for customize appearance panels.

LLTextureCtrl now uses multiple_textures.

LLToolpie has been updated to use v-d include order and now uses UnmuteAvatar, MuteAvatar, UnmuteObject, and MuteObject2 strings.
LLVOAvatarSelf now uses BodyParts* strings for translation of toolpie entries pertaining to bodyparts.

LLViewerMenuFile now uses UnknownFileExtension, and UploadingCosts.

LLViewerMessage now uses Cancel(also used by LLViewerDisplay), AcquiredItems, Saved_message, IM_autoresponse_sent_item, IM_autoresponded_to, IM_announce_incoming, InvOfferDecline, InvOfferGaveYou, InvOfferOwnedByUnknownUser, InvOfferAnObjectNamed, InvOfferOwnedBy, InvOfferOwnedByUnknownGroup, and InvOfferOwnedByGroup.


-AvatarRadar Update-
AvatarRadar enhanced with code from both Cool VL Viewer and some avian corpse.
e_radar_alert_type has been reworked to allow bitwise usage in the future.

Cool stuff:
gSavedSettings for radar are now CachedControls,
entering boolean is now checked before going into the switchcase,
Style changes, yay C++ style.

Avian Flu:
Distance for shout range corrected to be 96.
handleKeyHere: If the user hits enter with an avatar on the radar selected, focus camera on selected avatar; ctrl-enter, teleport to selected avatar.

Otherwise:
Tiny spelling fixies, and a suggestive comment.
Missing Strings.

Oops.  Customize Floater wants these for like once case...
Added rebake navmesh button. Brought in rest of the underlying navmesh implementation.
Display pathfinding attributes in build floater.
Merge branch 'curlthreading2' into curlthreading3
Merge remote-tracking branch 'upstream/master'
WIP
Typo fix
