Move the call to LLSpashScreen::hide() to the point where we show the main window.

I gave lynx a bad review. :( I didn't know about the setting FirstLoginThisInstall.
I'm backing out lynx's change, then re-fixing EXT-4237.

Previously any login attempt, even a failed one, would cause the Start
Up pulldown to appear. Now only a successful login will cause this to
happen. Also renamed the setting FirstRunThisInstall to the more accurate
HadFirstSuccessfulLogin (and inverted its logic).

-- Further instrumentation of idle update
-- Removed mActiveQ from LLPipeline, instead making calm objects static during LLVOVolume::idleUpdate
-- Further instrumentation of flexible object update
-- Converted LLDynamicArray and LLMap members of LLViewerObjectList to stl counterparts
-- Increased number of update bins in LLViewerObjectList from 16 to 128 (objects will be processed every 128 frames instead of every 16, or ~ 90% fewer objects processed per frame)
-- Removed unused "renderObjectsForSelect" code.
-- Reenabled LOD updates for objects further than 24m from camera

fixed EXT-4187 "X" does not close client after idle timeout / log off when "Confirm before I quit" is enabled

Next step is to actually implement the OS-specific calls to do so.
Until then, behavior is the same; the status bar will mute/unmute
the "master" audio for the viewer *only*

Introduce static LLCurl SSL verification flag, default 'true', accessed by
LLCurl::setSSLVerify() and getSSLVerify().
Make LLCurl::Easy::prepRequest() check LLCurl::getSSLVerify() instead of
unconditionally setting CURLOPT_SSL_VERIFYPEER 'true'. Also set
CURLOPT_SSL_VERIFYHOST to match.
Make LLXMLRPCTransaction::Impl::init() examine LLCurl::getSSLVerify(), instead
of directly examining gSavedSettings.getBOOL("NoVerifySSLCert").
Make LLURLRequest::checkRootCertificate() set CURLOPT_SSL_VERIFYHOST as well
as CURLOPT_SSL_VERIFYPEER.
Make request() in llhttpclient.cpp (used by LLHTTPClient::getByteRange(),
head(), get(), getHeaderOnly(), put(), post(), postRaw(), postFile(), del(),
move()) pass LLCurl::getSSLVerify() to checkRootCertificate(), rather than
constant 'true'.
Make LLAppViewer::mainLoop() call
    LLCurl::setSSLVerify(! gSavedSettings.getBOOL("NoVerifySSLCert"))
at the same time it calls LLCurl::setCAFile(), a comparable bit of static
setup.

EXT-4470 Several bad assumptions that LL_PATH_PER_SL_ACCOUNT is always good (which it isn't until after login)

Of the four options suggested in the jira, this is a modified version of #2.  Since the mime_types.xml file actually gets localized (it contains a bunch of user-visible text in addition to the mappings), I don't think renaming it in viewer_manifest.py will work.

Instead, I've created additional files (mime_types_linux.xml and mime_types_mac.xml) in the same location, and changed the code that loads the file in LLAppViewer::init() to look for different names per-platform.

I'm sure there are cleverer solutions (such as abusing the translation xml overlay system to create files that have deltas per platform), but those don't fit in the time-box allocated to this issue.

Renamed llviewerversion to llversioninfo, to avoid confusion with
llversionviewer in llcommon (llversion is already used by llwindow).

Created new LLVersionInfo class with the following methods:

        static S32 getMajor();
        static S32 getMinor();
        static S32 getPatch();
        static S32 getBuild();
        static const std::string &getVersion();
        static const std::string &getShortVersion();
        static const std::string &getChannel();

All viewer code has been updated to use this API. Viewer code no
longer directly includes llversionviewer.h from llcommon.

This module now contains general viewer version routines, not just
access to the viewer build number, so I've renamed it from
llviewerbuild to llviewerversion.

Rather than copy/paste the same version string formatting pattern
again, I added new string-based version routines:

/// return the full viewer version as a string like "2.0.0.200030"
const std::string &llGetViewerVersion();

/// return the viewer version as a string like "2.0.0"
const std::string &llGetViewerShortVersion();

/// return the viewer build version as a string, e.g., "200130"
const std::string &llGetViewerBuildVersion();

Changed an assert to an llerrs with extra info
Added "HTTP Textures" to "Develop" menu

Review #49

This change adjusts each media's priority based on whether the viewer is minimized (media priority becomes HIDDEN) or unfocused (media priority becomes LOW). However, due to the fact that updateMedia() was no longer being called when minimized, I moved its call out of LLViewerTextureList::updateImages() (a seemingly odd place anyway) and into its own idle callback.
