Minor bugfixes for a line in viewer_manifest that never gets run (because of the way the SConstruct file on Linux is built).  However, it might get run in the future, so there we go.  Thanks cg for finding this.  Not reviewed.

Added much more error-recovery logic to template-verifier -- e.g. it retries a few times to fetch the master from the web.  Also I changed the master to live in the system global tempdir, mostly because the build machines had a network problem and I wanted to reduce the chance of that happening.  Not reviewed, but I'm checking it in over the weekend so I can silently fix it if there's yet another weird configuration difference that breaks it on the build machines.

Fixed cache invalidation in simulator.cpp, llsd.php, added RFC 1123 compliant date format, and unit test for the new date function

SL-49406: template_verifier.py requires network access to build.  Implemented a 4-hour cache so it hits the network less often overall (saving approx .5 seconds every build), and added fault tolerance for when it fails to fetch the master over the network.  It'll whine at you if it can't fetch it, but even if it can't get the master from the network and doesn't have a cached copy at all, it will still at least do a syntax check on the local template.

* WARNING *:  maintenance r64837 is not the last rev to use in the next merge. use r65269

Replaced usage of urlopen.read(), which isn't guaranteed to return all of the downloaded bytes, with urlopen.readlines(), which (I believe) does have that guarantee.  This should fix the rash of mysteriously-failing prebuilds.  In the process, added some better error messaging about whether the local template has the parse error, or the master on the network.  Also some reorganization.  Reviewed by Tess and Leyla.

SL-47720 Crash on startup due to SSE instructions.  Disable SSE code generation on Windows build.  This prevents global constants from being initialized with SSE instructions.  We can use the SSE code on Intel Mac (since they all support SSE) and if we enable SSE compilation for the entire Windows viewer.  Reviewed by Kelly.

Fixed broken Mac universal build due to missing files and bad LL_VECTORIZE ifdef for sse-skinning code.

svn merge -r 62595:62596 and 62598:63308 sse-skinning-3 for faster software avatar rendering.  Visual Studio 2005 project file fixed pending.
