Lock m_UserCache whilst iterating over it in UserManagementModule.GetUserData() to avoid concurrency exceptions
Log when "Unknown User" is sent to a user because the UMM had no binding for that UUID and when a binding replaces a previous "Unknown User" entry.

This is a temporary measure to hunt down issues where some but not all users see others as "Unknown user" in text chat, etc.

Add "show name" console command to make it possible to show a single binding of a UUID to a name.
minor: Change "show names" command to use consistent console display table
Make "show name" command display HomeURL like "show names"
Fix compile failure from recent git master 434c3cf
To further help with tracking down the apperance of too much "Unknown User" in chatlogs, etc. temporarily change each instance of this in OpenSimulator so we can identify where it's coming from

For instance, the "Unknown User" in Util.ParseUniversalUserIdenitifer becaomes "Unknown UserUPUUI (class initials + method initials)
This is to help with http://opensimulator.org/mantis/view.php?id=6625

BulletSim: add gImpact shape type. Add logic to use gImpact shape
for prims that have cuts or holes. Default logic to 'off' as it
needs debugging.
BulletSim: add code to experimentally use asset hull data.
Default to 'off' as it needs debugging.
BulletSim: update DLLs and SOs with version containing gImpact code.
Revert "BulletSim: add code to experimentally use asset hull data."

This reverts commit 2fd8819a043269f9308cb46c71893e6eb35a426e.

Remove this code until I can figure out why the references that are
clearly in prebuild.xml doesn't work for the
'using OpenSim.Region.Physics.Meshing' in BSShape.cs.
Implement llSetSoundQueueing().

This is controlled by the viewer, not the server.
So as per http://wiki.secondlife.com/wiki/LlSetSoundQueueing, only two sounds can be queued per prim.
You probably need to use llPreloadSound() for best results
BulletSim: fix problem with walking up stairs that are oriented
in certain directions. The problem was really that the avatar capsule
orientation was being set incorrectly.
BulletSim: add code to experimentally use asset hull data.
Default to 'off' as it needs debugging.
BulletSim: specify directory for OpenSim.Region.Physics.Meshing
DLL file in prebuild.xml since that file ends up in bin/Physics
directory.
BulletSim: correct errors caused by misspelled INI parameter spec.
Add debugging messages for hull asset use.
