BulletSim: rework LinksetCompound to work with new BSShape system.
Not all working yet.
BulletSim: fix crash when mesh asset wasn't available when meshing
the first time.
Debugging added for mesh/hull asset fetch.
Make default config directory "."
Merge branch 'master' into bulletsim4
BulletSim: Rebuild physical body if physical shape changes for mesh and hull.
Properly rebuilds collision caches.
Release asset data fetched when building mesh or hulls.
BulletSim: prims with no cuts created with single convex hull shape.
Parameter added to enable/disable this feature.
On startup, start scenes after we're set up all local scenes, rather than starting scenes before others have been created.

This aims to avoid a race condition where scenes could look to inform neighbours that they were up before those neighbours had been created.

Fix possible race condition with local region cache if a region was added after startup.
BulletSim: zero vehicle motion when changing vehicle type.
Rebuild compound linkset of any child in the linkset changes shape.
Comments and better detailed logging messages.

Minor reordering of operations on NewUserConnection. The agent circuit needs to be added earlier for some of the checks to work correctly.

Added new method to Remote Admin for reloading the estate settings. This is meant to be called when some other program has changed the data on the backend.
BulletSim: extend BSActorLockAxis to allow locking linear movement in
addition to angular movement. Not enabled by anything yet.
BulletSim: simplify parameter specification by reducing the number of
specifications required for simple properties with defaults.
BulletSim: remove friction calcuation from BSMotor and move linear and
angular friction computation into linear and angular movement code.
The friction wasn't being applied properly. This will make it so vehicles
don't drift as much and the drift is tunable by changing the friction
timescales.
BulletSim: apply linear and angular friction in vehicle coordinates
and not world coordinates.
Step one of estate settings sharing - port the Avination Estate module (complete module) as changes are too extensive to apply manually
Step 2: commit the IEstateModuleInterface changes needed
