When an effect defines no shader sources, special case this error to
avoid confusing result from SGProgram.
Add error-context for readNode STG loading, so failures inside an
STG can be attributed
Report errors from readWAV, and improve attribution for the
format error (include the file path). As a result, mark the individual
exceptions as dont-report, since we will report higher up.
Ensure the STG absolute path can be propagated to all files triggered
by STG loading, including the delayed files and proxied files. This
allows us to attribute errors to the correct scenery path.
Allow us to pass the current error-context from the main thread
into the osgDB loader thread. This is necessary so we can attribute
AIModel (etc) load problems to the correct source.
Move sg_location member up to the base clase, since it’s potentially
useful in more types.
Allow suppression of the report callback when the exception is thrown
Use an exception rather than polling a flag, for checking errors
during BTG reading. This should allow us to give a correctly
identified error, at exactly the point the read fails.
Fixes an error case where a manual TerraSync server is specified; we
would attempt to use an empty string as the OSM2City server, with
hilarious consequences.

Avoid hard-coding the archive extension, and ensure the extracted
archive directory is not orphaned on update. Finally, use the
literal filename in the .dirindex when computing the hash, rather
than adding a .tgz extension.
Ensure all data members are correctly re-initialzied when doing a reset.
This shoed up as negative ‘bytes downloaded’ counts after a TerraSync
abandon and retry.
Extend our own particle manager to replace the OSG particle system
updater. This fixes thread-safety and also timing (better match to
simulation dt values). We also use weak pointers (observer_ptr in
OSG terminology) to ensure particle systems are released once their
frame is gone.
The 'spin' animation has a strange behaviour:
it pushes a temporary rotation matrix on the transformation stack during
cull traversal, and removes it thereafter.
Thus, the rotation matrix is missing outside of cull traversal, e.g.
when the position of Compositor lights is computed.
The same issue was fixed for the 'rotate' animation by commit
e202d4e4a5
(this mentions broken 'picking' animations as a different manifestation
of the same issue).
Fix this by setting the angle of the persistent SGRotateTransform,
instead of creating a temporary rotation matrix.
Previously attempting to start on an ocean tile with static
models present cause FG to spin on "Loading Scenery".
This was caused by not creating a BVH for an ocean tile in
the specific case where there was STG models, due to a PagedLOD
node being inserted in the scene graph. So
FG never thought the scenery was loaded sufficient to place
the aircraft.
By explicitly creating a BVH for ocean tiles the problem is
fixed.

Traversing a container which is modified causes crashes, take a copy
during traversal for firePackageStatus.
