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.

Metar sky condition without base layer height (e.g. FEW///) is the cause of this issue.
Randomize the base layer height when the actual height is unknown.
- scoped locks using lock_guard are better
- because of this the exception handler can also be removed;
although this was originally intended to manage the locks
it never did work properly with C++ exceptions.
Change logic so we create an empty file for such cases, i.e exactly
matching the repository. This simplifies logic in downstream code,
compared with not creating a local file.
Add a test-case to cover this
Modify TerraSync to detect a failure of Airports_archive downloading,
and fall back to file-by-file updating.
Fixes crashes where a request times-out, but then is completed by
UDN sometime afterwards, with a free-d object. Have the DNS::Client own
requests, and be able to retrieve the udns_query to cancel them, in
the timeout case.
Fixes a couple of Sentry reports.
As of 2020-08-01, OpenBSD's system zlib is 1.2.3 which doesn't
have gzoffset(). However we can get away with this by making
gzfilebuf::approxOffset() always return zero.
Avoid a central hash cache becoming enormous, now we use the selective
download scheme for the tile dirs.
Hash name is changed to co-exist with older versions.
Use the top-level dirIndex files to determine if a 1x1 tile dir
exists, instead of proving the server via a 404. This reduces the
number of requests we make considerably, which is … important.
Add a process() method to HTTPRepository, and use this to
incrementally validate subdirs after the .dirIndex is received. This
avoids large pauses of the TerraSync thread, when all of Airports/
is validated at once.
