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.
Candidate for 2020.X
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.
When doing a catalog migration to a new ID (eg, 2018 -> 2020), also
mark the installed packages for installation, on the new catalog.
Related to this, when manually removing a catalog, record this fact,
so we don’t re-add it automatically due to migration.
Add unit-tests covering both of these cases.
