f89227fc1a Remove mutex lock on realizeTechniques 
This was causing a deadlock - and I can't quite remember what problem it was intended to solve so it is best to remove it.

706ab387de Add reporting callback option to SimGear 
Allows us to trigger an error logging callback explicitly, which can
be used to drive Sentry.io on the FlightGear side.

cddfdb7d1d TerraSync: stronger fix for handling 0-byte files 
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.

46f4967f6e Allow use of old zlib-1.2.3 on OpenBSD. 
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.

exists, instead of proving the server via a 404. This reduces the
number of requests we make considerably, which is … important.

ec3829addb TerraSync: validate local dirs incrementally

1568ed8b97 Catalog migration: migrate packages too 
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.
