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.

e1fe9b45e0 Unzip: adjust error reporting mechanism

837ba86d57 DNSClient: own requests, and cancel them on timeout 
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.

72b2eb0ebf TerraSync: avoid 404s to probe missing tiles 
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.

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.
