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.
Trying to fix a reported crash, in this code. malloc() returning null
seems unlikely but worth checking for. ALso use a unique_ptr with
a custom deleter to avoid a leak if we throw.

If TerraSync/Airports is missing, download Airport_archive.tgz instead.
In all other cases update as normal. This has the effect, that fresh
installs make many fewer requests to TerraSync servers.
Re-add (with some tweaks) the persistent tile-cache code, so that
TerraSync checks the server at most once per 24 hour period, for a
given repository path.
(Disbale the cache by setting /sim/terrasync/enable-persistent-cache=0)
Avoids need to specify the 3rd-party dir, in the standard/fgmeta
layout of source directories, and accept more combinations of path,
when the user specifies a value.
Previous additional checks for a value BUILDING_LIST entry
used an enum incorrectly, resulting in all BUILDING_LIST entries
failing. Now fixed to check bad() / fail() which are bool.
New log-level to avoid using ‘ALERT’ for expected mandatory messages,
since I want to do error collection on real alerts in a future commit.
As part of this, split logstream.hxx into separate header files, and
add a new virtual hook to LogCallback which takes the complete log-entry
