Check the return value of fscanf() instead of relying on feof(). This
should help ensure that we exit correctly.

This feature was removed in v2.5.1rc0-427-gf529ab5d0a, anticipating that
MaxMind would remove support for it in 2019. They have however changed
their mind and maintained latitude and longitude information.
They recommend displaying an accuracy radius, but the reported values
are 50, 100, 200 and 1000km. When implemented literally, a marker in
Ireland would cover the whole island plus mainland, so I have instead
opted to use a fixed radius of 1km at deeper zoom levels.
The old ipmap.html file was outdated and had broken tiles, I rewrote a
new one from scratch using the light-weight Leaflet library combined
with tiles from OpenStreetMap. This is more mobile-friendly and secure
(https, SRI). To improve handling of nearby or overlapping nodes,
clustering is used (individual nodes can still be inspected).
Browser compatibility results: IE8 is unusable, IE9 partially works
(tooltips sometimes disappear and the cluster radius control is gone),
IE11 works. Of course Firefox 65 and Chromium 72 have no issues.
The map popup description in the generated GeoJSON structure is now
split in several properties, allowing presentation to be handled by the
HTML page instead of the C code.

It's possible to block while we're writing to our mmdbresolve pipe,
particularly on Windows. Move the write to a separate thread.
Add an #ifdef to mmdbresolve.c which helps test blocking.

It's not just worrying about the lack of a check for a null return, it's
worried about the leak. Assign the result to a different variable and,
if the result is null, free the old data before exiting, and if it's not
null, assign the new variable to the one we're using as a pointer to the
array.

Unlikely, but not impossible, and should squelch a VS Code Analyzer

Visual Studio doesn't ship with a getopt implementation, so process our
arguments ourselves. Note that if we add support for more flags we'll
probably want to use GOption.

MaxMind is discontinuing its legacy databases in April in favor of
GeoIP2, which use a newer database format (MaxMind DB). The reference C
library (libmaxminddb) is available under the Apache 2.0 license which
isn't quite compatible with ours.
Add mmdbresolve, a utility that reads IPv4 and IPv6 addresses on stdin
and prints resolved information on stdout. Place it under a liberal
license (MIT) so that we can keep libmaxminddb at arm's length. Add
epan/maxmind_db.[ch], which spawns mmdbresolve and communicates with it
via stdio.
Migrate the preferences and documentation to MaxMindDB.
Change the IPv4 and IPv6 asnum fields to FT_UINT32s. Change the
geographic coordinate fields to FT_DOUBLEs.
