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.
