Bram Matthys 172ace9750 geoip_maxmind: use our own mmdb implementation
This is mainly due to licensing. The libmaxminddb library uses the
Apache license, which meant if we would compile it in by default it
would effectively transform our "GPLv2 or later" to "GPLv3 or later".
Our implementation is ISC licensed, so we can include and enable it
by default and keep things at "GPLv2 or later". This is also why we
used geoip_classic in the first place as default and compiled in,
and not the mmdb variant.

The mmdb.c is based on the specification, using the Go implementation
as a reference during development (ISC licensed), initially implemented
with the help of Claude Opus 4.6. After that substantial changes were
made to make it match UnrealIRCd's style and to make things less error
prone: C style changes, allocation and zero termination of strings in
the library, auto-NULL in variadic functions so the caller cannot
forget NULL there (similar to our unreal_log/do_unreal_log), using
enums as the return type instead of int (similar to curl), adding
doxygen docs, etc.

This also means the old mmdb library dependency has been dropped,
including from configure/autoconf.

At the moment we still use the geoip classic library by default,
including those DB files. The idea is we will switch over sometime
later after this current new MMDB stuff has received more testing.

This also makes us more flexible, since .mmdb files have become the
de-facto standard for pretty much all geoip vendors.
