7b3bd45cfe or_connection_t: replace real_addr with canonical_orport.
Instead of replacing connection_t.{addr,port} with a canonical
orport, and tracking the truth in real_addr, we now leave
connection_t.addr alone, and put the canonical address in
canonical_orport.

Closes #40042

Closes #33898

15860c8846 addr: Use tor_addr_t instead of uint32_t for IPv4
This changes a LOT of code but in the end, behavior is the same.
Unfortunately, many functions had to be changed to accomodate but in majority
of cases, to become simpler.

Functions are also removed specifically those that were there to convert an
IPv4 as a host format to a tor_addr_t. Those are not needed anymore.

The IPv4 address field has been standardized to "ipv4_addr", the ORPort to
"ipv4_orport" (currently IPv6 uses ipv6_orport) and DirPort to "ipv4_dirport".

This is related to Sponsor 55 work that adds IPv6 support for relays and this
work is needed in order to have a common interface between IPv4 and IPv6.

Closes #40043.

a81827d99f Make channel_get_addr_if_possible() take a const channel_t.
(There is no reason that looking up the address of a channel should
ever change it.)

894ff2dc84 dos: Pass transport name on new client connection
For a bridge configured with a pluggable transport, the transport name is
used, with the IP address, for the GeoIP client cache entry.

However, the DoS subsystem was not aware of it and always passing NULL when
doing a lookup into the GeoIP cache.

This resulted in bridges with a PT are never able to apply DoS defenses for
newly created connections.

Fixes #33491

f403af2207 Split geoip from geoip-related stats.
This commit just moves the code to two separate files. The geoip
code still has a few needless dependencies on core/* and features/*.
