In order to transition smoothly, maek resolve_my_address_v4() call the new
fancy find_my_address() with AF_INET.
Next commits should remove the use of resolve_my_address_v4() accross the code
to use find_my_address().
This commit is so the unit tests would be more easily fixed and port to the
new find_my_address() internals.
Part of #33233.

resolve_my_address() was beyond repair in terms of refactoring. Way too
complex and doing too many things.
This commit implements find_my_address() which in theory does the same as
resolve_my_address() but in a more clean, concise and modern way using the
tor_addr_t interface and for multiple address family.
The caller needs to pass the address family (IPv4 or IPv6) which this
interface supports. For both, a last resolved cache is used as well.
Implements #33233

With prop312, we want to support IPv4 and IPv6 thus multiple Address statement
(up to 2) will be accepted.
For this, "Address" option becomes a LINELIST so we can properly process the
IPv4 or/and IPv6.

Since Tor 0.2.9 has been unsupported since January, 0.3.5 is the
oldest supported version, and its features constitute the oldest
recommended feature-set.
This patch updates these recommendations:
DirCache=2
Support for consensus diffs.
New in 0.3.1.1-alpha.
HSDir=2
Support for v3 onion service descriptors.
New in 0.3.0.4-alpha.
HSIntro=4
Support for Ed25519 intropoint authentication keys.
New in 0.3.0-4-alpha.
HSRend=2
Support for rendezvous cells longer than 20 bytes.
New in 0.2.9.4-alpha.
Link=5
Link padding and link padding negotiation.
New in 0.3.3.2-alpha.
LinkAuth=3
Ed25519 link authentication.
New in 0.3.0.1-alpha.
This tracking of the instantiation count should eliminate race conditions due
to starting and stopping machines rapidly. Now, we should no longer obey
STOP commands for previous machines.
This field area was memset to 0 in old versions, which the code treats as
"match any machine instance", for backward compatibility without a protover
bump.
