The exposed interface is "stats/" thus make the unit tests clear that it is
testing that specific GETINFO command.

New name reflects that the function is only used to compare router addresses
in order to learn if they are in the same network.
The network check is /16 and /32 respectively for IPv4 and IPv6.

This unit tests validates the use of IPv4 _and_ IPv6 together as in multiple
option Address lines both addresses and hostnames.

Replace it by find_my_address() everywhere. This changes many parts of the
code that uses it to use a tor_addr_t instead of a plain uint32_t for IPv4.
Many changes to the unit test to also use the new interface.

Series of changes:
1. Rename function to reflect the namespace of the file.
2. Use the new last resolved cache instead of the unused
last_resolved_addr_v4 (which is also removed in this commit).
3. Make the entire code base use the new resolved_addr_is_local() function.
You will notice that this function uses /24 to differentiate subnets where the
rest of tor uses /16 (including documentation of EnforceDistinctSubnets).
Ticket #40009 has been opened for that.
But that the moment, the function keeps looking at /24.

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.

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.

Add an inline helper function that indicates if the cached object contains a
decrypted descriptor or not.
The descriptor object is NULL if tor is unable to decrypt it (lacking client
authorization) and some actions need to be done only when we have a decrypted
object.
This improves code semantic.
