1f958b6020 Move ext_orport identifier map into ext_orport.c

Between 042 and 043, the dirauth options were modularized so this merge commit
address this by moving the AuthDirRejectUncompressedRequests to the module
along with a series of accessors.

6d9113d2f6 dirauth: Resume sending 503 directory error code
Authorities were never sending back 503 error code because by design they
should be able to always answer directory requests regardless of bandwidth
capacity.

However, that recently backfired because of a large number of requests from
unknown source using the DirPort that are _not_ getting their 503 code which
overloaded the DirPort leading to the authority to be unable to answer to its
fellow authorities.

This is not a complete solution to the problem but it will help ease off the
load on the authority side by sending back 503 codes *unless* the connection
is from a known relay or an authority.

Fixes #33029

ee55823a11 mainloop: Rename global_write_bucket_low()
That function is only used to test the global bucket write limit for a
directory connection.

It should _not_ be used for anything else since that function looks to see if
we are a directory authority.

Rename it to something more meaningful. No change in behavior at this commit,
only renaming.

mainloop: Simplify ip_address_changed()
Simplify ip_address_changed() by removing redundant checks
(all exits are relays, and need to rebuild their descriptor when their
IP addresses change).

Rewrite the function comment, and rename the argument, so the function
is easier to understand and use.

config: Make clients tell dual-stack exits they prefer IPv6
Make Tor clients tell dual-stack exits that they prefer IPv6
connections.

This change is equivalent to setting the PreferIPv6 flag on
SOCKSPorts (and most other listener ports). Tor Browser has
been setting this flag for some time, and we want to remove a
client distinguisher at exits.

Also update the man page, putting all the IP flags in their
non-default forms.

Closes ticket 32637.
