These now (or_port and dir_port) now have "find" names, since they
look at the portcfg first, then at the actual ports from the
listeners.

These parameters do not suppress checks, but they tell relays that
it's okay to publish even when those checks fail.
I have chosen lowercase hyphenated names, since these seem to be
more common in networkstatus params.
Closes#33224 and part of #34064.
This commit moves router_pick_published_address() and the related helper
functions into the new file.
The log_addr_has_changed() function has been made public in router.h so we can
use it in relay_resolve_addr.c.
This is a refactoring as part of Sponsor 55. Only code movement at this
commit.

Split "can extend over IPv6" and "has advertised IPv6 ORPort" into
separate functions. They currently have the same result, but this may
change in 33818 with ExtendAllowIPv6Addresses.
Part of 33817.
When IPv6 ORPorts are set to "auto", tor relays and bridges would
advertise an incorrect port in their descriptor.
This may be a low-severity memory safety issue, because the published
port number may be derived from uninitialised or out-of-bounds memory
reads.
Fixes bug 32588; bugfix on 0.2.3.9-alpha.
This patch has routers use the same canonicalization logic as
authorities when encoding their family lists. Additionally, they
now warn if any router in their list is given by nickname, since
that's error-prone.
This patch also adds some long-overdue tests for family formatting.
Since this is completely core functionality, I'm putting it in
core/mainloop, even though it depends on feature/hibernate. We'll
have to sort that out in the future.
The OpenSSL "RSA" object is currently 408 bytes compares to the ASN.1 encoding
which is 140 for a 1024 RSA key.
We save 268 bytes per descriptor (routerinfo_t) *and* microdescriptor
(microdesc_t). Scaling this to 6000 relays, and considering client usually
only have microdescriptors, we save 1.608 MB of RAM which is considerable for
mobile client.
This commit makes it that we keep the RSA onion public key (used for TAP
handshake) in ASN.1 format instead of an OpenSSL RSA object.
Changes is done in both routerinfo_t and microdesc_t.
Closes#27246

This commit won't build yet -- it just puts everything in a slightly
more logical place.
The reasoning here is that "src/core" will hold the stuff that every (or
nearly every) tor instance will need in order to do onion routing.
Other features (including some necessary ones) will live in
"src/feature". The "src/app" directory will hold the stuff needed
to have Tor be an application you can actually run.
This commit DOES NOT refactor the former contents of src/or into a
logical set of acyclic libraries, or change any code at all. That
will have to come in the future.
We will continue to move things around and split them in the future,
but I hope this lays a reasonable groundwork for doing so.
