5d1d7afcd3 Use the correct SIGNED_KEY_TYPE value for signing->link certs
Our code was using [01] as for the key type of signed->link certs,
which was incorrect.  The value should be [03], to indicate that the
value as the SHA256 of an x.509 cert.

Fortunately, nothing cares about this value, so there shouldn't be
compatibility issues.

Fixes bug 40124; bugfix on 0.2.7.2-alpha.

c92e19268b Rename tor_cert_create to tor_cert_create_ed25519
This is an automated commit, generated by this command:

./scripts/maint/rename_c_identifier.py \
        tor_cert_create tor_cert_create_ed25519

It was generated with --no-verify, so it probably breaks some commit hooks.
The commiter should be sure to fix them up in a subsequent commit.

83052372a0 relay: Query our cache when deciding for dummy descriptor fetch
Instead of looking at the "Address" option alone, instead check if we have an
address in our cache (that is discovered by tor). If not, then it tells us
that tor does not have an address to work with so we can then ask a directory
authority for a suggestion.

b417594dbc Replace several C identifiers for ticket 18106.
We used to have a single boolean, "FascistFirewall".  Ages ago, in
tickets #17840 and #9067, we added an improved "ReachableAddresses"
mechanism.  It's time to rename related identifiers in the code for
consistency.  This closes #18106.

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.

192d367b41 addr: New function relay_address_new_suggestion()
This behaves like router_new_address_suggestion() but differs in couple of
ways:

  1. It takes a tor_addr_t instead of an address string and supports both
     AF_INET and AF_INET6.
  2. It does _not_ use the last_guessed_ip local cache and instead only relies
     on the last resolved address cache in resolve_addr.c

It is not used at this commit. This function is made to process a suggested
address found in a NETINFO cell exactly like router_new_address_suggestion()
does with the address a directory suggests us.

e93ad428e2 Allow multiple addresses in extend_info_t.
In practice, there will be at most one ipv4 address and ipv6 address
for now, but this code is designed to not care which address is
which until forced to do so.

This patch does not yet actually create extend_info_t objects with
multiple addresses.

Closes #34069.

1f58b0ca26 router: Authorities add their own IPv6 to trusted dir servers
Authorities currently add themselves to the trusted dir servers list,
but if they have an IPv6 ORPort, they leave it out.

This commit makes authorities add their own IPv6 ORPort to the trusted
dir servers list.

6edf7f6710 Add two new networkstatus parameters to emulate AssumeReachable.
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.
