c3e058dfac relay: Choose between IPv4 and IPv6 extends at random
When an EXTEND2 cell has an IPv4 and an IPv6 address, choose one of them
uniformly at random.

Part of 33817.

063505446f test/circuitbuild: Disable some tests when ALL_BUGS_ARE_FATAL
Some tests use IF_BUG_ONCE(), which is fatal when ALL_BUGS_ARE_FATAL,
after the fixes in 33917.

Also run "make autostyle" on these changes.

bad1181b5d relay/circuitbuild: Consider IPv6-only extends valid
Allow extend cells with IPv6-only link specifiers.
Warn and fail if both IPv4 and IPv6 are invalid.

Also warn if the IPv4 or IPv6 addresses are unexpectedly internal,
but continue with the valid address.

0bf980705e Fix a memory-leak warning in test_circuitbuid.c
Coverity wants us to free everything that we are potentially
allocating, even stuff where allocating it would be a bug.  Adding
a smartlist_free() here will fix the warning.

Fixes bug 31452; bugfix on 16a0b7ed67, which is not in
any released Tor.  This is CID 1447292.

16a0b7ed67 guard: Ignore marked for close circuit when changing state to open
When we consider all circuits in "waiting for guard" state to be promoted to
an "open" state, we were considering all circuits, even the one marked for
close.

This ultiamtely triggers a "circuit_has_opened()" called on the circuit that
is marked for close which then leads to possible undesirable behaviors within
a subsystem.

For instance, the HS subsystem would be unable to find the authentication key
of the introduction point circuit leading to a BUG() warning and a duplicate
mark for close on the circuit.

This commit also adds a unit test to make sure we never select marked for
close circuits when upgrading its guard state from waiting for guard to open.

Fixes #30871
