cc397449fc Use __attribute__((fallthrough)) rather than magic GCC comments.
GCC added an implicit-fallthrough warning a while back, where it
would complain if you had a nontrivial "case:" block that didn't end
with break, return, or something like that.  Clang recently added
the same thing.

GCC, however, would let you annotate a fall-through as intended by
any of various magic "/* fall through */" comments.  Clang, however,
only seems to like "__attribute__((fallthrough))".  Fortunately, GCC
accepts that too.

A previous commit in this branch defined a FALLTHROUGH macro to do
the right thing if GNUC is defined; here we replace all of our "fall
through" comments with uses of that macro.

This is an automated commit, made with the following perl one-liner:

  #!/usr/bin/perl -i -p
  s#/\* *falls? ?thr.*?\*/#FALLTHROUGH;#i;

Lowercase the BridgeDistribution value from torrc in descriptors.
This patch ensures that we always lowercase the BridgeDistribution from
torrc in descriptors before submitting it.

2da4d64a64 Avoid a crash if our "current" and "old" ntor onion keys are equal
Our dimap code asserts if you try to add the same key twice; this
can't happen if everything is running smoothly, but it's possible if
you try to start a relay where secret_onion_key_ntor is the same as
secret_onion_key_ntor.old.

Fixes bug 30916; bugfix on 0.2.4.8-alpha when ntor keys were
introduced.

37aae23945 OOM-purge the DNS cache one part at a time
Previously we purged it in 1-hour increments -- but one-hour is the
maximum TTL for the cache!  Now we do it in 25%-TTL increments.

Fixes bug 29617; bugfix on 0.3.5.1-alpha.

b54a5e704f Split most of dirserv.c into several new modules
In dirauth:
  * bwauth.c reads and uses bandwidth files
  * guardfraction.c reads and uses the guardfraction file
  * reachability.c tests relay reachability
  * recommend_pkg.c handles the recommended-packages lines.
  * recv_descs.c handles fingerprint files and processing incoming
    routerinfos that relays upload to us
  * voteflag.c computes flag thresholds and sets those thresholds on
    routerstatuses when computing votes

In control:
  * fmt_serverstatus.c generates the ancient "v1 server status"
    format that controllers expect.

In nodelist:
  * routerstatus_fmt.c formats routerstatus entries for a consensus,
    a vote, or for the controller.

600e046ed3 Rename crypto_pk_check_key(), use it more reasonably, add tests
This function was a wrapper around RSA_check_key() in openssl, which
checks for invalid RSA private keys (like those where p or q are
composite, or where d is not the inverse of e, or where n != p*q).
We don't need a function like this in NSS, since unlike OpenSSL, NSS
won't let you import a bogus private key.

I've renamed the function and changed its return type to make it
more reasonable, and added a unit test for trying to read a key
where n != p*q.

2f6bc74914 router: Keep RSA onion public key in ASN.1 format
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

cb466ee7d6 key: Make ed_key_init_from_file() take an or_options_t
Part of #27215, we need to call the ed_key_init_from_file function during
option_validate() which is before the global_options variable is set.

This commit make ed_key_init_from_file() stop using get_options() and instead
now has a or_options_t parameter.
