This is also used by onion services, so it needs to go in another
module.

194acfb51d Split directory.c code into several modules
Parts of this C file naturally belong in dircache, dirclient, and
dircommon: so, move them there.

c7ce6b9821 Split main.c into main.c and mainloop.c
The main.c code is responsible for initialization and shutdown;
the mainloop.c code is responsible for running the main loop of Tor.

Splitting the "generic event loop" part of mainloop.c from the
event-loop-specific part is not done as part of this patch.

98ef3e82e4 Move the non-crypto parts of onion.c out of src/core/crypto
The parts for handling cell formats should be in src/core/or.

The parts for handling onionskin queues should be in src/core/or.

Only the crypto wrapper belongs in src/core/crypto.

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.

08e3b88f07 Split routerlist.c into 4 separate modules
There are now separate modules for:
    * the list of router descriptors
    * the list of authorities and fallbacks
    * managing authority certificates
    * selecting random nodes

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.

12a1ada158 Move the initialization and cleanup parts of crypto.c
These are now part of crypto_init.c.  The openssl-only parts now
live in crypto_openssl_mgt.c.

63b4ea22af Move literally everything out of src/or
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.
