426c9561c5 Use nodefamily_t in microdescriptors. 
Closes ticket 27359.

83be4d2bbd Backend for compact node-family representation. 
This representation is meant to save memory in microdescriptors --
we can't use it in routerinfo_t yet, since those families need to be
encoded losslessly for directory voting to work.

This representation saves memory in three ways:
   1. It uses only one allocation per family.  (The old way used a
      smartlist (2 allocs) plus one strdup per entry.)
   2. It stores identity digests in binary, not hex.
   3. It keeps families in a canonical format, memoizes, and
      reference-counts them.

Part of #27359.

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.

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.

e3713f17fb node: Make node_supports_v3_rendezvous_point() also check for the key 
It is not enough to look at protover for v3 rendezvous support but also we
need to make sure that the curve25519 onion key is present or in other words
that the descriptor has been fetched and does contain it.

Fixes #27797.

7ace8d5a61 Assert that some trunnel _new() functions return non-NULL 
The trunnel functions are written under the assumption that their
allocators can fail, so GCC LTO thinks they might return NULL.  In
point of fact, they're using tor_malloc() and friends, which can't
fail, but GCC won't necessarily figure that out.

Fixes part of #27772.
