ce854a8d22 Add -ftrapv to gcc-hardening ... mostly!
We know there are overflows in curve25519-donna-c32, so we'll have
to have that one be fwrapv.

Only apply the asan, ubsan, and trapv options to the code that does
not need to run in constant time.  Those options introduce branches
to the code they instrument.

(These introduced branches should never actually be taken, so it
might _still_ be constant time after all, but branch predictors are
complicated enough that I'm not really confident here. Let's aim for
safety.)

Closes 17983.

80a6c8caa3 Basic work on a publish/subscribe abstraction
The goal here is to provide a way to decouple pieces of the code
that want to learn "when something happens" from those that realize
that it has happened.

The implementation here consists of a generic backend, plus a set of
macros to define and implement a set of type-safe frontends.

bf3e32a452 Fix out-of-bounds write during voting with duplicate ed25519 keys
In dirserv_compute_performance_thresholds, we allocate arrays based
on the length of 'routers', a list of routerinfo_t, but loop over
the nodelist. The 'routers' list may be shorter when relays were
filtered by routers_make_ed_keys_unique, leading to an out-of-bounds
write on directory authorities.

This bug was originally introduced in 26e89742, but it doesn't look
possible to trigger until routers_make_ed_keys_unique was introduced
in 13a31e72.

Fixes bug 19032; bugfix on tor 0.2.8.2-alpha.

50d777dcf4 Split directory_handle_command_get into subfunctions.
This was one of our longest functions, at 600 lines.  It makes a nice
table-driven URL-based function instead.

The code is a bit ugly, it leave the indentation as it is in hopes of
making pending directory.c changes easier to merge.  Later we can
clean up the indentation.

Also, remove unused mallinfo export code from directory.c

be0e1e9e2f Stop being so strict about the payload length of "rendezvous1" cells
We used to be locked in to the "tap" handshake length, and now we can
handle better handshakes like "ntor".

Resolves ticket 18998.

I checked that relay_send_command_from_edge() behaves fine when you
hand it a payload with length 0. Clients behave fine too, since current
clients remain strict about the required length in the rendezvous2 cells.
(Clients will want to become less strict once they have an alternate
format that they're willing to receive.)

d5a23ce115 Move rend auth cookie en-/decoding to a function
Tor stores client authorization cookies in two slightly different forms.
The service's client_keys file has the standard base64-encoded cookie,
including two chars of padding. The hostname file and the client remove
the two padding chars, and store an auth type flag in the unused bits.

The distinction makes no sense. Refactor all decoding to use the same
function, which will accept either form, and use a helper function for
encoding the truncated format.
