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.
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.
When we close a socket via tor_tls_free(), we previously had no way
for our socket accounting logic to learn about it. This meant that
the socket accounting code would think we had run out of sockets,
and freak out.
Fixes bug 27795; bugfix on 0.3.5.1-alpha.
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.
There are now separate modules for:
* the list of router descriptors
* the list of authorities and fallbacks
* managing authority certificates
* selecting random nodes
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.
This patch moves the logic that adds the proxy headers to an earlier
point in the exit connection lifetime, which ensures that the
application data cannot be written to the outbuf before the proxy header
is added.

This patch changes HiddenServiceExportCircuitID so instead of being a
boolean it takes a string, which is the protocol. Currently only the
'haproxy' protocol is defined.

Without this patch we would encode the IPv6 address' last part as
::ffffffff instead of ::ffff:ffff when the GID is UINT32_MAX.

We determine that a cell was dropped by inspecting CIRC_BW fields. If we did
not update the delivered or overhead fields after processing the cell, the
cell was dropped/not processed.
Also emit CIRC_BW events for cases where we decide to close the circuit in
this function, so vanguards can print messages about dropped cells in those
cases, too.
