addd181721 Fix memory leak in TestingEnableCellStatsEvent
Only when we were actually flushing the cell stats to a controller
would we free them.  Thus, they could stay in RAM even after the
circuit was freed (eg if we didn't have any controllers).

Fixes bug 18673; bugfix on 0.2.5.1-alpha.

Modify callers to correctly handle these new NULL returns:
* fix assert in onion_extend_cpath
* warn and discard circuit in circuit_get_open_circ_or_launch

10a6390deb Add controller getinfo exit-policy/reject-private
exit-policy/reject-private lists the reject rules added by
ExitPolicyRejectPrivate. This makes it easier for stem to
display exit policies.

Add unit tests for getinfo exit-policy/*.

d47a4aec66 Separate lookup function for service rend cache
Performing lookups in both the client and service side descriptor
caches from the same rend_cache_lookup_entry() function increases the
risk of accidental API misuse.

I'm separating the lookup functions to keep the caches distinct.

293410d138 Add replica number to HS_DESC CREATED event
Including the replica number in the HS_DESC CREATED event provides
more context to a control port client. The replica allows clients
to more easily identify each replicated descriptor from the
independantly output control events.

1a75e6da00 Create a service-side descriptor cache
Adds a service descriptor cache which is indexed by service ID. This
descriptor cache is used to store service descriptors generated by a
local rendevous service.

The service-side cach can be queried by calling rend_cache_lookup_entry()
with the 'service' argument set to 1.

60c8fbf1ff Remove obsolete event_format_t
We used to use this when we had some controllers that would accept

while, and it's time to strip it out of the code.

bab221f113 Refactor our logic for sending events to controllers
Previously we'd put these strings right on the controllers'
outbufs. But this could cause some trouble, for these reasons:

  1) Calling the network stack directly here would make a huge portion
     of our networking code (from which so much of the rest of Tor is
     reachable) reachable from everything that potentially generated
     controller events.

  2) Since _some_ events (EVENT_ERR for instance) would cause us to
     call connection_flush(), every control_event_* function would
     appear to be able to reach even _more_ of the network stack in
     our cllgraph.

  3) Every time we generated an event, we'd have to walk the whole
     connection list, which isn't exactly fast.

This is an attempt to break down the "blob" described in
http://archives.seul.org/tor/dev/Mar-2015/msg00197.html -- the set of
functions from which nearly all the other functions in Tor are
reachable.

Closes ticket 16695.

8c83e8cec0 Add get_max_sockets() and remove dead code
The control port was using set_max_file_descriptors() with a limit set to 0
to query the number of maximum socket Tor can use. With the recent changes
to that function, a check was introduced to make sure a user can not set a
value below the amount we reserved for non socket.

This commit adds get_max_sockets() that returns the value of max_sockets so
we can stop using that "setter" function to get the current value.

Finally, the dead code is removed that is the code that checked for limit
equal to 0. From now on, set_max_file_descriptors() should never be used
with a limit set to 0 for a valid use case.

Fixes #16697
