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.

3acb27af3d Add unit tests for dirserv_set_routerstatus_testing
Test that TestingDirAuthVote{Exit,Guard,HSDir}[Strict] work on
routersets matching all routers, one router, and no routers.

TestingDirAuthVote{Exit,Guard,HSDir} set the corresponding flag
on routerstatuses which match the routerset, but leave other flags
unmodified.

TestingDirAuthVote{Exit,Guard,HSDir}Strict clear the corresponding flag
on routerstatuses which don't match the routerset.

d1c94dcbea Refactor TestingDirAuthVote* into dirserv_set_routerstatus_testing
Make it easier to unit test TestingDirAuthVote{Exit,Guard,HSDir}
by refactoring the code which sets flags based on them into a
new function dirserv_set_routerstatus_testing.

359faf5e4b New TestingDirAuthVote{Exit,Guard,HSDir}IsStrict flags
"option to prevent guard,exit,hsdir flag assignment"

"A node will never receive the corresponding flag unless
that node is specified in the
TestingDirAuthVote{Exit,Guard,HSDir} list, regardless of
its uptime, bandwidth, exit policy, or DirPort".

Patch modified by "teor": VoteOnHidServDirectoriesV2
is now obsolete, so TestingDirAuthVoteHSDir always
votes on HSDirs.

Closes ticket 14882. Patch by "robgjansen".

0cb82013cc Fix TestingDirAuthVoteHSDir docs: HSDir flag needs DirPort
Fix an error in the manual page and comments for
TestingDirAuthVoteHSDir, which suggested that a
HSDir required "ORPort connectivity". While this is true,
it is in no way unique to the HSDir flag. Of all the flags,
only HSDirs need a DirPort configured in order for the
authorities to assign that particular flag.

Fixed as part of 14882. Patch by "teor".
Bugfix on 0.2.6.3 (f9d57473e1 on 10 January 2015).

971eba0fcd Fixup: Force enable SSE2 before undefining ALIGN if SSE2 is disabled.
This should fix the x86 build, since variables that require 16 byte
alignment will now actually be 16 byte aligned.

a77616f605 Enable ed25519-donna's SSE2 code when possible for 32 bit x86.
This probably requires the user to manually set CFLAGS, but should
result in a net gain on 32 bit x86. Enabling SSE2 support would be
possible on x86_64, but will result in slower performance.

Implements feature #16535.

2e0a50abf4 Remove redundant tor_free() in command_process_create_cell().
* FIXES #16823: https://bugs.torproject.org/16823
   If an OP were to send a CREATE_FAST cell to an OR, and that
   CREATE_FAST cell had unparseable key material, then tor_free() would
   be called on the create cell twice.  This fix removes the second
   (conditional on the key material being bad) call to tor_free(), so
   that now the create cell is always freed once, regardless of the status of
   the key material.

   (This isn't actually a double-free bug, since tor_free() sets its
   input to NULL, and has no effect when called with input NULL.)

ab9a0e3407 Add rend failure cache
When fetching a descriptor, we know test every introduction points in it
against our rend failure cache to know if we keep it or not. For this to
work, now everytime an introduction points is discareded (ex: receiving a
NACK), we note it down in our introduction cache.

See rendcache.c for a detailed explanation of the cache's behavior.
