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.
"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".

with quotes from "robgjansen".
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).
* 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.)
Instead of having it call update_all_descriptor_downloads and
update_networkstatus_downloads directly, we can have it cause them to
get rescheduled and called from run_scheduled_events.
Closes ticket 16789.
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.

When we removed Running/Valid checks from Fast and Stable in 8712, I
removed them from HSDir too, which apparently wasn't a good idea.
Reverts part of a65e835800. Fixes bug 16524. Bugfix
on 0.2.7.2-alpha.
microdesc_free_() called get_microdesc_cache(), which had the fun
side-effect of potentially reloading the whole cache from disk.
Replace it with a variant that doesn't.
The base64 and base32 functions used to be in crypto.c;
crypto_format.h had no header; some general-purpose functions were in
crypto_curve25519.c.
This patch makes a {crypto,util}_format.[ch], and puts more functions
there. Small modules are beautiful!
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.

1) We already require C99.
2) This allows us to support MSVC again (thanks to Gisle Vanem for
this part)
3) This change allows us to dump some rotten old compatibility code
from log.c
Make sure that signing certs are signed by the right identity key,
to prevent a recurrence of #16530. Also make sure that the master
identity key we find on disk matches the one we have in RAM, if we
have one.
This is for #16581.
