c99 lets us do neat stuff like:

    {
      int j, k;
      foo(&j, &k);
      int z = j + k;
    }

and also
    struct point { int x; int y; };
    struct point pt = { .x=5, .y=5 };

This commit makes the configure scripts check to make sure your
compiler implements them.  It also disables our longstanding warning
about midblock declarations.

Closes ticket 13233.

Allow clients to use optimistic data when connecting to a hidden service,
which should cut out the initial round-trip for client-side programs
including Tor Browser.

(Now that Tor 0.2.2.x is obsolete, all hidden services should support
server-side optimistic data.)

See proposal 181 for details. Implements ticket 13211.

I think we should know the routerstatus for our exit relay, since
we built a circuit to it. So I think this is just a code simplication.

Clients are now willing to send optimistic circuit data (before they
receive a 'connected' cell) to relays of any version. We used to
only do it for relays running 0.2.3.1-alpha or later, but now all
relays are new enough.

Resolves ticket 13153.

Return an error when the second or later arguments of the
"setevents" controller command are invalid events. Previously we
would return success while silently skipping invalid events.

Fixes bug 13205; bugfix on 0.2.3.2-alpha. Reported by "fpxnns".

Note that this will likely need to be folded with the changes file for #12751,
as this change is a mere fixup on top of the changes introduced for #12751.

For some strange reason, this was not needed with systemd v208.
But it's needed with systemd v215 on current Debian sid, and entirely
makes sense.

Stop modifying the value of our DirReqStatistics torrc option just
because we're not a bridge or relay. This bug was causing Tor
Browser users to write "DirReqStatistics 0" in their torrc files
as if they had chosen to change the config.

Fixes bug 4244; bugfix on 0.2.3.1-alpha.
