b5d6e47002 Warning message when bug 10722 would trigger 
If somebody's excludenodes settings are keeping their hidden service
connections from working, they should probably get notified about it.

3f567f529f gcc/clang: Mark macro-generated functions as possible unused 
clang 3.4 introduced a new by-default warning about unused static
functions, which we triggered heavily for the hashtable and map function
generating macros. We can use __attribute__ ((unused)) (thanks nickm for
the suggestion :-) ) to silence these warnings.

ac5ae794bd tristate->enum in rendcommon functions 
When we have more than two return values, we should really be using
an enum rather than "-2 means this, -1 means that, 0 means this, and
1 or more means a number."

436f7106b4 Exclude Teredo IPv6 prefix from geoip6. 
The latest GeoLite2 database includes a pointer from 2001::/32 to the root
node of the IPv4 address space in the tree.  We need to exclude this whole
address space from geoip6, similar to how we exclude IPv4-mapped IPv6
addresses and the 6to4 mapping subnet.

24add404ac eventdns.c: survive broken resolv.conf files 
If you had a resolv.conf file with a nameserver line containing no
nameserver IP, we would crash.  That's not terrible, but it's not
desirable.

Fixes bug 8788; bugfix on 0.1.1.23.  Libevent already has this fix.

9a07ec751f Refactor OOM-handling functions for more testability 
This patch splits out some of the functions in OOM handling so that
it's easier to check them without involving the rest of Tor or
requiring that the circuits be "wired up".

c1e98c8afe Randomize the global siphash key at startup

d3fb846d8c Split crypto_global_init() into pre/post config 
It's increasingly apparent that we want to make sure we initialize our
PRNG nice and early, or else OpenSSL will do it for us.  (OpenSSL
doesn't do _too_ bad a job, but it's nice to do it ourselves.)

We'll also need this for making sure we initialize the siphash key
before we do any hashes.

0e97c8e23e Siphash-2-4 is now our hash in nearly all cases. 
I've made an exception for cases where I'm sure that users can't
influence the inputs.  This is likely to cause a slowdown somewhere,
but it's safer to siphash everything and *then* look for cases to
optimize.

This patch doesn't actually get us any _benefit_ from siphash yet,
since we don't really randomize the key at any point.

f4656c0cc9 Raw import of Marek Majkowski's cisphash.c 
siphash is a hash function designed for producing hard-to-predict
64-bit outputs from short inputs and a 128-bit key.  It's chosen for
security and speed.

See https://131002.net/siphash/ for more information on siphash.
