Fall back to registered country if necessary.
When extracting geoip and geoip6 files from MaxMind's GeoLite2 Country
database, we only look at country->iso_code which is the two-character ISO
3166-1 country code of the country where MaxMind believes the end user is
located.
But if MaxMind thinks a range belongs to anonymous proxies, they don't put
anything there. Hence, we omit those ranges and resolve them all to '??'.
That's not what we want.
What we should do is first try country->iso_code, and if there's no such
key, try registered_country->iso_code which is the country in which the
ISP has registered the IP address.
In short: let's fill all A1 entries with what ARIN et. al think.

If the cert turns out to be invalid or if wget is otherwise unable to
verify it, it's going to return an error and not download the file for us.

It's possible for two threads to hit assertion failures at the same
time. If that happens, let's keep them from stomping on the same
cb_buf field.
Fixes bug 11048; bugfix on 0.2.5.2-alpha. Reported by "cypherpunks".
This should make more platforms (in particular, ones with compilers
where -fomit-frame-pointer is on by default but table generation
isn't) support backtrace generation. Thanks to cypherpunks for this
one.
Fixes bug 11047; bugfix on 0.2.5.2-alpha.
Back in 5e762e6a5c, non-exit servers
stopped launching DNS requests for users. So there's no need for them
to see if their DNS answers are hijacked.
Patch from Matt Pagan. I think this is a 965 fix.
For a client using a SocksPort connection and IPv6, the connect reply
from tor daemon did not handle AF_INET6 thus sending back the wrong
payload to the client.
A changes file is provided and this fixes#10987

Since the first stat call is made for it to deliberately fail, and we
reference st.st_mode without st having valid data, st.st_mode can contain
garbage and cause chmod to fail with EINVAL. We rerun stat and ensure it
succeeded.
Also make use of tt_abort_perror, to properly convey failure reasons to
the user.
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.
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."
On busy servers, this function takes up something like 3-7% in
different profiles, and gets invoked every time we need to participate
as the midpoint in a hidden service.
So maybe walking through a linked list of all the circuits here wasn't
a good idea.
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.
