43ffd023e9 Make SIZE_T_CEILING unsigned; add a signed SSIZE_T_CEILING
None of the comparisons were _broken_ previously, but avoiding
signed/unsigned comparisons makes everybody happier.

Fixes bug2475.

785086cfba Have all of our allocation functions and a few others check for underflow
It's all too easy in C to convert an unsigned value to a signed one,
which will (on all modern computers) give you a huge signed value.  If
you have a size_t value of size greater than SSIZE_T_MAX, that is way
likelier to be an underflow than it is to be an actual request for
more than 2gb of memory in one go.  (There's nothing in Tor that
should be trying to allocate >2gb chunks.)

213139f887 Properly refcount client_identity_key
In a2bb0bf we started using a separate client identity key. When we are
in "public server mode" (that means not a bridge) we will use the same
key. Reusing the key without doing the proper refcounting leads to a
segfault on cleanup during shutdown. Fix that.

Also introduce an assert that triggers if our refcount falls below 0.
That should never happen.

14bc4dcc22 Rename log.h to torlog.h
This should make us conflict less with system files named "log.h".
Yes, we shouldn't have been conflicting with those anyway, but some
people's compilers act very oddly.

The actual change was done with one "git mv", by editing
Makefile.am, and running
   find . -name '*.[ch]' | xargs perl -i -pe 'if (/^#include.*\Wlog.h/) {s/log.h/torlog.h/; }'

3807db001d *_free functions now accept NULL
Some *_free functions threw asserts when passed NULL. Now all of them
accept NULL as input and perform no action when called that way.

This gains us consistence for our free functions, and allows some
code simplifications where an explicit null check is no longer necessary.

5e4d53d535 Remove checks for array existence. (CID 410..415)
In C, the code "char x[10]; if (x) {...}" always takes the true branch of
the if statement.  Coverity notices this now.

In some cases, we were testing arrays to make sure that an operation
we wanted to do would suceed.  Those cases are now always-true.

In some cases, we were testing arrays to see if something was _set_.
Those caes are now tests for strlen(s), or tests for
!tor_mem_is_zero(d,len).

d2b4b49ff0 Reduce log level for someone else sending us weak DH keys.
See task 1114. The most plausible explanation for someone sending us weak
DH keys is that they experiment with their Tor code or implement a new Tor
client. Usually, we don't care about such events, especially not on warn
level. If we really care about someone not following the Tor protocol, we
can set ProtocolWarnings to 1.

This patch introduces a new type called document_signature_t to represent the

to one document signature per voter per digest algorithm.  Also, each
detached-signatures document can have up to one signature per <voter,
algorithm, flavor>.

This shouldn't be necessary, but apparently the Android cross-compiler
doesn't respect -I as well as it should.  (-I is supposed to add to the
*front* of the search path.  Android's gcc wrapper apparently likes to add to
the end.  This is broken, but we need to work around it.)

d0c212995a Add a SHA256 implementation for platforms that lack it.
(This would be everywhere running OpenSSL 0.9.7x and earlier, including
all current Macintosh users.)

The code is based on Tom St Denis's LibTomCrypt implementation,
modified to be way less general and use Tor's existing facilities.  I
picked this one because it was pretty fast and pretty free, and
because Python uses it too.

oprofile was telling me that a fair bit of our time in openssl was spent in base64_decode, so replace base64_decode with an all-at-once fairly optimized implementation.  For decoding keys and digests, it seems 3-3.5x faster than calling out to openssl.  (Yes, I wrote it from scratch.)
