9f25a5529a Fix an assertion-failure in memarea_alloc() on 64-bit platforms. 
The trick is that we should assert that our next_mem pointer has not
run off the end of the array _before_ we realign the pointer, since
doing that could take us over the end... but only if we're on a system
where malloc() gives us ram in increments smaller than sizeof(void*).

c36efb0c45 Use a mutex to protect the count of open sockets. 
This matters because a cpuworker can close its socket when it
finishes.  Cpuworker typically runs in another thread, so without a
lock here, we can have a race condition and get confused about how
many sockets are open.  Possible fix for bug 939.

d9650cfa50 Add sentinel values to the end of memarea chunks. 
This might detect some possible causes of bug 930, and will at least
make sure we aren't doing some dumb memory-corruption stuff with the heap
and router-parsing.

any unrelated source file in src/common or src/or has changed.

6ac3a8b0cd Command-line option to dump SHA1 digests of all source files. 
Now, when you call tor --digests, it dumps the SHA1 digest of each
source file that Tor was built with.  We support both 'sha1sum' and
'openssl sha1'.  If the user is building from a tarball and they
haven't edited anything, they don't need any program that calculates
SHA1.  If they _have_ modified a file but they don't have a program to
calculate SHA1, we try to build so we do not output digests.

26d83fc04c Add a simple locale-independent no-surprises sscanf replacement. 
tor_sscanf() only handles %u and %s for now, which will make it
adequate to replace sscanf() for date/time/IP parsing.  We want this
to prevent attackers from constructing weirdly formed descriptors,
cells, addresses, HTTP responses, etc, that validate under some
locales but not others.

9f8d095e0f Add and use set/get_uint64 on onion tags. [bug 604; backportable] 
It seems that 64-bit Sparc Solaris demands 64-bit-aligned access to
uint64_t, but does not 64-bit-align the stack-allocated char array we
use for cpuworker tags.  So this patch adds a set/get_uint64 pair, and
uses them to access the conn_id field in the tag.

8ebceeb352 Make sure that even in the weird fiddly paths that lead to init_keys, 
crypto_global_init gets called.  Also have it be crypto_global_init
that calls crypto_seed_rng, so we are not dependent on OpenSSL's
RAND_poll in these fiddly cases.
