b8a7bad799 Make payloads into uint8_t.
This will avoid some signed/unsigned assignment-related bugs.

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.)

fd992deeea Don't attempt to log messages to a controller from a worker thread.
This patch adds a function to determine whether we're in the main
thread, and changes control_event_logmsg() to return immediately if
we're in a subthread.  This is necessary because otherwise we will
call connection_write_to_buf, which modifies non-locked data
structures.

Bugfix on 0.2.0.x; fix for at least one of the things currently
called "bug 977".

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.

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.

c4b8fef362 Remove svn $Id$s from our source, and remove tor --version --version.

whatever file got committed.  They were not actually useful for
telling the version of Tor files in the wild.
