db4cde3810 Improve the code a tad.
* Use strcmpstart() instead of strcmp(x,y,strlen(y)).
* Warn the user if the managed proxy failed to launch.
* Improve function documentation.
* Use smartlist_len() instead of n_unconfigured_proxies.
* Split managed_proxy_destroy() to managed_proxy_destroy()
  and managed_proxy_destroy_with_transports().
* Constification.

e802199cb3 Initial patch to build Tor with msvc and nmake
We'll still need to tweak it so that it looks for includes and
libraries somewhere more sensible than "where we happened to find
them on Erinn's system"; so that tests and tools get built too;
so that it's a bit documented; and so that we actually try running
the output.

Work done with Erinn Clark.

773bfaf91e Implement stream isolation
This is the meat of proposal 171: we change circuit_is_acceptable()
to require that the connection is compatible with every connection
that has been linked to the circuit; we update circuit_is_better to
prefer attaching streams to circuits in the way that decreases the
circuits' usefulness the least; and we update link_apconn_to_circ()
to do the appropriate bookkeeping.

54d7d31cba Make ControlSocketsGroupWritable work with User.
Original message from bug3393:

check_private_dir() to ensure that ControlSocketsGroupWritable is
safe to use. Unfortunately, check_private_dir() only checks against
the currently running user… which can be root until privileges are
dropped to the user and group configured by the User config option.

The attached patch fixes the issue by adding a new effective_user
argument to check_private_dir() and updating the callers. It might
not be the best way to fix the issue, but it did in my tests.

cfeafe5e77 Use a 64-bit type to hold sockets on win64.
On win64, sockets are of type UINT_PTR; on win32 they're u_int;
elsewhere they're int.  The correct windows way to check a socket for
being set is to compare it with INVALID_SOCKET; elsewhere you see if
it is negative.

On Libevent 2, all callbacks take sockets as evutil_socket_t; we've
been passing them int.

This patch should fix compilation and correctness when built for
64-bit windows.  Fixes bug 3270.

59f9097d5c Hand-conversion and audit phase of memcmp transition
Here I looked at the results of the automated conversion and cleaned
them up as follows:

   If there was a tor_memcmp or tor_memeq that was in fact "safe"[*] I
   changed it to a fast_memcmp or fast_memeq.

   Otherwise if there was a tor_memcmp that could turn into a
   tor_memneq or tor_memeq, I converted it.

This wants close attention.

[*] I'm erring on the side of caution here, and leaving some things
as tor_memcmp that could in my opinion use the data-dependent
fast_memcmp variant.

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.)

c0c7868250 Make the windows build succeed with or without -DUNICODE enabled.
This should keep WinCE working (unicode always-on) and get Win98
working again (unicode never-on).

There are two places where we explicitly use ASCII-only APIs, still:
in ntmain.c and in the unit tests.

This patch also fixes a bug in windoes tor_listdir that would cause
the first file to be listed an arbitrary number of times that was
also introduced with WinCE support.

Should fix bug 1797.

Yes, we shouldn't have been conflicting with those anyway, but some

   find . -name '*.[ch]' | xargs perl -i -pe 'if (/^#include.*\Wlog.h/) {s/log.h/torlog.h/; }'

8d31141ccb Port Tor to work on Windows CE
Most of the changes here are switches to use APIs available on Windows
CE.  The most pervasive change is that Windows CE only provides the
wide-character ("FooW") variants of most of the windows function, and
doesn't support the older ASCII verions at all.

This patch will require use of the wcecompat library to get working
versions of the posix-style fd-based file IO functions.
