d0d9c3d71e Fix parse_http_time and add tests
* It seems parse_http_time wasn't parsing correctly any date with commas (RFCs
  1123 and 850). Fix that.
* It seems parse_http_time was reporting the wrong month (they start at 0, not
  1). Fix that.
* Add some tests for parse_http_time, covering all three formats.

9b344628ed Handle out-of-range values in tor_parse_* integer functions
The underlying strtoX functions handle overflow by saturating and
setting errno to ERANGE.  If the min/max arguments to the
tor_parse_* functions are equal to the minimum/maximum of the
underlying type, then with the old approach, we wouldn't treat a
too-large value as genuinely broken.

Found this while looking at bug 5786; bugfix on 19da1f36 (in Tor
0.0.9), which introduced these functions.

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.

5d147d8527 Add a new flag to check_private_dir to make it _not_ change permissions
We'll need this for checking permissions on the directories that hold
control sockets: if somebody says "ControlSocket ~/foo", it would be
pretty rude to do a chmod 700 on their homedir.

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.

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/; }'

03ea5f930e Reinstate warning when HOME isn't set.
Having ~/.tor expand into /.tor is, after all, almost certainly not
what the user wanted, and it deserves a warning message.

Also, convert a guess-and-malloc-and-sprintf triple into an asprintf.

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.

d35b8dc582 Make expand_filename into a tor_strdup() alias on windows.
On Windows, we don't have a notion of ~ meaning "our homedir", so we
were deliberately using an #ifdef to avoid calling expand_filename()
in multiple places.  This is silly: The right place to turn a function
into a no-op on a single platform is in the function itself, not in
every single call-site.
