dff73d26f3 Merge remote-tracking branch 'public/bug5089'
Conflicts:
	src/test/test_util.c

Merge the unit tests; I added some when I did this branch against
0.2.2, and then the test format changed and master added more tests.

0e207f9acb Merge remote-tracking branch 'public/close_file_mapping'
Conflicts:
	src/common/compat.h

Conflict was between replacement of MS_WINDOWS with _WIN32 in
master, and with removal of file_handle from tor_mmap_t struct in
close_file_mapping branch (for bug 5951 fix).

254504fc14 Have get_parent_directory() handle "/foo" and "/" correctly.
The parent of "/foo" is "/"; and "/" is its own parent.

This would cause Tor to fail if you tried to have a PF_UNIX control
socket in the root directory.  That would be a stupid thing to do
for other reasons, but there's no reason to fail like _this_.

Bug found by Esteban Manchado Velázquez. Fix for bug 5089; bugfix on
Tor 0.2.2.26-beta.  Unit test included.

a2f0e7a65b Cut down on the OS information we give.
For uname-based detection, we now give only the OS name (e.g.,
"Darwin", "Linux".)  For Windows, we give only the Operating System
name as inferred from dw(Major|Minor)version, (e.g., "Windows XP",
"Windows 7"), and whether the VER_NT_SERVER flag is set.

For ticket 2988.

a1538d607d Fix bug 5762: detect missing accept4 that gives ENOSYS
We had been checking for EINVAL, but that means that SOCK_* isn't
supported, not that the syscall itself is missing.

Bugfix on 0.2.3.1-alpha, which started to use accept4.

c03a233faa Remove __ from HAVE_EXTERN_ENVIRON_DECLARED__
I think that the trailing __ got added in false analogy to
HAVE_MACRO__func__, HAVE_MACRO__FUNC__, and HAVE_MACRO__FUNCTION__.
But those macros actually indicate the presence of __func__,
__FUNC__, and __FUNCTION__ respectively.  The __ at the end of
HAVE_EXTERN_ENVIRON_DECLARED would only be appropriate if the
environ were declared__, whatever that means.

(As a side-note, HAVE_MACRO__func__ and so on should probably be
renamed HAVE_MACRO___func__ and so on.  But that can wait.)

This is an identifier renaming only.

efb8a09f41 Fix tor_strtok_r_impl and test cases per bug #5091
==

Nick here. I tweaked this patch a little to make it apply cleanly to
master, to extract some common code into a function, and to replace
snprintf with tor_snprintf.

077b9f19a4 If SOCK_CLOEXEC and friends fail, fall back to regular socket() calls
Since 0.2.3.1-alpha, we've supported the Linux extensions to socket(),
open(), socketpair(), and accept() that enable us to create an fd and
make it close-on-exec with a single syscall.  This not only saves us a
syscall (big deal), but makes us less vulnerable to race conditions
where we open a socket and then exec before we can make it
close-on-exec.

But these extensions are not supported on all Linuxes: They were added
between 2.6.23 or so and 2.6.28 or so.  If you were to build your Tor
against a recent Linux's kernel headers, and then run it with a older
kernel, you would find yourselve unable to open sockets.  Ouch!

The solution here is that, when one of these syscalls fails with
EINVAL, we should try again in the portable way.  This adds an extra
syscall in the case where we built with new headers and are running
with old ones, but it will at least allow Tor to work.

Fixes bug 5112; bugfix on 0.2.3.1-alpha.

9c29369a04 Convert instances of tor_malloc+tor_snprintf into tor_asprintf
These were found by looking for tor_snprintf() instances that were
preceeded closely by tor_malloc(), though I probably converted some
more snprintfs as well.

(In every case, make sure that the length variable (if any) is
removed, renamed, or lowered, so that anything else that might have
assumed a longer buffer doesn't exist.)

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.
