Make default signal backend fully threadsafe
Jason Toffaletti discovered with helgrind that our signal handler was
messing with evsig_base, which can be set from lots of places in the
code. Ordinarly, we'd just stick a lock on it, except that it is
illegal (and genuinely error-prone) to call pthread_mutex_acquire()
from inside a signal handler.
The solution is to only store the fd we write to in a static variable,
write the signal number to the fd, and put evsig_cb in charge of
activating signal events.
I have no idea how we'll cope if we want to enable this to handle
siginfo (where available) in the future.

Warn when using the error-prone EV_SIGNAL interface in an error-prone way. Also, fix a couple of race conditions in signal.c
When using the signal.c signal backend, Libevent currently only allows
one event_base to actually receive signals at a time. (This has been
the behavior since at least 1.4 and probably much earlier.) Now, we
detect and warn if you're likely to be racing about which signal goes
to which thread.
We also add a lock to control modifications of the evsig_base field,
to avoid race conditions like those found by Jason Toffaletti.
Also, more comments. Comments are good.

Declare signal handler function as "__cdecl" on Windows.
I swear, they must have half a dozen different calling conventions.
(goes to check)
Holy crud. They actually do. There's __cdecl, __stdcall, __fastcall,
"thiscall", "naked" and the obsolete "__pascal", "__fortran", and
"__syscall". And don't forget WINAPI and __far.
Anyways, this should fix 3044488 if I got it right.

Clean up properly when adding a signal handler fails.
Previously, when a signation() or signal() call failed, we would free
the element we added to sh_old, but not actually clear the pointer.
This would leave a dangling pointer in sh_old that could cause a
crash later.

Replace EVUTIL_CLOSESOCKET macro with a function
The EVUTIL_CLOSESOCKET() macro required you to include unistd.h in your
source for POSIX. We might as well turn it into a function: an extra
function call is going to be cheap in comparison with the system call.
We retain the EVUTIL_CLOSESOCKET() macro as an alias for the new
evutil_closesocket() function.

Fix memory-leak of signal handler array with kqueue.
It turns out that kqueue_dealloc wasn't calling evsig_dealloc()
(because it doesn't use the main signal handler logic) so the sh_old
array was leaking.
This patch also introduces a fix in evsig_dealloc() where we set
the sh_old array to NULL when we free it, so that main/fork can pass.

Try to contain the failure when we are running without socketpair().
Some win32 systems (mostly those using Kaspersky, it would seem)
prevent us from faking socketpair(). This makes our signal
notification code just not work. Our response since 1.4 has been to
assert. For users who would rather work without signals than not work
at all, this has been a regression from 1.3e.
This patch makes adding signal events fail in this case; there's no
reason to kill the whole process.

On win32, errno is not the last socket error. Worse, WSAGetLastError() is not the last socket error sometimes (i.e., EWOULDBLOCK). Also, strerror() does not handle winsock errors. Therefore, event_err() and event_warn() are completely wrong for windows socket errors. Fix that.
