ZTS fix.

Added bindto socket context option.

Make new poll stuff work on win32 (and still be safe on unix)

Fix for Bug #24189: possibly unsafe select(2) usage.
We avoid the problem by using poll(2).

On systems without poll(2) (older bsd-ish systems, and win32), we emulate
poll(2) using select(2) and check for valid descriptors before attempting
to access them via the descriptor sets.

If an out-of-range descriptor is detected, an E_WARNING is raised suggesting
that PHP should be recompiled with a larger FD_SETSIZE (and also with a
suggested value).

Most uses of select(2) in the source are to poll a single descriptor, so
a couple of handy wrapper functions have been added to make this easier.

A configure option --enable-fd-setsize has been added to both the unix and
win32 builds; on unix we default to 16384 and on windows we default to 256.
Windows FD_SETSIZE imposes a limit on the maximum number of descriptors that
can be select()ed at once, whereas the unix FD_SETSIZE limit is based on the
highest numbered descriptor; 256 should be plenty for PHP scripts under windows
(the default OS setting is 64).

The win32 specific parts are untested; will do that now.

Fix a bug in the persistent socket liveness checks and feof(); they were
using the default socket timeout of 60 seconds before returning the socket
to the calling script. The reason they were using that value is that the
same code is used for feof(), so the fix is allowing the caller to
indicate the timeout value for liveness checks.

A possible remaining issue now is that 0 second timeout[1] for pfsockopen
is possibly too short; it's impossible to specify a sane value for all
possible uses, so maybe we need a stream context or an .ini option to
control this, or maybe use the timeout value that was passed to
pfsockopen().

# [1] by timeout, I mean the time that PHP will wait for data on a
# persistent socket before deciding if a new connection should be made;
# NOT the timeout while waiting for a new connection to be established.

- A belated happy holidays and PHP 5

this can't be persistent

Removed unused variables.

Add stream_socket_sendto and stream_socket_recvfrom which work very much
like sendto() and recvfrom() syscalls.

(sort of) MFB, feof fix for sockets.

port "liveness" checks and a couple of other things from the 4.3 branch.
Liveness checks are used to validate persistent socket connects when they
are re-used.

Set the EOF indicator after each read attempt.
This prevents it getting stuck in the on position.

Merge selectable descriptor casting from PHP_4_3 branch.

Win32 build fixes for openssl

updating license information in the headers.

Fix warnings.

Add IPv6 support to stream_socket_client/server()
