MFH: initialize memory

- MFH: Fixed bug #46082 (stream_set_blocking() can cause a crash in some circumstances)

- MFH:
- drop bindlib usage on windows
- inet_pton, inet_ntop and inet_aton are always available (VC9 uses the CRT implementation, VC6 our own)

MFH: silence warning

MFH: fix segfault - error_string may be NULL, in this case we have to follow the old behavior

char **error_message was passed but not used. This causes problems in cases
of getaddrinfo() failure, because the upper layers don't get the error.
initialize a variable because we were readi

initialize a variable because we were reading initialized in case of error.

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

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.
