New user-space functions:
. stream_socket_client() - similar to fsockopen(), but more powerful.
. stream_socket_server() - Creates a server socket.
. stream_socket_accept() - Accept a client connection.
. stream_socket_get_name() - Get local or remote name of socket.

Tidy up some leaks and debug printfs.
Move more streams functions into streamsfuncs.c and streamsfuncs.h.

Another big commit (tm).

Main Changes:
- Implement a socket transport layer for use by all code that needs to open
some kind of "special" socket for network or IPC.
- Extensions can register (and override) transports.
- Implement ftruncate() on streams via the ioctl-alike option interface.
- Implement mmap() on streams via the ioctl-alike option interface.
- Implement generic crypto API via the ioctl-alike option interface.
(currently only supports OpenSSL, but could support other SSL toolkits,
and other crypto transport protocols).

Impact:
- tcp sockets can be overloaded by the openssl capable sockets at runtime,
removing the link-time requirement for ssl:// and https:// sockets and
streams.
- checking stream types using PHP_STREAM_IS_SOCKET is deprecated, since
there are now a range of possible socket-type streams.

Working towards:
- socket servers using the new transport layer
- mmap support under win32
- Cleaner code.

# I will be updating the win32 build to add the new files shortly
# after this commit.

A add much more useful select(2) implementation than is provided by
windows sockets. The winsock implementation will only work with sockets;
our implementation works with sockets and file descriptors.
By association, stream_select() will now operate correctly with files, pipes and sockets.

This change required linking against the winsock2 library. In terms of
compatibility, only older versions of windows 95 do not have winsock2
installed by default. It is available as a redistributable file, and is most likely installed by any OS patches (eg: Internet Explorer) applied by the user.

Also, add a win32 compatible pipe test when opening a stream from a pipe. This test will only work on NT, win2k and XP platforms. Without this test, interleaved fread() and select() calls would cause the read buffer to be clobbered. I will be working on a fix for this issue for win9x.

Potential fixes for #21809 and #22099.

A Simple fix for Bug #12360 (fsockopen timeout doesn't work).

Analysis:
On systems with HAVE_GETADDRINFO and IPV6 support, php_hostconnect would
attempt to connect to each possible address that matched the requested IP.

If the remote host:port combination are dropping packets this would cause the
first connection to timeout (after waiting for the full timeout duration).

PHP would then attempt the second address and wait the full duration again.

Solution:
If the first connection attempt times out, abort the connection loop.

Fix for #19508 by poleson@verio.net.

Silence compile warning, when compiling --with-openssl.

Fixed a typo.

Revert my last bogus commit.
Change the comparison to something that is less likely to inspire me to
make the same mistake again...

Improve EOF detection. Fixes #19970.

Implement better SSL error handling.

A much better probable fix for #16114.

Probable fix for #16114

(php_socket_errno) win32 errno compatible macro.
(php_socket_strerror) win32 compatible strerror replacement.
Add an E_NOTICE when a socket write fails.

This seems to resolve the issues with fgets.
I've moved EOF detection into the streams layer; a stream reader
implementation should set stream->eof when it detects EOF.
Fixed test for use

Fixed test for user streams - it still fails but that is due to an output

Add a few notes

replace dont_block with a flag.

Improve the general behaviour of stream_gets and fix its semantics
with regard to sockets. The behaviour should be aligned with PHP 4.2 now.
This has been verified to some degree.

Improve the general behaviour of stream_gets and fix its semantics
with regard to sockets. The behaviour should be aligned with PHP 4.2 now.
This has been verified to some degree.

If the underlying stream operations block when no new data is readable,
we need to take extra precautions.

If there is buffered data available, we check for a EOL. If it exists,
we pass the data immediately back to the caller. This saves a call
to the read implementation and will not block where blocking
is not necessary at all.

If the stream buffer contains more data than the caller requested,
we can also avoid that costly step and simply return that data.
