Fix ext/sockets build with phpize

Fixes bug #64285

Cleanup some multicast code; fix for mac os x?

When I moved some stuff from sockets.c to multicast.c, I did not copy
some conditional defines for systems without the RFC 3678 API.

Cleanup some multicast code; fix for mac os x?

When I moved some stuff from sockets.c to multicast.c, I did not copy
some conditional defines for systems without the RFC 3678 API.

I moved such defines to multicast.h so both sockets.c and multicast.c
can benefit from them and I prefixed them with PHP_ so that it's less
confusing: now PHP_MCAST_* are defined to either the MCAST_* RFC 3678
APIs or to legacy APIs and MCAST_* always mean the (possibly undefined)
system definitions.

Move macro back to .c file

Because it depends on a static function on that .c file.

send/recvmsg() support for Windows

Build fixes; accept names for if_index

Support sticky IPV6_PKTINFO

Rename some functions for consistency

Move some multicast stuff to multicast.c

Register extra MSG_* constants

Redactor to expose socket_import_file_descriptor()

Improve imported socket family detection

Also added constant SO_FAMILY.

Add IPV6_UNICAST_HOPS option constant.

Wrap recvmsg() and sendmsg()

This introduces two new functions:

int socket_recvmsg(resource $socket, array &$msghdr, int $flags)
int socket_sendmsg(resource $socket, array $msgh

Wrap recvmsg() and sendmsg()

This introduces two new functions:

int socket_recvmsg(resource $socket, array &$msghdr, int $flags)
int socket_sendmsg(resource $socket, array $msghdr, int $flags)

The arrays representing struct msghdr follow the native counterpart
closely: structs are mapped to arrays, fields to array elements whose
key is the name of the field without the prefix (e.g. "name" instead
of "msg_name") and array are mapped to sequential numeric PHP arrays.

Right now the only type of ancillary data supported is fot the
level/type pair IPPROTO_IPV6/IPV6_PKTINFO.

I also refactored out the name resolution functions and made
sockets_strerror() a global function.

Bug #49341: Add SO_REUSEPORT support for socket_set_option()

This is a BSD-only feature, and it will only be available on BSD.
On other platforms the constant will simply not be set.

Fixed sockets ext build on win

Use if_nametoindex in Vista

I missed this instance in bf19838c.
