The preprocessor macros defined in some header can be checked, using
Autoconf's AC_COMPILE_IFELSE, or with simpler AC_CHECK_DECL(S), or even
better and simpler directly in the C code.
* PHP-5.6:
Use better constant since MAXHOSTNAMELEN may mean shorter name
use right sizeof for memset

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.
