php-src/ext/sockets/sockets.c
David Walker 7373ce9149 Fix #72733: Expose getaddrinfo C function, and supporting connect/bind 
Feature request was to expose getaddrinfo().  I accomplish this
by having an array of resources that are the addrinfo structures.
The resources can be used in new functions to connect/bind, and
one function to examine the contents of the resource.
