Make canon-host require getaddrinfo. * m4/canon-host.m4 (gl_CANON_HOST): Remove most dependencies. AC_LIBSOURCE canon-host.h. Call... (gl_PREREQ_CANON_HOST): ...this new function, which requires gl_GETADDRINFO. * m4/getaddrinfo.m4 (gl_GETADDRINFO): Compile gai_strerror when needed. Return usable errors from canon-host. * lib/canon-host.h: New file. * lib/canon-host.c (canon_host): Wrap... (canon_host_r): ...this new function, which now relies exclusively on getaddrinfo. (ch_strerror): New function. (last_cherror): New global. * lib/getaddrinfo.c: Move include of getaddrinfo.h first to test interface. (getaddrinfo): Add AI_CANONNAME functionality. Don't do arithmetic on void *. (freeaddrinfo): Free ai->ai_canonname when set.
