Spent the day working on backwards compatability using getaddrinfo()
Moved getaddrinfo.? and gethostbyname.? from lib/ to plugins/ due to problems with compiling into the libnagiosplug.a as it required linking against socket libraries which are unneeded except for network based plugins. This code should hopefully happily work for all systems and has been tested prior to commit on Debian GNU/Linux, SPARC Solaris 7 and SPARC Solaris 9. git-svn-id: https://nagiosplug.svn.sourceforge.net/svnroot/nagiosplug/nagiosplug/trunk@424 f882894a-f735-0410-b71e-b25c423dba1c
