Put the different implementations of "pcap_findalldevs()" into separate

source files, rather than having a pile of #ifdefs in "inet.c".  Add
code to the configure script to determine which implementation to use on
the platform for which libpcap is being built.

Add a "pcap_findalldevs()" implementation for Solaris 8 and later that
handles IPv6 addresses.
