Mark Johnston 2f28ceeb34 Bind ip/tcp/udp provider translators and symbols to the same versions as in 
illumos, rather than using "1.0" everywhere.

Some of the translators use D functions that are not present in version
1.0 (e.g. inet_ntoa()) which can result in libdtrace crashing when running
scripts that restrict themselves to version 1.0
(e.g. with "-x version=1.0").
