Move wire_test to standalone tool with man page and such...
The following discussion from !4006 (closed) should be addressed:
We did this a while ago, but I had to revert it (see commit e45be9d1). It's used for fuzz testing as well as system tests. I also use it myself sometimes for converting DNS data to and from wire format, and I know I'm not the only one because someone at infoblox asked me to restore it as part of the regular build instead of the test build.
Rather than moving it to bin/tests/system I wonder if we should consider putting it in bin/tools, like we did with named-journalprint or named-rrchecker or nsec3hash.
