NetBSD version is a feature-to-feature re-implementation of GNU gzip using the freely-redistributable zlib and this version is expected to be mostly bug-to-bug compatible with the GNU implementation. - Because this is a piece of mature code and we want to make changes so it is added directly rather than importing to src/contrib. - Connect newly added code to src/usr.bin/ and rescue/rescue build. - Disconnect the GNU gzip code from build for now, they will be eventually removed completely. - Provide two new src.conf(5) knobs, WITHOUT_BZIP2_SUPPORT and WITHOUT_BZIP2. Tested by: kris (full exp-7 pointyhat build) Approved by: core (importing a 4-clause BSD licensed file) Approved by: re (adding new utility during -HEAD code slush)
