| | | | | | | | | | | | | | not optimal from a performance standpoint since the write buffer is not necessarily be filled up when the inflate rountine reached the end of input buffer and it's not the end of file. This problem gets uncovered by trying to pipe gunzip -c output to a GEOM device directly, which enforces the writes be multiple of sector size. Sponsored by: iXsystems, Inc.

| | | | | | | | | | | | | | - Limit suffix to be no more than 30 bytes long. This matches GNU behavior. - Correct usage of memcpy().

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)
