354ed04257 In gunzip(1), treat trailing garbage as a warning and not an error. This
allows scripts to distinguish it between real fatal errors, for instance a
CRC mismatch.

Update manual page for the behavior change.

fc26891004 Match symbolic link handling behavior with GNU gzip, bzip2 and xz:
When we are operating on a symbolic link pointing to an existing
file, bail out by default, but go ahead if -f is specified.

2a8e7ac9c8 Add a '-k' flag which is similar with its bzip2(1) counterpart,
meaning that the user wants the input file to be left intact.

9a9ea25f4a Replace the GNU gzip with a slightly modified NetBSD gzip. The
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)
