When using this flag, the input file is kept after
compression or decompression, this makes our gzip
more compatible with the other gzip
changes reworked by jca@, thanks

value < 0. errno is only updated in this case. Change all (most?)
callers of syscalls to follow this better, and let's see if this strictness
helps us in the future.

Fixes a directory traversal bug when the stored name includes a
directory component. Both GNU gzip and our gzip store the basename
of the path when compressing but a malicious .gz file could contain
an arbitrary path. Problem found by elvis alien. OK deraadt@

but some of the write code remained. shuffle things around a bit to make
the exclusion more complete.

because of excessive code sharing. compression and decompression are not
entirely similar, they should share less.

for the read (inflate) case where there might be multiple streams.
For the write (deflate) case there can only be a single stream so
just use the per-stream total_in/total_out. Fixes "gzip -v" byte
counts. OK henning@.

it allows chown(2) call to change the user or group on a file.
- usr.bin/compress : aka gzip
- usr.bin/mg : open a file for writing
- usr.bin/sed : inplace editing
- usr.bin/sort : if outfile equals one of the input files

correctly - logically complete that now by removing MLINKS from base;
authors need only to ensure there is an entry in NAME for any function/
util being added. MLINKS will still work, and remain for perl to ease
upgrades;

in cat mode (-c, zcat), or in test mode (-t), or if there are no
file arguments and there is no -o outfile. Due to fts(3) we require
rpath even for compress <in >out.

system behaviours such as forking, execve, sockets, etc.
in theory this extended by parsing the arguments first, and creating
the whitepathlist. the pathlist probably needs to be directory-oriented,
rather than exact path of files, because a gzip file may specify the
filename it wants (and that won't be available until it is opened, and
partially parsed). anyone want to give this a try?
gzip was an early goal for capsicum. who is running a capsicum gzip?

Not bugs in short-lived commands that call exit() -> _exit() immediately,
but for idempotency.
Originally found in ls(1) by Valgrind. Changes for other commands are
from deraadt@. Reviewed by me, tested in snapshots.

Prefer to set attributes by fd for regular files, and not follwing
symlinks for others.

possible. Annotate <sys/param.h> lines with their current reasons. Switch
to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_NAME_MAX, etc. Change
MIN() and MAX() to local definitions of MINIMUM() and MAXIMUM() where
sensible to avoid pulling in the pollution. These are the files confirmed
through binary verification.

Replace malloc() and realloc() calls that may have integer overflow in the
multiplication of the arguments with reallocarray().

When you don't get what you asked for, you get angry.
When you add a tiny bit, it should be "more" or "less" still,
or you'll get angry.
So lets make zmore(1) call more(1) and zless(1) call less(1),
as it's supposed to be.
okay and input from ingo@, no objections from author AKA millert@

come from GNU zip and they were never in compress(1) until we added
gzip(1) support to it. Also remove -g flag from gzip(1) as it is
non-standard and only makes sense in compress(1).

- kill an unneccessary Pp that created double vertical space
- mention that posix marks these apps xsi
- add uncompress -V to the list of extensions
- document that posix stipulates a limit of 14 for -b, even though it
permits 15 and 16
