When system calls indicate an error they return -1, not some arbitrary
value < 0. errno is only updated in this case. Change all (most?)
callers of syscalls to follow this better, and let's see if

Prefer <fcntl.h> over <sys/fcntl.h> in userland
While here, delete some extra #includes and apply style(9) sort rules.

ok deraadt@ krw@ mpi@

Use pledge "disklabel" as needed. The theory here is these tools become more
resistant against memory correctup, if a corrupt filesystem is given to them.
ok krw

After the disk is opened, this can pledge "stdio".

Adjust <sys/param.h> comments regarding use of use of MAXFRAG, or
delete <sys/param.h> if now possible
ok guenther

Replace <sys/param.h> with <limits.h> and other less dirty headers where
possible. Annotate <sys/param.h> lines with their current reasons. Switch
to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_N

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.

final removal of daddr64_t. daddr_t has been 64 bit for a long enough
test period; i think 3 years ago the last bugs fell out.
