Add _MAXCOMLEN to syslimits, it is 24, and includes the NUL. Following
commits will change sys/param.h MAXCOMLEN, sys/sysctl.h KI_MAXCOMLEN,
sys/acct.h ac_comm[], dev/ic/dtvar.h DTMAXCOMLEN to use this, and also
adapt most to the included NUL correctly. This will allow us to remove
sys/param.h include from userland base.
sys/syslimits.h is chosen as the best place for this define because it
has very small namespace which is already pulled in often.

double ARG_MAX

Back out previous. HOST_NAME_MAX is only defined for newer POSIX
revisions so it is not safe to define MAXHOSTNAMELEN in terms of it.

SEM_VALUE_MAX belongs in <limits.h> (via sys/syslimits.h)
struct sem --> struct __sem (doesn't belong in public namespace)
Zap pointless _KERNEL tests

ok deraadt@

Define _POSIX_HOST_NAME_MAX and HOST_NAME_MAX.

ok krw@, laurent@

Move TTY_NAME_MAX and LOGIN_NAME_MAX to sys/syslimits.h
Use correct values for _POSIX_TTY_NAME_MAX and _POSIX_LOGIN_NAME_MAX
Define MAXLOGNAME in terms of LOGIN_NAME_MAX
OK krw@

First step in include files overhaul. Use __FOO_VISIBLE (as defined
in sys/cdefs.h) instead of _FOO_SOURCE. Also fix several namespace
pollution issues, including the byte order defines. OK deraadt@

Define _POSIX_SYMLINK_MAX and SYMLINK_MAX as _POSIX_PATH_MAX and PATH_MAX
respectively instead of duplicating their values.

Updates based on Single Unix; OK deraadt@
o _POSIX_CHILD_MAX increased to 25
o _POSIX2_RE_DUP_MAX renamed _POSIX_RE_DUP_MAX
o _POSIX_SYMLINK_MAX and SYMLINK_MAX added (same as PATH_MAX)
o _POSIX_SYMLOOP_MAX and SYMLOOP_MAX added (like MAXSYMLINKS)

Remove the advertising clause in the UCB license which Berkeley
rescinded 22 July 1999. Proofed by myself and Theo.

branches: 1.5.8;
Add IOV_MAX from XPG 4.2. This supercedes UIO_MAXIOV so mark it as such.

move NZERO for XPG3; kleink

Added #ifndef RE_DUP_MAX around the macro definition; CVS ended up
using this value, when it's supposed to use the one defined in
lib/regex.h

It also gets rid of a compilation warning.
