Implement nofollow (l) for fopen(3).

Add 'x' to the mode bits to specify O_EXCL, like glibc.

- ansify, knf.
- no functional changes

* Arrange for interfaces that create new file descriptors to be able to
set close-on-exec on creation (http://udrepper.livejournal.com/20407.html).

- Add F_DUPFD_CLOEXEC to fcntl(2).

* Arrange for interfaces that create new file descriptors to be able to
set close-on-exec on creation (http://udrepper.livejournal.com/20407.html).

- Add F_DUPFD_CLOEXEC to fcntl(2).
- Add MSG_CMSG_CLOEXEC to recvmsg(2) for unix file descriptor passing.
- Add dup3(2) syscall with a flags argument for O_CLOEXEC, O_NONBLOCK.
- Add pipe2(2) syscall with a flags argument for O_CLOEXEC, O_NONBLOCK.
- Add flags SOCK_CLOEXEC, SOCK_NONBLOCK to the socket type parameter
for socket(2) and socketpair(2).
- Add new paccept(2) syscall that takes an additional sigset_t to alter
the sigmask temporarily and a flags argument to set SOCK_CLOEXEC,
SOCK_NONBLOCK.
- Add new mode character 'e' to fopen(3) and popen(3) to open pipes
and file descriptors for close on exec.
- Add new kqueue1(2) syscall with a new flags argument to open the
kqueue file descriptor with O_CLOEXEC, O_NONBLOCK.

* Fix the system calls that take socklen_t arguments to actually do so.

* Don't include userland header files (signal.h) from system header files
(rump_syscallargs.h).

* Bump libc version for the new syscalls.

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22280, verified by myself.

Merge the nathanw_sa branch.

add and "f" flag to fopen that makes sure we are opening a plain file,
so that there is no chance to block.

back out the #ifdef _DIAGNOSTIC argument checks; too many people complained.
_DIAGASSERT() is still retained.

* use _DIAGASSERT() to check pointer arguments against NULL and file
descriptors against -1 (as appropriate).
* add actual checks which to detect stuff that would trigger_DIAGASSERT(),
and attemp

* use _DIAGASSERT() to check pointer arguments against NULL and file
descriptors against -1 (as appropriate).
* add actual checks which to detect stuff that would trigger_DIAGASSERT(),
and attempt to return a sane error condition.
* knf some code
* remove some `register' decls.

the first two items result in the addition of code similar to the
following in various functions:

_DIAGASSERT(path != NULL)
#ifdef _DIAGNOSTIC
if (path == NULL) {
errno = EFAULT;
return (-1);
}
#endif

include <fcntl.h> instead of <sys/file.h>

remove obsolete register declarations

Fix RCSID's
Fix gcc warnings.
Add prototypes for functions that were declared in more than one place
to local.h or extern.h and use that instead.

pull in local.h for prototypes. first arg to __sflags() is const char *

Merged with 4.4lite.
Changed to conform to NetBSD's new RCS Id convention.

Add explicit return types to function definitions.

Declare rcsid strings so they are stored in text segment.

Add RCS identifiers.
