Service happy. Code in libc attempts to open files in the ns filesystem, and

- Add a new vnode flag VEXECMAP, which indicates that a vnode has

executable mappings. Stop overloading VTEXT for this purpose (VTEXT
also has another meaning).
- Rename vn_marktext() to vn_markexec(), and use it when executable
mappings of a vnode are established.
- In places where we want to set VTEXT, set it in v_flag directly, rather
than making a function call to do this (it no longer makes sense to
use a function call, since we no longer overload VTEXT with VEXECMAP's
meaning).

Do address family (AF_*) number translation for socket system calls which

Change sendmsg()/recvmsg() to expect the control information
to be passed the standard way (not 4.3BSD one, imlied by compat_43 code
or MSG_COMPAT). Linux uses different (arguably broken) CMSG_ALIGN() on some
architectures unfortunately, that would need to be handled eventually.
Also provide some other trivial stubs (like linux_sys_send()) to avoid
unneeded dependance on uipc_syscalls_43.c.

Add entry for flock() syscall.
...
From the NetBSD and OSF man pages, the arguments and operation of the
2 flocks are identical. The only differences are in some of the possible
values for errno which may be set in the event of certain errors. These
differences are (again from the manual pages):
The NetBSD flock may set errno to
[EOPNOTSUPP] The argument fd refers to an object other than a file.
and the OSF flock doesn't list this is a possible error code.
The OSF flock may set errno to:
[EINTR] A signal interuppted the flock call.
[ENOLCK] The lock table is full. Too many regions are already locked.
[EDEADLK] The lock is blocked by some lock from another process. Putting
the calling process to sleep while waiting for that lock to
become free would cause a deadlock.
while the NetBSD flock does not list these as possibilities.
The remainder of the possible error codes are the same.
commit cleared with thorpej first.

Linux does not send a SIGIO to the write end of a socket,
...
neither it does send any SIGIO for pipes. If async I/O
was requested, we keep the SS_ASYNC in struct socket flag
set, but we clear SB_ASYNC flags on the sending buffer
(for socket), and on the sending and the receiving buffer
(for pipes).
Because we do not alter to SS_ASYNC in struct socket,
the Linux process keeps a consistent view of async I/O
status if it attemps to read the async flag (SS_ASYNC)
This async I/O problem does matters, since some Linux
a programs such as the JDK request async I/O on pipes,
but they fail if they happen to get a SIGIO to the write
end of the pipe.

Fix a partial construction problem that can cause race conditions
...
between creation of a file descriptor and close(2) when using kernel
assisted threads. What we do is stick descriptors in the table, but
mark them as "larval". This causes essentially everything to treat
it as a non-existent descriptor, except for fdalloc(), which sees a
filled slot so that it won't (incorrectly) allocate it again. When
a descriptor is fully constructed, the code that has constructed it
marks it as "mature" (which actually clears the "larval" flag), and
things continue to work as normal.
While here, gather all the code that gets a descriptor from the table
into a fd_getfile() function, and call it, rather than having the
same (sometimes incorrect) code copied all over the place.
