call with F_FSCTL set and F_SETFL calls generate calls to a new
fileop fo_fcntl. Add genfs_fcntl() and soo_fcntl() which return 0
for F_SETFL and EOPNOTSUPP otherwise. Have all leaf filesystems
use genfs_fcntl().

shutdown:
During an unmount, wake up all the processes which are waiting to lock
the socket for receive, and wait for them (and the process blocked in
soreceive, if any) to go away before blowing away the socket and the
mount structure.
-arrange gateway code to fall back to the old method if the new "getfile"
is not answered (and both are enabled -- allow to switch off the new
method for symmetry)
-handle error if setting the netmask fails
count is 0, wait for use count to drain before finishing the close.
This is necessary in order for multiple processes to safely share file
descriptor tables.
* Add prototype to libkern.h.
* Remove the almost-identical-copy from libsa/net.[ch].
* Change its type back to the (wrong, but harmless) historical one. (u_long)
* Kill the XXX local prototype in nfs_bootparam.c
* We shouldn't truncate the file.
* We were leaving the vnode locked (unless the truncate happened to fail).
Solaris clients may cause this under some conditions.
Problem reported by chopps, analysis and fix by me.
interface and the address allocated, to roll everything back if the
mount fails:
-put an interface pointer into "struct nfs_diskless" to have it
available for cleanup, don't pass it around anymore where the
"struct nfs_diskless" is already passed
-add a "cleanup" function which shuts the interface down
-in the protocol-specific parts, either return with "everything
ready" or "completely shut down"
-use common functions for interface initialization and shutdown
-add a function to delete all routes associate to an interface
(why is this necessary and not done by ~IFF_UP?)

general cleanup
* Increase the size of sigset_t to accomodate 128 signals -- adding new
versions of sys_setprocmask(), sys_sigaction(), sys_sigpending() and
sys_sigsuspend() to handle the changed arguments.
* Abstract the guts of sys_sigaltstack(), sys_setprocmask(), sys_sigaction(),
sys_sigpending() and sys_sigsuspend() into separate functions, and call them
from all the emulations rather than hard-coding everything. (Avoids uses
the stackgap crap for these system calls.)
* Add a new flag (p_checksig) to indicate that a process may have signals
pending and userret() needs to do the full (slow) check.
* Eliminate SAS_ALTSTACK; it's exactly the inverse of SS_DISABLE.
* Correct emulation bugs with restoring SS_ONSTACK.
* Make the signal mask in the sigcontext always use the emulated mask format.
* Store signals internally in sigaction structures, rather than maintaining a
bunch of little sigsets for each SA_* bit.
* Keep track of where we put the signal trampoline, rather than figuring it out
in *_sendsig().
* Issue a warning when a non-emulated sigaction bit is observed.
* Add missing emulated signals, and a native SIGPWR (currently not used).
* Implement the `not reset when caught' semantics for relevant signals.
Note: Only code touched by the i386 port has been modified. Other ports and
emulations need to be updated.
