13ccadd4b0 This is what was "fdfix2.patch," a fix for fd sharing. It's pretty
far-reaching in fd-land, so you'll want to consult the code for
changes.  The biggest change is that now, you don't use
	fp->f_ops->fo_foo(fp, bar)
but instead
	fo_foo(fp, bar),
which increments and decrements the fp refcount upon entry and exit.
Two new calls, fhold() and fdrop(), are provided.  Each does what it
seems like it should, and if fdrop() brings the refcount to zero, the
fd is freed as well.

Thanks to peter ("to hell with it, it looks ok to me.") for his review.
Thanks to msmith for keeping me from putting locks everywhere :)

dbafb3660f Simplify the handling of VCHR and VBLK vnodes using the new dev_t:
Make the alias list a SLIST.

        Drop the "fast recycling" optimization of vnodes (including
        the returning of a prexisting but stale vnode from checkalias).
        It doesn't buy us anything now that we don't hardlimit
        vnodes anymore.

        Rename checkalias2() and checkalias() to addalias() and
        addaliasu() - which takes dev_t and udev_t arg respectively.

        Make the revoke syscalls use vcount() instead of VALIASED.

        Remove VALIASED flag, we don't need it now and it is faster
        to traverse the much shorter lists than to maintain the
        flag.

        vfs_mountedon() can check the dev_t directly, all the vnodes
        point to the same one.

Print the devicename in specfs/vprint().

Remove a couple of stale LFS vnode flags.

Remove unimplemented/unused LK_DRAINED;

275d27d822 Previous commit also removed some 'const' qualifiers on args for
svr4_sys_sendto() which probably shouldn't have been 'const'.

c8f2ce34ac Previous commit also finished cleaning up some dev_t -> udev_t transformations
related to the commit for rev 1.3 of svr4_stat.c.
svr4_sysvec.c also received a copyright message (which is why it grew by
28 lines).

f46f4cccb8 Fix svr4_sys_poll(); SysV STREAMS produce return values from poll() which
BSD sockets don't.  Guess at a correct emulation for those values (it seems
to work for telnet, ftp and friends)

6ef6864f94 Fix panic caused when *stat64() family of syscalls try to fill-in
their svr4_stat64 structures with old dev_t values instead of udev_t's.
Panic was caused when major() and minor() were called with args which
weren't pointers.  The panic was probably introduced in rev 1.51 of
kern_conf.c

8f437f4439 Rename struct members sa_siginfo. POSIX reserves identifiers starting
with sa_ when <signal.h> is included. They would conflict with the
upcoming SA_SIGINFO implementation.

f711d546d2 Suser() simplification:
1:
  s/suser/suser_xxx/

2:
  Add new function: suser(struct proc *), prototyped in <sys/proc.h>.

3:
  s/suser_xxx(\([a-zA-Z0-9_]*\)->p_ucred, \&\1->p_acflag)/suser(\1)/

The remaining suser_xxx() calls will be scrutinized and dealt with
later.

There may be some unneeded #include <sys/cred.h>, but they are left
as an exercise for Bruce.

More changes to the suser() API will come along with the "jail" code.
