2bc21ed985 Hopefully improve control message passing over Unix domain sockets.
1) Allow the sending of more than one control message at a time
over a unix domain socket. This should cover the PR 29499.

2) This requires that unp_{ex,in}ternalize and unp_scan understand
mbufs with more than one control message at a time.

3) Internalize and externalize used to work on the mbuf in-place.
This made life quite complicated and the code for sizeof(int) <
sizeof(file *) could end up doing the wrong thing. The patch always
create a new mbuf/cluster now. This resulted in the change of the
prototype for the domain externalise function.

4) You can now send SCM_TIMESTAMP messages.

5) Always use CMSG_DATA(cm) to determine the start where the data
in unp_{ex,in}ternalize. It was using ((struct cmsghdr *)cm + 1)
in some places, which gives the wrong alignment on the alpha.
(NetBSD made this fix some time ago).

This results in an ABI change for discriptor passing and creds
passing on the alpha. (Probably on the IA64 and Spare ports too).

6) Fix userland programs to use CMSG_* macros too.

7) Be more careful about freeing mbufs containing (file *)s.
This is made possible by the prototype change of externalise.

99d300a1ec - FDESC, FIFO, NULL, PORTAL, PROC, UMAP and UNION file
systems were repo-copied from sys/miscfs to sys/fs.

- Renamed the following file systems and their modules:
  fdesc -> fdescfs, portal -> portalfs, union -> unionfs.

- Renamed corresponding kernel options:
  FDESC -> FDESCFS, PORTAL -> PORTALFS, UNION -> UNIONFS.

- Install header files for the above file systems.

- Removed bogus -I${.CURDIR}/../../sys CFLAGS from userland
  Makefiles.

73dd316734 mount* fixes from Martin Blapp <mb@imp.ch>:
Made mount more userfriendly (bad slashes are now filtered out)
        and we remove in mount_nfs trailing slashes if there are any.

        Fixed mount_xxx binarys to resolve with realpath(3)
        the mountpoint.

        Translate the deprecated nfs-syntax with '@' to ':' .
        The ':' syntax has now precedence, but '@' still works.
        Notify the user that the '@' syntax should not be used.

eaa86f9d7f Don't use __dead or __pure in user code. They were obfuscations
for gcc >= 2.5 and no-ops for gcc >= 2.6.  Converted to use __dead2
or __pure2 where it wasn't already done, except in math.h where use
of __pure was mostly wrong.

5e074e31a2 Get rid of the last vestiges of the old MOUNT_* constants in the
mount_* programs.  While we're at it, collapse the four now-identical
mount programs for devfs, fdesc, kernfs, and procfs into links to
a new mount_std(8) which can mount any really generic filesystem
such as these when called with the appropriate argv[0].

Also, convert the mount programs to use sysexits.h.

a07c2891bf Bugfixes :
- in mount_portal.c: included catching of SIGHUP to get portald to
  re-read the config file.

  - in mount_portal.c: in SIGCHLD handler the return values checked from
  waitpid were wrong. Note. this routine was written correclty according
  to the manual page for 4.4BSD, but waitpid does not exhibit this
  behaviour. It is not returning 0 when WNOHANG is specified. I havent
  checked this properly.

  - in mount_portal.c: initialized the fdset for the select properly.

  - in mount_portal.c: corrected poor casting in the select.

  - in mount_portal.c: changed a break; to exit (0); so that the
  children die after doing the hard work, this stops the select: bad
  file descriptor messages.

  - in pt_file.c: the kernel passes kernel style open flags to the
  portal code which aren't compatible with "normal" O_ flags. I have
  adjusted these in pt_file.c. In general I think the portal fs code
  and portal_cred structure need changing to pass to the portald
  the right style of flags _and_ the permissions.

  - in pt_tcp.c: a few mistakes in typing of the socket structures,
  getservbyname returns the port number as an int but sockaddr wants
  the port number as an u_short.

  - in pt_tcp.c: someone wrote this on a VAX/Sun whatever and forget
  about byte ordering!! I've included a few htons about the place.

  - in all the above I have sprinkled a few more debugging printf's.

3fa88dec7f Add support for filesystem-specific `-o' options, and re-implement the
most common cd9660 and nfs options like God intended them.  (It is now
possible to say

	mount -o ro,soft,bg,intr there:/foo/bar /foo/bar

again.)  This whole getmntopt() business is an incredible botch;
it never should have been anything more than a wrapper around
getsubopt(3).  Because if the way the current hackaround is implemented,
options which take arguments (like the old `rsize' and `wsize') are still
unavailable, and must be accessed the new, broken way.

(It's unimaginable how Berkeley managed to screw up one of the few things
about NFS that Sun actually got right to begin with!)
