b1bf661000 [Add missing files from previous commit]
Major changes to the generic device framework for FreeBSD/alpha:

* Eliminate bus_t and make it possible for all devices to have
  attached children.

* Support dynamically extendable interfaces for drivers to replace
  both the function pointers in driver_t and bus_ops_t (which has been
  removed entirely.  Two system defined interfaces have been defined,
  'device' which is mandatory for all devices and 'bus' which is
  recommended for all devices which support attached children.

* In addition, the alpha port defines two simple interfaces 'clock'
  for attaching various real time clocks to the system and 'mcclock'
  for the many different variations of mc146818 clocks which can be
  attached to different alpha platforms.  This eliminates two more
  function pointer tables in favour of the generic method dispatch
  system provided by the device framework.

Future device interfaces may include:

* cdev and bdev interfaces for devfs to use in replacement for specfs
  and the fixed interfaces bdevsw and cdevsw.

* scsi interface to replace struct scsi_adapter (not sure how this
  works in CAM but I imagine there is something similar there).

* various tailored interfaces for different bus types such as pci,
  isa, pccard etc.

25874f75bc Don't define away __attribute__() for the non-gcc and old-gcc cases.
Using __attribute__() in non-ifdefed code is just wrong if it changes
the semantics, and there is no way to ignore __attribute__() only in
the benign cases.

Don't use __attribute__ in non-ifdefed code here.  It was a benign
case, but we already have a macro (__unused) for this case.

Expanded comment about gotchas for __CONCAT() in the non-ANSI case.

a395dbb153 Avoid a 64-bit division in procfs_readdir(). Fixed related overflows.
Check args using the same expression as in fdesc and kernfs.  The check
was actually already correct, modulo overflow.  It could be tightened
up to either allow huge (aligned) offsets, treating them as EOF, or
disallow all offsets beyond EOF.

Didn't fix invalid address calculation &foo[i] where i may be out of
bounds.

Didn't fix shooting of foot using a private unportable dirent struct.

02a93d74e0 Don't compile in the use of poll() when building libc_r. This isn't
so much a "fix", rather a bandaid to buy time to fix it properly

a41878a77a Avoid a 64-bit division in fdesc_readdir(). Fixed related overflows
and missing arg checking.

Panic instead of returning bogus error codes or forgetting to check
all cases if fdesc_readdir() gets called for a non-directory.  This
can't happen.

eee772ec70 Deal with PROTO_IGMP and PROTO_IPIP packets correctly.
Submitted by: Mark Tinguely <tinguely@plains.NoDak.edu>
  This change will allow a PPP host enabled with the "-alias" option to
  run mrouted. This does not intend to forward the IGMP nor tunneled packets
  to another host on the far side if the tun0 interface.

42c57c8682 o Pass our negotiated number of VJ slots into
sl_uncompress_tcp() and drop packets with
  slot numbers that are out of range.
o Drop packets that want to use a slot that still
  has an IP header length of 0 (ie, the requested
  slot number is bogus again).

Without this code, if the other side mis-behaves (and
sends us garbage slot numbers), we happily ``adjust''
a memset(..., '\0', ...) TCP/IP header and promptly
cr*p all over the stack before returning.... quickly
followed by a SIGBUS.

Dodgy ISP used by, and help locating the problem from: jmz
Problem also seen by: Mourad de Riche <omnibus@image.dk>

There's still a link lockup after this happens, but my
bets are on the other side (who has already started sending
rubbish) being to blame.

e2fea9c587 join(1) is used by lorder, add it to build-tools. (otherwise, things get
ugly when an a.out /usr/bin/join sees the elf LD_LIBRARY_PATH from a
'make world' and it's a.out ld.so tries to load the elf libc.so.)

aa75cb86b4 Fix the case when renaming to a file that you've just created and deleted,
that had an inode that has not yet been written to disk, when the inode of the
new file is also not yet written to disk, and your old directory entry is not
yet on disk but you need to remove it and the new name exists in memory
but has been deleted but the transaction to write the deleted name to disk
exists and has not yet been cancelled by the request to delete the non
existant name.  I don't know how kirk could have missed such a glaring
problem for so long. :-) Especially since the inconsitency survived on
the disk for a whole 4 second on average before being fixed by other code.
This was not a crashing bug but just led to filesystem inconsitencies
if you crashed.

ff0f9439b4 o Maintain a link-type mask for open datalinks as well as
for all datalinks in a bundle.  Ppp now deals correctly
  with link types that are changed while open
o When changing the type of the last AUTO link, only clear
  the interface if we're not in PHASE_NETWORK.  This allows
  us to switch to -ddial mode while we have a connection
  without suddenly unexpectedly throttling ourselves by
  clearing the interface configuration.
