Move ISO88025 source routing information into sockaddr_dl's sdl_data
field. This returns the sdl_data field to a variable-length field. More
importantly, this prevents a easily-reproduceable data-corruption bug when
the interface name plus the hardware address exceed the sdl_data field's
original 12 byte limit. However, token-ring interfaces may still overflow
the new sdl_data field's 46 byte limit if the interface name exceeds 6
characters (since 6 characters for interface name plus 6 for hardware
address plus 34 for source routing = the size of sdl_data). Further
refinements could overcome this limitation but would break binary
compatibility; this commit only addresses fixing the bug for
commonly-occuring cases without breaking binary compatibility with the
intention that the functionality can be MFC'ed to -stable.

Re-remove kern_random.c and svr4_signal.c. Somehow dillon managed to keep
on committing to these while they were in the Attic after they had been
removed. I think this was because he had the file checked out and already
'modified' while markm cvs rm'ed them, and cvs screws up when trying to
"merge" the modifications with the "rm". And after that the client
state was sufficiently hosed to keep it messed up. Yay CVS! (CVS is
very fragile for adding and removing files remotely)

Add a -i option to sed(1) to do inplace editing, to give us an alternative to
Perl for such things. The key difference to Perl is that a backup extension
*MUST* be specified, because on one hand it isn't recommended to have options
which optionally take a parameter, and on the other hand, it'd be slightly
unpleasent to implement proper handling for that.
The difference between this and the version posted to developers@ is that it
does handle multiple files in argv after the getopt(3) handling "correctly",
in that the inplace editing-specific code has been moved out to a function,
and that function is used beyond the first file in our linked list.
This option has been documented as FreeBSD-specific in the manpage.

MFOpenBSD: ibss and ibss-master.
ibss is the modern ad-hoc mode. ibss-master is the same, except that
it creates the ibss network. This distinction is necessary because
some supported cards (symbol) support the former without supporting
the latter.
A seprate commit will introduce a demo-adhoc mode so that we can
disentwingle the multiple, mutually exclusive meandings of adhoc in
the present state of affairs.

Switch from just holding the interlock to holding the standard lock throughout
getnewvnode(). This is safer. In the future, we should investigate requiring
only the interlock to get the vnode object.
Make funsetown() take a 'struct sigio **' so that the locking can
be done internally.
Ensure that no one can fsetown() to a dying process/pgrp. We need
to check the process for P_WEXIT to see if it's exiting. Process
groups are already safe because there is no such thing as a pgrp
zombie, therefore the proctree lock completely protects the pgrp
from having sigio structures associated with it after it runs
funsetownlst.
Add sigio lock to witness list under proctree and allproc, but over
proc and pgrp.

Hold the currently selected vnode's lock across the call to VOP_GETVOBJECT.
Don't try to create a vm object before the file system has a chance to finish
initializing it. This is incorrect for a number of reasons. Firstly, that
VOP requires a lock which the file system may not have initialized yet. Also,
open and others will create a vm object if it is necessary later.

Fix a couple of problems which could cause panics at runtime:
+ setting a bandwidth too large for a pipe (above 2Gbit/s) could
cause the internal representation (which is int) to wrap to a
negative number, causing an infinite loop in the kernel;
+ (see PR bin/35628): when configuring RED parameters for a queue,
the values are not passed to the kernel resulting in panics at
runtime (part of the problem here is also that the kernel does
not check for valid parameters being passed, but this will be
fixed in a separate commit).
These are both critical fixes which need to be merged into 4.6-RELEASE.
