413628a7e3 MFp4:
Bring in updated jail support from bz_jail branch.

This enhances the current jail implementation to permit multiple
addresses per jail. In addtion to IPv4, IPv6 is supported as well.
Due to updated checks it is even possible to have jails without
an IP address at all, which basically gives one a chroot with
restricted process view, no networking,..

SCTP support was updated and supports IPv6 in jails as well.

Cpuset support permits jails to be bound to specific processor
sets after creation.

Jails can have an unrestricted (no duplicate protection, etc.) name
in addition to the hostname. The jail name cannot be changed from
within a jail and is considered to be used for management purposes
or as audit-token in the future.

DDB 'show jails' command was added to aid debugging.

Proper compat support permits 32bit jail binaries to be used on 64bit
systems to manage jails. Also backward compatibility was preserved where
possible: for jail v1 syscalls, as well as with user space management
utilities.

Both jail as well as prison version were updated for the new features.
A gap was intentionally left as the intermediate versions had been
used by various patches floating around the last years.

Bump __FreeBSD_version for the afore mentioned and in kernel changes.

Special thanks to:
- Pawel Jakub Dawidek (pjd) for his multi-IPv4 patches
  and Olivier Houchard (cognet) for initial single-IPv6 patches.
- Jeff Roberson (jeff) and Randall Stewart (rrs) for their
  help, ideas and review on cpuset and SCTP support.
- Robert Watson (rwatson) for lots and lots of help, discussions,
  suggestions and review of most of the patch at various stages.
- John Baldwin (jhb) for his help.
- Simon L. Nielsen (simon) as early adopter testing changes
  on cluster machines as well as all the testers and people
  who provided feedback the last months on freebsd-jail and
  other channels.
- My employer, CK Software GmbH, for the support so I could work on this.

86b3e19077 - Add support for interrupt bindig to cpuset(1). Interrupts are bound
by specifying the interrupt with -x <irq>.  The irq number matches
   those displayed by vmstat -i.

cffe6e824b - When running a new command cause cpuset to operate on the per-thread mask
by default rather than the setmask.  This is consistent with the linux
   tool and more consistent with the notion that the default level is
   the process level.  The cpuset mask can still be modified by specifying
   the -c option.  You can not set the per-thread and cpuset mask in
   a single command.
 - Update the man page to reflect this change.

7be5912e3f - Remove the -i argument when running a command to simplify things a
little bit and to prevent users from specifying a private mask that may
   later restrict other group changes.
 - Add a man page which brueffer generously contributed to.

73c40187fd - Verify that when a user supplies a mask that is bigger than the kernel
mask none of the upper bits are set.
 - Be more careful about enforcing the boundaries of masks and child sets.
 - Introduce a few more CPU_* macros for implementing these tests.
 - Change the cpusetsize argument to be bytes rather than bits to match
   other apis.

0d985e498d Add a simple utility for manipulating cpusets. Man page will be available
soon.
 - Lists of cpus may be specified with -l with ranges specified as low-high and
   commas between individual cpus and ranges.  ie -l 0-2,4,6-8.
 - cpuset can modified -p pids, -t tids, or -s cpusetids.
 - cpuset can -g get the current mask for any of the above.
