Rewrite cpudep_ap_bootstrap(). We now enable L3, L2, L1D and L1I
caches if not yet enabed. This is required for coherency and
atomic operations to work, not to mention performance. We use the
L2 and L3 cache settings of the BSP to configure the APs caches.
Can't be bad.

Program NAP and not DOZE. DOZE is present only on earlier CPUs
and the bit is reserved on the MPC7441 & MPC7451. NAP will do
bus snooping to keep caches coherent.

Program the PIR with the cpuid. This may not be necessary...

Retire the 'i_reclen' field from the in-memory i-node.  Previously,
during a DELETE lookup operation, lookup would cache the length of the
directory entry to be deleted in 'i_reclen'.  Later, the actual VOP to
remove the directory entry (ufs_remove, ufs_rename, etc.) would call
ufs_dirremove() which extended the length of the previous directory
entry to "remove" the deleted entry.

However, we always read the entire block containing the directory
entry when doing the removal, so we always have the directory entry to
be deleted in-memory when doing the update to the directory block.
Also, we already have to figure out where the directory entry that is
being removed is in the block so that we can pass the component name
to the dirhash code to update the dirhash.  So, instead of passing
'i_reclen' from ufs_lookup() to the ufs_dirremove() routine, just read
the 'd_reclen' field directly out of the entry being removed when
updating the length of the previous entry in the block.

This avoids a cosmetic issue of writing to 'i_reclen' while holding a
shared vnode lock.  It also slightly reduces the amount of side-band
data passed from ufs_lookup() to operations updating a directory via
the directory's i-node.

Add 'device acpi' to GENERIC on i386.  Most newer i386 machines require it,
so the benefit of having acpi.ko as a standalone module is outweighed by
the complications of drivers compiled into the kernel not including ACPI
attachments by default.

Implement zero-copy bpf(4) buffer or "zbuf" support for libpcap.  A slightly
different version has been committed upstream in the libpcap vendor branch.
This will allow people to experiment with zero-copy bpf(4) without requiring
external patches.

Note to enable this functionality:

    sysctl net.bpf.zerocopy_enable=1

By default, libpcap will use the legacy buffering method unless this sysctl
variable is set to 1.

For the details about zero-copy bpf(4) implementation see svn change r177548.

Remove the suser(9) interface from the kernel. It has been replaced from
years by the priv_check(9) interface and just very few places are left.
Note that compatibility stub with older FreeBSD version
(all above the 8 limit though) are left in order to reduce diffs against
old versions. It is responsibility of the maintainers for any module, if
they think it is the case, to axe out such cases.

This patch breaks KPI so __FreeBSD_version will be bumped into a later
commit.

This patch needs to be credited 50-50 with rwatson@ as he found time to
explain me how the priv_check() works in detail and to review patches.
