netgraph: Remove the rethook parameter from NG_NODE_FOREACH_HOOK.

This parameter was set to the hook that terminated the iteration
early. However, none of the remaining callers used this argument and
it was always set to an otherwise-unused variable.

net: clean up empty lines in .c and .h files

IFC @230489 (pending review).

IFC @ r227804

Pull in the virtio drivers from head.

Mark MALLOC_DEFINEs static that have no corresponding MALLOC_DECLAREs.

This means that their use is restricted to a single C file.

integrate from head@185615

Retire the MALLOC and FREE macros. They are an abomination unto style(9).

Make sure BPF program is not bigger than set maximum (net.bpf.maxinsns).

Prepare hooks direct pointers on setup to avoid heavy ng_findhook() calls
during operarion.

Avoid data copying when it is possible.
bpf_filter() is able to work directly on mbuf chain.

Reduce stack usage by 256 bytes per call. It helps to avoid kernel
stack overflow in complicated traffic filtering setups.

There can be minor performance degradation for the MHLEN < len <= 256 case

Reduce stack usage by 256 bytes per call. It helps to avoid kernel
stack overflow in complicated traffic filtering setups.

There can be minor performance degradation for the MHLEN < len <= 256 case
due to additional buffer allocation, but it is a rare case.

Fix build without BPF_JITTER option.

Add BPF Just-In-Time compiler support for ng_bpf(4).

The sysctl is changed from net.bpf.jitter.enable to net.bpf_jitter.enable
and this controls both bpf(4) and ng_bpf(4) now.

/* -> /*- for license, minor formatting changes

Avoid calling bpf_filter() with len == 0, which causes a change in semantics
(it treats the buffer pointer as an mbuf pointer) and subsequent panic.

Fix GCC warnings caused by initializing a zero length array. In the process,
simply things a bit by getting rid of 'struct ng_parse_struct_info' which
was useless because it only contained one field.

Divorce the kernel binary ABI version number from the message
format version number. (userland programs should not need to be
recompiled when the netgraph kernel internal ABI is changed.

Also fix modules that don;t handle the fact that a caller may not supply
a return message pointer. (benign at the moment because the calling code
checks, but that will change)
