MFC: Sync. BPF JIT compiler with HEAD.

- r182172:
Embed scratch memory in the filter structure.

- r182173:
Fix a typo in copyrights.

- r182220:
Move empty filter handling to MI source.

- r182376:
Initialize scratch memory for JIT-compiled filter when it is allocated.
Previously it may have contained unnecessary (even sensitive) data from
the previous allocation.
As a (good) side effect, scratch memory may be used to store the previous
filter state(s) safely because it is allocated and freed with filter itself.
However, use it carefully because bpf_filter(9) does not have this behavior.
