Revert r330897:
This was intended to be a non-functional change. It wasn't. The commit
message was thus wrong. In addition it broke arm, and merged crypto
related code.
Revert with prejudice.
This revert skips files touched in r316370 since that commit was since
MFCed. This revert also skips files that require $FreeBSD$ property
changes.
Thank you to those who helped me get out of this mess including but not
limited to gonzo, kevans, rgrimes.

Partial merge of the SPDX changes
These changes are incomplete but are making it difficult
to determine what other changes can/should be merged.
No objections from: pfg

Copy head@r302406 to stable/11 as part of the 11.0-RELEASE cycle.
Prune svn:mergeinfo from the new branch, as nothing has been merged
here.
Additional commits post-branch will follow.

If a conditional jump instruction has the same jt and jf, do not perform
the test and jump unconditionally.

- Add more aggressive BPF JIT optimization. This is in more favor of i386
while the previous commit was more amd64-centric.
- Use calloc(3) instead of malloc(3)/memset(3) in user land[1].

Add an experimental and rudimentary JIT optimizer to reduce unncessary
overhead from short BPF filter programs such as "get the first 96 bytes".

- Allocate scratch memory on stack instead of pre-allocating it with
the filter as we do from bpf_filter()[1].
- Revert experimental use of contigmalloc(9)/contigfree(9). It has no
performance benefit over malloc(9)/free(9)[2].

- Make BPF JIT compiler working again in userland. We are limiting size of
generated native binary to page size for now.
- Update copyright date and fix some style nits.

Add experimental BPF Just-In-Time compiler for amd64 and i386.
Use the following kernel configuration option to enable:
options BPF_JITTER
If you want to use bpf_filter() instead (e. g., debugging), do:
sysctl net.bpf.jitter.enable=0
to turn it off.
Currently BIOCSETWF and bpf_mtap2() are unsupported, and bpf_mtap() is
partially supported because 1) no need, 2) avoid expensive m_copydata(9).
Obtained from: WinPcap 3.1 (for i386)
