executor: OpenBSD network package injection
Squash of:
* Doc typo
* Ported some tun related functions.
* Copy vnet.txt from linux to openbsd.
* Simplified syz_emit_ethernet and stubbed out vnet.txt.
* Undo clang-format header sorting: headers are order sensitive.
* Uniquify tap devices by pid.
* clang-format off for includes
* Happier clang-format.
* Partially revert "Uniquify tap devices by pid."
Just rely on procid magic instead of getting it from a flag.

There's also a nice feature: when syzkaller generates a C reproducer, it generates code to compute checksums in runtime as well. By using `syz_emit_ethernet` and `syz_extract_tcp_res` the following syzkaller program is able to establish a TCP connection over IPv4: |
