I reworked this a bit:
- Moved the globals into a new Pcap::* namespace, and renamed them
slightly.
- Moved the definitions of the globals into pcap/const.bif.
- Also moved the existing 'snaplen' into Pcap::* and removed
SnapLen() from the PktSrc API (it's really a pcap thing).
- Likewise moved the existing functions precompile_pcap_filter,
install_pcap_filter, and pcap_error, into Pcap::*.
- Did some more refactoring for the pcap code.
* 'master' of https://github.com/knielander/bro:
