Change some libpcap functions which use pointers as arguments and

returns to const pointers:

- the prefix argument to pcap_perror();
- the return value of pcap_strerror();
- the filter expression argument to pcap_compile() and pcap_compile_nopcap();
- the BPF filter program argument to bpf_image().

Matches changes made earlier in tcpdump.org's version of libpcap.
From Guy Harris, ok tb@, been through a bulk ports build.
