add "sample NUM" so you can ask to capture 1/NUM packets from a filter.

the use of the sample keyword matches similar config in other
products.

NUM can be a number between 2 and 1048576, and is used to divide
0x100000000 into a threshold that is then compared against a randomly
generated number produced by a load of BPF_RND.

having sampling as part of the grammar means you can write things
like "icmp or sample 128". this lets you capture all icmp traffic
and a sample of the rest of the traffic.

add support for handling loads from BPF_RND.

this adds "rnd" and "random" as keywords in the grammar, and handles
them as an arithmetic operator. the decoder recognises the load,
so tcpdump can print it as 'ld #random'. most of the handling is
copied from the "len"/"length" keywoard handling that generates and
decodes a load of the actual wire length of the packet.

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().

Remove the "volatile" attribute from bpf_error(). The "volatile"
attribute is an obsolete way of saying "noreturn". clang doesn't
recognize it and the function is already marked __dead so it is

get rid of arc network support. we have no users of it so this is dead
code. however, it is still cluttering up the kernel namespace a bit. it is
better gone.
