Export Pcap functions needed to capture specifying an internal buffer size

[martinuy]

The goal of this task is to export more Pcap functions (so they are available from Python) in order to open a live capture in the same way than calling pcap_open_live function but being able to specify the internal buffer size. In a way, pcap_open_live is a wrap-up for many of these functions but it's not as flexible as manually calling each one.

The functions we have listed to achieve this goal are the following:

• pcap_create
• pcap_set_snaplen
• pcap_set_promisc
• pcap_set_timeout
• pcap_set_buffer_size
• pcap_activate

Please check that this functions are both available from Linux Pcap and WinPcap. If not, add pre-processor directives to avoid compilation or linking issues.

Presumably by "Linux Pcap" you mean "UN*X Pcap", as they're not Linux-specific.

And there will be more such functions in the future.
