libpcap-1.5.2
From Paolo Abeni:
Clarify that LINKTYPE_WIRESHARK_UPPER_PDU uses LINKTYPE_ values.
Add a pcap/ipnet.h file with IPNET definitions; use the right AF_ values.
Put the public libpcap headers into a pcap subdirectory in both the source directory and the target include directory, and have include files at the top-level directory to include those headers, for backwards compatibility.
Declare pcap_get_adapter() on Win32.
packaging/pcap.spec is generated from packaging/pcap.spec.in; don't check in the generated version, and don't put it into the distribution.
Byte-swap the extra fields in the "version 1" USB monitor header.
