(bug-fix:minor) GCC 4.7.2, when run with flags "-DNDEBUG -O3", throws an error if the global name qualification is used for arpa/inet.h functions (e.g. if "::ntohl" is used in place of "ntohl").
(change:minor) Added default value for some attributes, like promiscuous mde, filter netmask, read timeout and snapshot length. Also, it is now possible to set such attributes even if the capture handle has not been opened yet.
