Refine protocol decoding for: DNS: Use ND_TCHECK_LEN() instead of a custom bounds check. IPv6: Add a missing comma and remove a colon in the output. TCP: Note if the Urgent Pointer is non-zero while URG flag not set, if the verbose level is > 1 (option -vv and more). TCP: Note if the Acknowledgment Number is non-zero while ACK flag not set, if the verbose level is > 1 (option -vv and more). TCP: Fix Reset segment processing.

Print "invalid option -- z" when it is. Add the -g option, causing IPv4 output in verbose mode to be on one line. Other: Avoid race condition when receiving signal during shutdown. Always show the interface name in error messages when the interface can't be opened. Clean up the message shown if a -i flag is specified with an interface index that's too large.

Building and testing: Makefile.in: Use a local libpcap in the releasecheck target.

CMake: check whether check_c_source_runs() works, treat the build as a cross-compile if it doesn't work.
