Libpcap

- Add missing variable declaration missing from 0.0.6

- Workaround for problems when pcap_read() returns 0 due to the timeout
expiring.

- Change configuration to not use gcc v2 flags with gcc v1.

- Fixed a bug in pcap_next(); if pcap_dispatch() returns 0, pcap_next()
should also return 0. Thanks to Richard Stevens (rstevensnoao.edu).

- Fixed configure to test for snoop before dlpi to avoid problems under
IRIX 5. Thanks to J. Eric Townsend (jetabulafia.genmagic.com).

- Hack around deficiency in Ultrix's make.

- Fix two bugs related to the Solaris pre-5.3.2 bufmod bug; handle
savefiles that have more than snapshot bytes of data in them (so we
can read old savefiles) and avoid writing such files.

- Added checkioctl which is used with gcc to check that the
"fixincludes" script has been run.

- Fixed configure to test for snoop before dlpi to avoid problems under
IRIX 5. Thanks to J. Eric Townsend (jetabulafia.genmagic.com).

- Implement timeout in the dlpi pcap_open_live(). Thanks to Richard
Stevens.

- Determine pcap link type from dlpi media type. Resulted from report
by Mahesh Jethanandani (maheshnpix.com).

- Fixed bug in nit_setflags() in pcap-snit.c. The streams ioctl timeout
wasn't being initialized sometimes resulting in an "NIOCSFLAGS:
Invalid argument" error under OSF/1. Reported by Matt Day
(mdayartisoft.com) and Danny Mitzel (dmitzelwhitney.hitc.com).

- Turn on FDDI support by default.
