Remove old version. Getting ready for new libpcap 1.5
Remove commas from clauses in a comma-separated list.
Fix typo.
Describe all NFLOG TLV types and define structures for some of them.
Check caplen in the NFLOG TLV loop.
Have nflog_tlv_t include only the TLV header.
Byte-swap the T and L in TLVs as necessary when reading an NFLOG file.
Don't support D-Bus sniffing on OS X.
Add post-1.5.2 bug fixes.
Tag some changes with a bug identifier.
Add items for 1.5.1 and 1.5.2.
Formatting tweak.
Count *ring buffer blocks*, not *packets* to be filtered in userland.
Add a PACKET_COUNT_IS_UNLIMITED() to test for a packet count <= 0.
Use HAVE_TPACKET3 rather than TPACKET_V3 to test for TPACKET_V3 support.
Fix builds on systems without TPACKET_V3.
tweak manpages formatting
Fix pcap_loop() with a count of 0 and TPACKET_V3.
Discourage the use of a zero timeout.
We can't use TPACKET_V3 in immediate mode, so fall back on TPACKET_V2.

+.SH NAME
+pcap_file \- get the standard I/O stream for a savefile being read
+.SH SYNOPSIS
+.nf
+.ft B
+#include <pcap/pcap.h>
+.ft
+.LP
+.ft B
+FILE *pcap_file(pcap_t *p);
+.ft
+.fi
+.SH DESCRIPTION
+.B pcap_file()
+returns the standard I/O stream of the ``savefile,'' if a ``savefile''
+was opened with
+.BR pcap_open_offline() ,
+or NULL, if a network device was opened with
+.B pcap_create()
+and
+.BR pcap_activate() ,
+or with
+.BR pcap_open_live() .
+.PP
+Note that the Packet Capture library is usually built with large file
+support, so the standard I/O stream of the ``savefile'' might refer to
+a file larger than 2 gigabytes; applications that use
+.B pcap_file()
+should, if possible, use calls that support large files on the return
+value of
+.B pcap_file()
+or the value returned by
+.B fileno()
+when passed the return value of
+.BR pcap_file() .
