747b5dd95d Update to 1.45
v1.45

        o fixed bug where setting the snaplen smaller than the minimum
          necessary to read the full headres would cause garbage to be
          fed into the pattern matcher

        o fixed unreported bug in IPv6/TCP packet length calculation

        o relocated the privilege-dropping routine to be invoked right
          before entering the packet processing loop, to prevent
          interference with necessary permissions to read or write
          dumpfiles/etc.

        o fixed integer overflow with the snaplen that resulted from
          an implicit signed/unsigned conversion

        o minor change to compensate for some broken compiler
          optimizers

        o fixed double-free race condition during ngrep termination

        o reworked packet length calculation in the main processing
          loop, improving performance and readability

        o simplified regex build logic in configure and Makefile

        o updated Win32 version to use config.h for preprocessor
          definitions instead of the Visual Studio project files,
          making manual tweaking and config of ngrep for Win32
          consistent with *NIX and more obvious

        o changed third-party Makefiles to properly clean up after
          themselves

        o added support for radiotap (IEEE802_11_RADIO)

        o changed ``-s 0'' invocation to mimic the equivalent of tcpdump

25c1717a9b Upgrade to version 1.43
v1.43

        o healed the win32 code fork: ngrep now builds from the same
          source tree for all platforms including Windows

        o re-wrote the privilege revocation logic after problems were
          reported with the SPC version, and removed non-root
          drop_privs capability altogether

        o fix off-by-one bug which caused ngrep to exit 1 packet early
          when ``-A'' as invoked

        o Fixed problematic configtest for old broken-redhat-glibc UDP
          header

        o ngrep now sets a pcap filter "ip" by default, if one is not
          specified

        o header offset fix to 802.11 processing

        o support IGMP and Raw (unknown IP protocol) type packets

        o support for latest versions of libpcap (0.8.3) and winpcap
          (3.1 beta 4)

        o updated configure to autoconf 2.59, and config.guess and
          config.sub to latest versions

        o updated PCRE from 3.4 to 5.0

        o and various minor changes and updates to improve ngrep

e13ceabf4d swap net/bpf.h and pcap.h since it gives strange results when having the
net/libpcap installed.

ea0bdc3c86 GNU configure is setting up PCAP_RESTART to use yyrestart. yyrestart in the
pcap library requires a FILE * argument, ngrep is called it with none.
