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
