so that IF kerberos succeeds in decrypting a blob it can print a nice
"[Decrypted using: keytab principal foo/bar@REALM]"
or
"[Decrypted using: key learnt from frame xx]"
This makes it much easier to keep track of what keys decrypt what blob
and is very useful for illustrating the sequence of keys that are exchanged and used in kerberos during the AS/TGS/AP exchanges.

make ethereal attempt to automatically detect wether header digest is used or not for iscsi sessions.
This makes ethereal decode the packets properly EVEN for perfectly normal sessions where
the discovery session is performed with no digest but the normal login session negotiates digest.
the detected headerdigest setting is tcp session wide and thus it
it does not work for such initiators (if such exist) that resuse the same socketpair between the discovery and normal login sessions.

most if not all platforms; the "bitwise and" operator in display filters

Many people have recently reported many problems with the nmake build
process. It seems that these problems come from using
epan/makefile.nmake to compile the DISSECTOR_SUPPORT_SOURCES which are
located in /trunk.
Nmake from MSVC6 puts the object code of the DISSECTOR_SUPPORT_SOURCES
in /epan although Nmake expects the object code in /trunk when it
checkes dependencies. Thus DISSECTOR_SUPPORT_OBJECTS are built every
time even when they are already there.
Nmake Version 1.5 (MSVC 2003 Toolkit) puts the object code of the
DISSECTOR_SUPPORT_SOURCES in /trunk instead.
This makes it impossible to use epan/makefile.nmake for compiling the
DISSECTOR_SUPPORT_SOURCES and to make it work for both versions of nmake.
We have to use /trunk/makefile.nmake for compiling the
DISSECTOR_SUPPORT_SOURCES to solve these issues.
It should also be possible to build ethereal without libethereal.dll again.
Once we have moved all DISSECTOR_SUPPORT_SOURCES into a subdirectory of
epan we can get rid of this patchwork in the nmake makefiles.

There is still a problem with MSVC builds as 3 objects get built twice (once
at the top level, and once in epan: xmlstub.obj, print.obj and ps.obj).
This fix allows to compile again with MSVC if debug symbols are NOT enabled
while building Ethereal. Do this by editing config.nmake and replacing
"LOCAL_LDFLAGS=/DEBUG" with "LOCAL_LDFLAGS=". In other words: Ethereal CANNOT
be built right now with debug symbols in the object code, for MSVC builds.
