0b9f2fca53 Enable airpdcap debugging explicitly.
Enable airpdcap debugging with explicitly with AIRPDCAP_DEBUG instead
of _DEBUG. _DEBUG might be defined automatically by Visual C++ depending
on your build type and the extra output breaks the decryption tests.

9a73978ba5 Move airpdcap's print_debug_line() to airpdcap_debug.h
It saves a little on file pollution and the g_warning call isn't
bothered in the header file.

18b8f48bc1 Fix compilation when _DEBUG is defined.
CMake's Visual C++ generator creates projects that compile with the
Debug configuration by default, which defines _DEBUG. Fix DEBUG_DUMP's
declaration so that we compile in that case.

While we're here note that the "airpd" prefix isn't limited to AirPcap,
so we might want to change it accordingly.

cb3dd958af WPA/WPA2 decoding fixes and improvements
- start decoding when we have eapol1+2 packets
  Do not insist on a complete captured handshake, decode what we can.

- more robust way to detect eapol #2 packets
  At least Win 10 is violating the spec on rekey by setting the secure
  bit in #2. Unpatched version shows and handles #2 as #4, breaking
  decoding after rekey.

- fixed eapol rekey key handling
  Inital patch (see https://code.wireshark.org/review/8268)
  is adding redundant keys, since it scans all the time
  and not only once.

- ignore tailing garbage after eapol sections in frame
  See https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=9065#c8

Included testcase to test decode for incomplete handshakes and eapol2
packets with secure bit set on rekey.

a6415ece0a Rename a couple of to_str functions to have ep_ in the name. This makes it
obvious that the returned string is ephemeral, and opens up the original names
in the API for versions that take a wmem pool (and thus can work in any scope).

b5a8677250 Add WPA group key decryption from Brian Stormont, via bug 1420:
Although this patch successfully recognizes group keys and decrypts packets
properly using the group key, there is a limitation.  If an AP is using key
rotation, clicking on individual packets in a trace may not properly decrypt a
packet encrypted with a group key.  This is because the current structure used
in Wireshark only supports one active unicast and one active group key.  If a
new key has been seen, but you are looking at a packet encrypted with an older
key, it will not decrypt.  The summary lines, however, do show the packets
properly decrypted.

I've written up a much longer and more detailed explanation in a comment in the
code, along with a proposed idea for a solution, plus a clunky work-around in
the GUI when using the current code.

I also suspect there might still be a problem with decrypting TKIP groups keys
that are sent using WPA2 authentication.  In the most common operation, if you
are using WPA2, you'll also be using AES keys. It's not a common AP
configuration to use WPA2 with TKIP. In fact, most APs don't seem to support
it.  Since it is an uncommon setup, I haven't put aside the time to test this
patch against such an AP.   I do have access to an AP that supports this, so
when I have the time I'll test it and if needed, will submit another patch to
handle that odd-ball condition.

From me:

Remove the decrypt element of s_rijndael_ctx (which was unused, as indicated
in the comments).
Preserve the GPL licensing text in several files (which the patch shouldn't
have removed).
Remove changes that added whitespace.
Convert C++-style comments to C-style.
Update to include recent SVN changes (e.g. renaming variables named "index").
Remove extraneous printf's.
Define DEBUG_DUMP in airpdcap_debug.h.
Comment out some instances of DEBUG_DUMP.
Change malloc/free to g_malloc/g_free.
Use g_memdup instead of allocating and copying.
Use gint16 instead of INT16 in airpdcap_rijndael.c.
Add Brian to AUTHORS.

bd282b4114 Move the contents of airpdcap to epan/crypt. Try to fix the current
distcheck failure.  Move the nmake build targets for airpdcap from 
epan/dissectors to epan.  This will probably break the Windows build.
