e48882fd0c [airpcap] Decrypt protected management frames (802.11w)
Enable decryption of Protected Management Frames by:
 - Authorizing decryption for robust management frame (i.e. management
   frame that may be encrypted): deauth, disassoc and action
   (Note: Assume all action frames are robust even if it is not the case)
 - Updating initialization of Additional Authentication Data (AAD)
   (don't filter-out subtype) and construct nonce (set mgmt flag) for
   management frames

2df54da6e2 Move a bunch of the crypt modules and pint.h into wsutil.
This means wsutil now links against libcrypt.

Protect a bunch of the crypt header files from multiple inclusion.

a3355a0949 Break the aes set ket/decrypt/encrypt out from airpdcap_raindoll into
its own crypt-aes.

change the integer types to glib style integers


this may/will be helpful if/when we implement our own version of 
kerberos 
aes decryption of dcerpc since the existing libraries can not (yet) 
handle when header signing is used.

we should implement our own decryption of this for cfx+aes just as we 
did for classic+arcfour

1d567d6e6b The 802.11 dissector calculates the header size, so pass that value to
the WEP/WPA decryption code instead of re-calculating it.  Fixes bug
1639.

Remove fcsPresent, radiotapPresent, and associated code from airpdcap.c
since they were always FALSE.  Glib-ize some data types.  Fixup white
space.

Update the release notes.

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.
