Beginnings of a DECT dissector. This is a copy of the svn
repository at dedected.org with the following modifications:

- Change from plugin to normal dissector
- Change comments from // to /* */
- Change German comments to English
- #if-0-out unused variables
- Reorder functions to avoid forward declarations and use the normal
  Wireshark conventions
- Fix the scrt table (as by email from Andreas)
- Fix Mask for hf_dect_A_Tail_Qt_0_Cn from 0x2F -> 0x3F (as by email
  from Matthias)
- Initialize some variables because GCC isn't aware of the reduced
  value space in a switch statement that switches on (var & 7).
- Declare some function parameters as _U_
- Add GPLv2 and later header (as by emails from Andreas and Matthias).

TODO (roughly in that order)
  - Don't use structs to access the elements in the datastream.
  - Use tvb_..._item wherever possible
  - Add references to documentation (ETSI EN 300 175 parts 1-8)
    including the section.
  - Make things stateful
  - Once the capture format has stabilized, get rid of the Ethernet
    hack and use a proper capture type.

+Description:
+============
+DECT pcap files can be obtained by using tools coming with the linux
+kernel driver for the Dosch-and-Amand COM-ON-AIR cards. The driver is
+called com-on-air_cs.
+
+Wireshark itself cannot directy record from the DECT HW, as the driver
+currently lacks a virtual network interface.
+
+There is ongoing work to change this (see this work by Patrick McHardy):
+git clone git://git.kernel.org/pub/scm/linux/kernel/git/kaber/dect-2.6.git
+git clone git://git.kernel.org/pub/scm/linux/kernel/git/kaber/libnl-dect.git
+git clone git://git.kernel.org/pub/scm/libs/netlink/libnl.git
+Also needed are a proper linktype value assigned by the libpcap team and
+the proper patches for libpcap to support this (the value used in the
+patch below is not officially assigned!):
+git://git.kernel.org/pub/scm/linux/kernel/git/kaber/libpcap-dect.git
