linux-zigbee: new package

linux-zigbee is a mix of utility tools that implements a 802.15.4 stack
along with a usefull library for any program that would need to use this
stack.

Note that the name is mislead, for licensing reason, this does *NOT*
implement the ZigBee protocol.

[Thomas:
 - add dependency on threads, propagated from libnl
 - improve the Config.in description by borrowing more text from the
   upstream website
 - fix the prompt of sub-options to be more consistent, and add help
   texts where appropriate
 - fix indentation of the BR2_PACKAGE_LINUX_ZIGBEE_TESTS option help
   text
 - add missing dependencies on host-pkgconf, host-flex and host-bison
 - add missing SoB line in the patch disabling test-serial. Maxime is
   a well-known contributor, so I assumed we had his SoB.
 - fix indentation of <pkg>_CONF_OPT.
 - remove <pkg>_INSTALL_STAGING = YES since the package does not
   install any library, and the two headers it installs are available
   through the toolchain kernel headers.
 - add comment to explain <pkg>_AUTORECONF = YES.]

+	  IEEE 802.15.4 is a standard for communication in small
+	  low-rate wireless personal area networks (WPAN). While
+	  802.15.4 is a MAC- and PHY- layer standard only, several
+	  common protocols commonly sit on top of it such as ZigBee,
+	  MiWi, and 6LoWPAN. The goal of this project is to create an
+	  implementation of 802.15.4 and several of the protocols
+	  which run on top of it (primarily 6LoWPAN) for Linux.
+
+	  It's worth noting that the name linux-zigbee is somewhat of
+	  a misnomer. While this project was originally started to
+	  create a ZigBee implementation for Linux, licensing
+	  restrictions put in place by the ZigBee Alliance make it
+	  impossible for an implementation of ZigBee to ever become
+	  part of the Linux kernel. Once this licensing issue was
+	  discovered, this project's primary focus shifted to IEEE
+	  802.15.4 and 6LoWPAN. Other higher-layer standards may be
+	  added at a future time.
+
+	  The 802.15.4 stack contains kernel components, which are
+	  part of the mainline Linux kernel, and userspace components,
+	  available in this package.

+This folders only contains python tests scripts which would force us to
+enable a dependency to host-python which seems kind of silly since
