eudev: new package

eudev is a userspace device management daemon. It is a standalone
version, independent from systemd. It is a fork maintained by Gentoo.

Features:

 - No extra configuration options are available: Gudev is build if
   libglib2 is selected.
 - No dependency on hwdata as the package uses its own hardware
   database (as does systemd).

eudev 1.3 is in sync with systemd v207.

[Peter: add BR2_USE_MMU dependency]

+#!/bin/sh
+#
+# udev	This is a minimal non-LSB version of a UDEV startup script.  It
+#	was derived by stripping down the udev-058 LSB version for use
+#	with buildroot on embedded hardware using Linux 2.6.34+ kernels.
+#
+#	You may need to customize this for your system's resource limits
+#	(including startup time!) and administration.  For example, if
+#	your early userspace has a custom initramfs or initrd you might
+#	need /dev much earlier; or without hotpluggable busses (like USB,
+#	PCMCIA, MMC/SD, and so on) your /dev might be static after boot.
+#
+#	This script assumes your system boots right into the eventual root
+#	filesystem, and that init runs this udev script before any programs
+#	needing more device nodes than the bare-bones set -- /dev/console,
+#	/dev/zero, /dev/null -- that's needed to boot and run this script.
