Scott Garman 7b079e1d08 Update meta-ide-support dependencies

Using poky-qemu with our new tap networking and/or unfs support
required too many additional build steps. This updates the
meta-ide-support dependencies so all features are built and
available to use.

Specifically, this adds psuedo-native, qemu-helper-native, and
unfs-server-native to the dependency chain for meta-ide-support.

This fixes [BUGID #392]

Also add poky-gen-tapdevs and remove runqemu-nfs from the
qemu-helper-native recipe, and update some qemu control script
error messages to suggest building meta-ide-support.

QEMU network interface configuration script. This utility needs to

be run as root, and will use the tunctl binary from a Poky sysroot.

Note: many Linux distros these days still use an older version of

tunctl which does not support the group permissions option, hence

the need to use Poky's version.

If you find yourself calling this script a lot, you can add the

the following to your /etc/sudoers file to be able to run this

command without entering your password each time:

ALL=NOPASSWD: /path/to/poky-qemu-ifup

ALL=NOPASSWD: /path/to/poky-qemu-ifdown

If you'd like to create a bank of tap devices at once, you should use

the poky-gen-tapdevs script instead. If tap devices are set up using

that script, the poky-qemu script will never end up calling this

script.
