Message

Developers often run QEMU without installing. The bundle mechanism
allows to look up files which should be present in installation even in
such a situation.

v2: Rebased to the latest QEMU.

This is supposed to work already -- it is why find_datadir() looks
at a path based on qemu_get_exec_dir() as well as at the
CONFIG_QEMU_DATADIR.

If you want to replace that mechanism, you need to explain:
 * under what circumstances it isn't working correctly
 * why we should replace it with a different design rather
   than attempting to fix its bugs
 * why the design you're proposing is the right way to do that

The cover letter is a good place to explain that sort of
thing, so people understand why the patchset is doing what
it is before they dive into the detail.

datadir is only for pc-bios and does not include icons and 
qemu-bridge-helper. find_bundle is a general mechanism which can be used 
for any files to be installed.
