fdi files device syntax

[Richard Hughes]

On embedded devices running hald, we currently load and process all fdi
files placed in certain directories. For Stuff like 770 it make sense to
be able to specify "this fdi file never should be loaded" as stuff like
wireless mice make no sense for this type of device.

What I'm suggesting is the following:

<?xml version="1.0" encoding="ISO-8859-1"?> <!-- -*- SGML -*- --> 
<deviceinfo version="0.2">
  <device>
    <match key="info.int" int="666">
    fooo...

Adding an extra (optional) parameter to the device tag, so that we can
specify what type of device this fdi is target to.

<?xml version="1.0" encoding="ISO-8859-1"?> <!-- -*- SGML -*- --> 
<deviceinfo version="0.2">
  <device id="nokia770-version-a">
    <match key="info.int" int="666">
    fooo...

This saves deleting and adding custom fdi files for these devices, and
saves considerable time in the loading as we can have a runtime list of
"allowed devices".

Maybe there's a better way to do this, suggestions welcome.

Richard.
