[PATCH] add new fdi directives

[Danny Kukawka]

Hi,

this patch introduce new fdi-file <match> directives for strings. The new are:
 - string_outof
 - prefix_outof
 - contains_outof

They all work like the normal directives (string, prefix, contains), but only 
on string properties and match against a ';'-separated list (any other ideas 
for a char as separator?) as in this examples:

  <match key="system.hardware.product" string_outof="foo;bar">
  - matches if "system.hardware.product" is 'foo' or 'bar'

  <match key="system.hardware.product" prefix_outof="foo;bar">
  - matches if "system.hardware.product" starts with 'foo' or 'bar'

  <match key="system.hardware.product" contains_outof="foo;bar">
  - matches if "system.hardware.product" contains the (sub-)string 
    'foo' or 'bar'

This new match directives allow us to reduce the size (and number of 
duplicated rules) of many fdi files in hal and hal-info. See as example a new 
version of fdi/information/10freedesktop/30-keymap-acer.fdi which I reduced 
from 28532 to 8123 bytes (which is ~ -72 %).

If this new directives are okay to commit I would also add a 'int_outof' to 
handle e.g. usb/pci ids e.g. for mp3 player.

Please review/comment.

Danny
