xfree86: Add option parsing for percent options.

In some cases, an option of "50%" would be preferable over fixed value
configuration - especially if the actual values are autoprobed.
Add a new set of functions to parse percent values from configurations.

The percent value parsing differs slightly - if the option is not to marked
as used (e.g. xf86CheckPercentOption()), no warning is emitted to the log
file if the value is not a percent value. This allows double-options (either
as % or as absolute number) without warnings.
