Subject: [PATCH] Fix a build  error with Xorg master
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Use xf86ReturnOptValBool() in get_bool_option() instead of
options[option_index].value.bool to fix a compiler error with
current Xorg xserver master branch.

Also use xf86GetOptValInteger() in get_int_option() and
xf86GetOptValString() in get_str_option() for consistency.

The change causes a slight performance drop during option parsing
because the passed-in index_value is no longer used as an index
into the options array.

Instead, it's used as a token now for the standard option getter
functions which works since the index_value to the get_*_option()
functions are identical to the value of options[n].token in the
passed-in OptionInfoRec array.

Also rename "int option_index" to "int token" for clarity in all
three functions.
