#5 Remove strtok in 2.5.6

[Anthony Liguori]

Replaced all strtok calls in 2.5.6 kernel with strsep
including the minimal amount of changes to various
drivers to work with strsep.

Left strtok in the kernel in order to avoid breaking
patches and/or binary modules that are not part of main
branch of kernel. Perhaps a printk should be added to
strtok?? I know ld has the ability to display warnings
about depreciated function use so I wonder if something
like that could be done for strtok.
