functions: added autodetection of format to cpulist_unpack

Now CPUs starting with 0x are taken as hexmask. As cpulist_unpack
is used as preprocessor of CPU list for other built-in functions
this also works with other functions (e.g. cpulist_invert).

Example:

[variables]
cpus = ${f:cpulist_invert:1-2,0x8}

On four CPU machines (CPUs 0-3) it expands to '0'.
