Add a parameter to sensors_get_detected_chips(), to optionally let the

Browse Source 
caller select which subset of chips it wants. This is slightly better
size-wise than letting all applications do the filtering by themselves.

This will change the way the command line parameters of "sensors" are
interpreted. Beforehand, the chips were always returned in the order
in which they were listed by the library. Also, each chip could be listed
only once. From now on, the chips will be listed in the order in which
they are passed on the command line, which I think makes more sense. A
side effect is that chips can be listed more than once, if that's what
the user asks for. Not very useful though.

This change makes it possible to make sensors_match_chip() internal
to the library. Filtering the list of chips returned by
sensors_get_detected_chips() was the last known external use for this
function.

This patch looks much bigger than it really is, but the largest part is
really only code reindentation.
