Determine if spec file patches are actually applied and striplevel

There's a little more to patch handling in spec files than "patchX:"
fields - the patch actually has to be applied in the %prep section as
well, though this can take one of several forms (%autosetup / %autopatch
which apply all patches, individual %patchX directives, or even direct
application (rare). There's also the matter of the striplevel (-p option
to the patch command). Add fields to record whether or not a patch is
applied and the striplevel.
