More details in metaparameter redefinition warning

Definitions which redefine metaparameters, such as the following,
generate a warning because metaparameters, unlike normal parameters,
are inherited by all resources contained in the definition:

define contact_info($alias = undef) {

...

}

To find and fix this problem in the manifests we need to know where
the parameter is defined or at least the name of the definition, which
is now part of the warning message.
