Support record updating with "*" as record type

[klauer]

Expected Behavior

Per Andy Johnson, record updating can work with:

record("original_rtyp", "record_name") { ... base_fields ... }
record("*", "record_name") { ... updated_fields ... }

Current Behavior

Not sure; probably will throw a warning that the record types differ.

This is pretty wild behavior in EPICS, I didn't know you could do this
