There are times when psError is called but there's no error return code

[rhl@…]

E.g. in psList.c, listSetIterator() calls psError, but is a void function so the error will get lost

We either need to change return type to bool or remove psError from the
following functions. I mark functions (1) to suggest we have them return bool,
or (2) to suggest we remove psError.

psTraceReset (2)
psLogSetFormat (2)
psListSetIterator (1)
psMetadataSetIterator (1)
psMetadataItemPrint (1)

Changed return type of psTraceReset, psLogSetFormat, psMetadataSetIterator,
psMetadataItemPrint to return type bool, so that errors won't be lost.
psListSetIterator has gone.
