For use in error and diagnostic messages, pmEventFlagsStr returns a
`human readable' version of the value flags, assuming this to be the
er_flags field of a pmEventRecord or pmEventHighResRecord. The
pmEventFlagsStr_r function does the same, but stores the result in a
user-supplied buffer buf of length buflen, which should have room for
at least 64 bytes.
The string value result from pmEventFlagsStr is held in a single
static buffer, so the returned value is only valid until the next
call to pmEventFlagsStr.
