coredump: send the coredump in records if requested
When the coredump server raises COREDUMP_RECORDS send the coredump in
records. A record consists of a struct coredump_record_header and data.
A header and the bytes it describes go out in one iovec.
A hole is flushed through __dump_emit() like before. So zeroes still are
sent on the socket as actual data records. Making holes cheap is
COREDUMP_SPARSE's job.
