lib: Allow disabling partial read
This allows disabling partial reads. It adds a flag FLOWFRNOPART that
disables partial reads. Partial read is different from partial
delivery (FRCTFPARTIAL), which allows delivery of fragments of an
incomplete packet and thus potentially corrupted data. FLOWFRNOPART
will never deliver corrupted data (unless FRCTFPARTIAL is also set).
If FLOWFRNOPART is set and the buffer provided to flow_read is too
small for the SDU, that SDU will be discarded and -EMSGSIZE is
returned;
