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; Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
