bitfield-c: use unsigned int instead of uint8_t
Use unsigned int instead of uint8_t upon destination and source array length. This is needed to handle gathered multi-frames message data which could be greater than 1 simple messages. Bug-AGL: SPEC-2988 Change-Id: I107bff383c2d0771dbc2a30770ec5c195b1c22ac Signed-off-by: Romain Forlot <romain.forlot@iot.bzh>
