* coding.c (coding_set_destination): Check coding->src_pos only
when coding->src_object is a buffer (bug#9910).
* process.c (send_process): Set the member src_multibyte of coding
to 0 (bug#9911) when sending a unibyte text.
* callproc.c (Fcall_process): Set the member src_multibyte of
process_coding to 0 (bug#9912).
