Peter Barker 6c377b2dcd AP_BattMonitor: tidy includes 2022-05-03 09:14:58 +10:00
Peter Barker 2c0f52a8b7 AP_BattMonitor: zero-terminate strings in caller rather than read_block 
It was noted that we did not increment the return value bufflen when
adding zero.  This is an ambiguity in the function declaration; if we
are told to add a zero should the return value be like strnlen (does not
include terminating null character) or read (includes all bytes used in
return buffer).

This PR makes it a non-issue by ensuring string null termination in the
caller and removing the append_zero parameter.
