Import some bond function which could ensure the parameter range

I port from paparazzi' project "std.h"
Bond radio control input and MOTOR CCR(PWM9~12)
Fix a error, bond should always do "after" calculatoin
Store the value of Final_M1~M4 before bonding

Because I want to see the "real" value of the parameter.
Even if it is out of the range, we still need to see the
real value of it.
