Speed Profile Calculation Function

Our motion function needs several speed parameters from users.
Some parameters are conflict in speed profile. For example, if
users input a very fast speed profile and a very short distance to
motion function, the speed profile is not exist for these parame-
ters. At this situation, motion library will keep the acceleration and
deceleration rate. It tries to lower the maximum speed from users
automatically to reform a speed profile feasible. The following dia-
gram shows this concept.

Our motion library has a series of functions to know the actual
speed profile of the command from users.
