Make it possible to set bits of the MSTA field for soft motors.
Add a new input link, called MINP, beside the existing DINP and RINP

MINP will read the new MSTA bits, but filter out the RA_DONE bit.
The RA_DONE bit will be taken from DINP (as before) and the RA_DONE bit
inside MINP will be ignored, preserving the RA_DONE coming from DINP

Note that the MINP needs to follow the bit-definition in MSTA.
It may update RA_PLUS_LS, RA_MINUS_LS.
RA_HOMED or other bits may be set as well, whatever the application needs.
MINP may be pointed to the output of a calc or transform record.

When implementing the MINP (MSTA input) it was overseen,
that MSTA is defined as 32 bit (where only 15 bits are used).
Correct this: use long instead of short.

Add the MINP field: It is "similar" to e.g. DINP
