PFW: Parameter adaptation (platform interface)

BZ: 15069

Adaptation nodes have been added to integer parameter types in the structural
description.
They all convert values between a platform value and the actual parameter
value.
When a conversion node affects the definition of an integer type parameter,
its interface type becomes "double" (instead of integer).
For now only linear adaptation type is supported.

Linear adaptation:
=================
Linear adaptation nodes consists of the following attributes:
- slope numerator (double, default = 1)
- slope denominator (double, defult = 1)
- offset (signed integer, default = 0)
Conversions from user (platform) values to blackboard are done the follwing
way:
blackboard_value = user_value * slope_numerator / slope_denominator + offset
