HV:treewide:Cleanup the type for parameters of bitmap

Browse Source 
operations

For reducing sign conversion in hypervisor:
Update parameters of bitmap operations as unsigned type;
Update the input of related caller as unsigned type when the
caller's input parameter is const variable or the variable is
only used by bitmap operations.

V1-->V2:
        (1) Explicit casting for the first parameter
            of all bitmap operations;
        (2) Remove mask operation for explicit casting
            of all bitmap operations, since masking is
            useless. Otherwise, this trucation is dangerous.
V2-->V3:
        (1) Explicit casting for all bitmap operations parameter;
        (2) Masking bit offset with 6-bit;
        (3) Add few comments about bit offset.
V3-->V4:
        add '\' for some statement of bitmap macro
