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
