History
Jason Chen CJ 88758dfe57 add copy_from_gva/copy_to_gva functions 
there are data transfer between guest virtual space(GVA) & hv(HVA), for
example, guest rip fetching during instruction decoding.

GVA is address continuous, but its GPA could be only 4K page address
continuous, this patch adds copy_from_gva & copy_to_gva functions by
doing page walking of GVA to avoid address breaking during accessing GVA.

v2:
- modify API interface based on new gva2gpa function, err_code added
- combine similar code with inline function _copy_gpa
- change API name from vcopy_from/to_vm to copy_from/to_gva
