The code is only used by x86 at this point. Merge common/hvm/save.c into x86 hvm/save.c. Move the headers and fix up inclusions. Remove the now empty common/hvm directory. Also fix some issues while moving: 1. removing trailing spaces; 2. fix multi-line comment; 3. make "i" in hvm_save unsigned int; 4. add some blank lines to separate sections of code; 5. change bool_t to bool.
