Improve region I/O sub-routines by re-writing most of low level part

Browse Source 
of AML interpreter.
 - Delete and cleanup a lot of almost duplicated code in kernel/userland.
 - Add new common functions for kernel/userland code.
      aml_adjust_readvalue(), aml_adjust_updatevalue(),
      aml_region_handle_alloc(), aml_region_handle_free() and
      aml_region_io().
 - Add primitive functions for both versions of kernel/userland in order to
   have shared code as much as possible.
      aml_region_read_simple(), aml_region_write_simple(),
      aml_region_prompt_read(), aml_region_prompt_write() and
      aml_region_prompt_update_value().
 - Consider update rule and access type in field flags. Also add a lot of
   definitions for the flags.
 - Fix bugs on bit manipulation for read/write operations.
 - Fix bugs on IndexField I/O part.  Also add workaround for temporary
   object corruption during StoreOp interpretation.
