Richard W.M. Jones 61d4891ef4 mllib: Split ‘Common_utils’ into ‘Std_utils’ + ‘Common_utils’.
The new module ‘Std_utils’ contains only functions which are pure
OCaml and depend only on the OCaml stdlib.  Therefore these functions
may be used by the generator.

The new module is moved to ‘common/mlstdutils’.

This also removes the "<stdlib>" hack, and the code which copied the
library around.

Also ‘Guestfs_config’, ‘Libdir’ and ‘StringMap’ modules are moved
since these are essentially the same.

The bulk of this change is just updating files which use
‘open Common_utils’ to add ‘open Std_utils’ where necessary.
