d627a93193 Make mp_int constants `extern' for intermodule optimisation. 
The bodies of the functions returning `mp_int' constants may be copied
into C files generated for other Mercury modules.  The globals that
they reference must be visible outside of the `mp_int' module.

extras/mp_int/mp_int.m:
	As above.

e44737eb7a Add mp_int data type based on libtommath. 
This adds a new datatype mp_int for faster multi-precision integer
computations. It is based on calling the libtommath library throught the
FFI and works only in the C grades using the Boehm garbage collector.

extras/mp_int/mp_int.m:
        Add FFI binding to libtommath with API similar to integer.m

extras/mp_int/mp_int_test.m:
        Test basic functionality of mp_int.m.

extras/mp_int/README.txt:
        Description of how to download, compile and use the binding
        together with the library.

extras/README:
        Announce mp_int in extras folder.
