[e6f27aa56f] Initial import of libtommath-1.0

This commit brings in libtommath-1.0, as of tag v1.0 of the upstream repository
at https://github.com/libtom/libtommath.

Only the top-level directory has been imported: the demo, etc, logs, mtest,
pics, pre_gen, and tombc directories have been removed from our repo.

The stubs tables have been regenerated to accomodate for the new function:
mp_expt_d_ex(mp_int *a, mp_digit b, mp_int *c, int fast);
See https://github.com/libtom/libtommath/commit/e9b1837 for details.

Only the unix build system has been modified for now. Windows and Mac OSX will
come later.
