size_t silc_mp_sizeinbase(SilcMPInt *mp, int base);
DESCRIPTION
Return the size of the integer in base `base'.
NOTES
For any other base but 2 this function usually returns only an
approximated size in the base. It is however guaranteed that the
the returned size is always at least the size of the integer or
larger.
For base 2 this returns the exact bit-size of the integer.
