Log Message:
gomoku: turn spotstr.s_frame into a frame index

Most calculations are done on the frame index, not the pointer. This
avoids dealing with ptrdiff_t conversion to int.

Changing the type of s_frame changes the size of struct spotstr, it is
now 56 bytes on LP64 and 48 bytes on ILP32, neither of which is a power
of two. Remove the dummy padding since compilers no longer generate
division instructions for divisions by small integer constants, so that
optimization is no longer necessary.

No functional change.
