engine.c: remove some old "#if 1"s, add compilation switch MULTI_COLUMN_VLINE.

Unconditionally enabled, but useful for comparing the behavior of the 1-column
vline functions against the 2- or 4-column ones.

Classic: fix drawing tilesizy=512 walls, use non-pow2 routines with pskies.

The former is really only a workaround. Walls/vertical sprites/pskies with
ysize 512 (and presumably greater, but this was not tested) are rendered
with one shade higher at the borders (1 pixel vlines) because of a certain
assumption in the ASM (see comments there). With very dark shades, the
palookup[] buffer is accessed oob. We simply allocate 256 bytes more at the
end for each.

The latter is only for CLASSIC_NONPOW2_YSIZE_WALLS builds, which is not enabled
yet. It seems to matter only for the uncommon case where the such pskies repeat
in the height. A 1680x1050 window fully covered with such a sky is then rendered
at about 60/85 the FPS for me (mostly due to not using the 4 pixel vline
routines), so it may be leaning a bit too much on the side of correctness.

A compilation switch DEBUG_TILESIZY_512 is introduced in engine.c for
demonstration purposes.
