desired arena increment, and minimum arena increment.
arenavm.c: .chunk-create.fail: try a succession of _gradually_
reducing sizes (aiming to 'waste' at most 1/8th of the available
space, rather than the 1/2 that can be 'wasted' by halving each
time); stopping at specified minimum arena increment
(VMArenaStruct.extendMin) or 4K.

Hope to fix in time, but for now I need DIAG-out to work, so switch
to printf (yes, really, I know, sorry).
Also, only do DIAG-out in variety.di, to avoid damage to .ci.
So for now, remove DIAG_WRITEF and DIAG from arenavm and trace.
To test, add DIAG_PRINTF in trace.

amcss.c: make initial-size to mps_arena_create comically small,
to prompt VMChunkCreates and occasional MPS_RESERVE_BLOCK: 7's
