mps_arena_vm_growth(): new interface function; client specifies
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.

mpsicv.c, comm.gmk: use auto_header format half the time (rnd() & 1).

- if VMChunkCreate fails, fall back: re-try with a smaller request;
- tidy up code to choose chunk size, with a consistent, smaller
(10%) .vmchunk.overhead estimate;
- add diag.

b) fallback to smaller sizes if request fails.
*** WARNING ***
VMChunkCreate() has test-code that deliberately fails requests,
for testing this functionality.

StringEqual(s1, s2).

Handle diag->buf overflow (in fact was already handled; now tested;
