ab801874f8 attack the biggest stack users:
-mkfs_minix_main [busybox_unstripped]:                  4288
-mkfs_minix_main [busybox_unstripped]:                  4276
-grave [busybox_unstripped]:                            4260
(bzip2 users too - not listed)

price we pay in code size increase:

4c13922961 Introduce FEATURE_COPYBUF_KB.
People who want smaller stack at any cost may use it
to reduce cp's stack usage (FEATURE_COPYBUF_KB=1).
Desktop people may get faster copy of big files
(FEATURE_COPYBUF_KB=32 is ~30% faster than 4kb)
