bin/mksh : var.c
Log message:
save tons of realloc and free by…
• reusing already allocated variables (and allocating them the max() size
needed in the first place)
• remembering the size allocated and avoiding shrinking calls to realloc
(unless a configurable amount is wasted to keep RAM usage sensible) in
those places where we guess the allocated size already (or with a small
change)
• use an on-stack buffer for variable names up to 31 bytes
also saves a few afree calls where we know it can’t be nōn-nil
