Optimize realloc() to reallocate in place if the old and new sizes are

close enough to each other that reallocation would allocate a new region
of the same size.  This improves the performance of repeated incremental
reallocations by up to three orders of magnitude. [1]

Fix arena_new() to properly constrain run size if a small chunk size was
specified during runtime configuration.
