  Modified files:
    lib/libc/stdlib      malloc.c 
  Log:
  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.
