  Modified files:
    lib/libc/stdlib      malloc.c 
  Log:
  Change the semantics of brk_max to dynamically deal with data segment
  bounds. [1]
  
  Modify logic for utilizing the data segment, such that it is possible to
  create huge allocations there.
  
  Shrink the data segment when deallocating a chunk, if it is at the end of
  the data segment.
  
  Rename chunk_size to csize in huge_malloc(), in order to avoid masking a
  static variable of the same name. [1]
