- Added another function called __reset_max_mem_stats() which will reset the

counters for "maximum amount of memory used" and "maximum number of chunks
  allocated" to the current figures for these values.

- Fixed the alloca() declaration in <stdlib.h> so that software which keys
  off the fact whether or not the alloca preprocessor symbol is defined
  will do the right thing.

- Added an optional call-back function which can be called if alloca()
  is about to return NULL, which some software does not consider.
  Rather than letting such software drop into an illegal memory access
  or worse, that call-back function will be invoked instead, which can
  print an error message and eventually call abort().

calls to succeed in trying to reallocate the same chunk of memory due to
a race condition. Fixed.
- Added a new function __get_mem_stats() (the prototype is in <dos.h>) which
can be used to query the current and maximum memory usage, counting the
allocations performed through malloc(), free() and all other functions which
use them.
