1189.   [bug]           On some systems, malloc(0) returns NULL, which
                        could cause the caller to report an out of memory
                        error. [RT #2398]

594a685c8d Add ISC_MEM_DEBUGGING to set default compile time flags. 
Remember ISC_MEM_DEBUGRECORD state when isc_mem_create() is called as
it is dangerous to change this afterwards.

509ef0c871 Keep track of the number of times the system malloc() has 
failed, to help determine whether a server crash resulted
from a bug in the handling of an out-of-memory condition
or not.

65640f401a Removed the requirement for isc_mem_setwater() that when the callback function 
is not null then hi_water must exceed lo_water and both must be > 0.
Now requires hi_water >= lo_water, and they can both be 0.  Not allowing
them to be equal was just an unnecessary restriction, and letting them be 0
is useful for the case where the context has had non-zero values set, went
over hi_water and called the callback, and then wanted to remove limits
(perhaps because of a reconfiguration).  This allows the callback to
be signaled as ISC_MEM_LOWATER on the next isc_mem_put(), which the caller
might need to terminate any outstanding action that was triggered by
the hi_water.
