The proper way how to disable the water limit in the isc_mem context is
to call:
isc_mem_setwater(ctx, NULL, NULL, 0, 0);
this ensures that the old water callback is called with ISC_MEM_LOWATER
if the callback was called with ISC_MEM_HIWATER before.
Historically, there were some places where the limits were disabled by
calling:
isc_mem_setwater(ctx, water, water_arg, 0, 0);
which would also call the old callback, but it also causes the water_t
to be allocated and extra check to be executed because water callback is
not NULL.
This commits unifies the calls to disable water to the preferred form.
