Removing the NT_STATUS_HAVE_NO_MEMORY_AND_FREE macro

[Kamen Mazdrashki]

Hi list,

Perhaps I am missing something, but why we need this change to remove
NT_STATUS_HAVE_NO_MEMORY_AND_FREE? I understand there is
coding rule not to return from a macro, but in this case, this macro makes
the code easier to read.

Take for instance: libgpo/gpo_util.c:gpo_copy() function.
It is supposed to be just a simple copy-object implementation and using
NT_STATUS_HAVE_NO_MEMORY_AND_FREE it look straightforward
imho. But, now it is going to be bloated with 'if's all the way and this
will
literary double the length of it (which will make it hard to notice if you
have
missed to copy a struct field).

Just my 2c.

Cheers,
Kamen
