reworked talloc() to in order to help track down invalid
memory access. Tridge, I don't think using 0xdeadbeef for size allocations of 0 is going to work. I ended up having to use NULL as much code that works on UNISTR checks to see if the buffer ptr is NULL. So valid code ends up with a seg fault. Rather than rewriting it all, I added a DEBUG_TALLOC #ifdef in talloc.h that sets a macro BAD_PTR. This is the value assigned to ptr for an allocation of 0 bytes. jerry (This used to be commit 233b9cffa2350552d9f775f791d5d5e0464a1ed4)
