qemu_malloc() does not allow size=0 to be passed in and aborts on this behavior.

Unfortunately, there is good reason to believe that within qemu, there are a
number of, so far, undetected places that assume size=0 can be safely passed.
Since we do not want to abort unnecessarily in production builds, return
qemu_malloc(1) whenever the version file indicates that this is a production
build.

For qemu_realloc with size == 0 a result of NULL is perfectly fine

Memory allocation failures are a very rare condition on virtual-memory
hosts.  They are also very difficult to handle correctly (especially in a
hardware emulation context).  Because of this, it is better to gracefully
terminate emulation rather than executing untested or even unwritten recovery
code paths.

This patch changes the qemu memory allocation routines to terminate emulation
if an allocation failure is encountered.

Also optimise qemu_strdup by using memcpy - using pstrcpy is usually 
suboptimal.

qemu_strdup() doesn't copy a last character because of off by one error.
