Do not abort on qemu_malloc(0) in production builds

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....

Terminate emulation on memory allocation failure (Avi Kivity)

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...

Add qemu_strndup: qemu_strdup with length limit.

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