Markus Armbruster f8b0953bd5 Simplify qemu_realloc()
No functional change.  Bonus: looks just like qemu_malloc() now.

Anthony Liguori 20ff6c8066 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.
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.

aliguori 322691a5c9 Fix qemu_realloc() (Kevin Wolf)
For qemu_realloc with size == 0 a result of NULL is perfectly fine

aliguori 8a1d02aba9 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
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.

balrog ac4b0d0c4f Add qemu_strndup: qemu_strdup with length limit.
Also optimise qemu_strdup by using memcpy - using pstrcpy is usually 
suboptimal.
