    libpayload: Add wrappers for malloc which check its return value.
    
    The xmalloc wrapper checks whether the malloc succeeded, and if not stops
    execution and prints a message. xmalloc always returns a valid pointer. The
    xzalloc wrapper does the same thing, but also zeroes the memory before
    returning it.

    libpayload: malloc: Fix xmalloc() for zero byte allocations
    
    The C standard considers it legal to return a NULL pointer for zero
    length memory allocations, and our malloc implementation does in fact
    make use of that. xmalloc() and xzmalloc() should therefore not consider
    this case a failure.
    
    Also fixed a minor formatting issue.
