Darwin does not have mremap. Use munmap+mmap instead.
That code is not in a hot path, number of nodes do not change very
often.

Simple usage improvement.
If only one process using spice is present allow to call
reds_stat not passing any pid.

Due to alignment problems the structure of statistics file is
different between 32 and 64 bit. This as on 32 bit uint64_t is
aligned to 4 bytes instead of 8 so sizeof(SpiceStat) can be either
20 (32 bit) or 24 (64 bit).
This cause reds_stat utility to be bit dependent.
Detect the correct SpiceStat size and use that information.

There's no reason for so hard optimisations so avoid
having to maintain multiple labels.

Some non-Linux platforms return a (caddr_t *) result for the return
value of mmap(), which is very unfortunate. Add a (void *) cast to
explicitly avoid the warning when compiling with -Werror.
For the IO vector related stuff, signed vs. unsigned comes into play so
adding a (void *) cast here is technically correct for all platforms.
