Changes are:
1) M2P table and e820 table are changed to skip address space from
HVM_RAM_LIMIT_BELOW_4G to 4G.
2) shared io page location, when less than HVM_RAM_LIMIT_BELOW_4G
memory, it's the last page of RAM as today, or it's the last page of
HVM_RAM_LIMIT_BELOW_4G RAM.
3) in qemu-dm address space from HVM_RAM_LIMIT_BELOW_4G to 4G are
stuffed with mfns starting from 4G, so the 1:1 mapping can still works.
This is ugly, but another limit check patch as changeset 10757 will
prevent qemu-dm to access this range. This ugly stuffing will be
removed when the patch to remove 1:1 mapping from qemu-dm gets accepted
in the future.

qemu-dm runs daemonized and the default for -nographic is to redirect
the monitor and serial ports to stdio which causes qemu-dm to busy
read from stdin. Change the default for -nographic to redirect the
monitor and serial ports to /dev/null.

The first fragment is used to store the pending_idx of the leading
txreq if it doesn't fit in the head area. When it does fit into
the head we need to ensure that the first fragment contains a value
that is not equal to pending_idx as that's what we use to distinguish
between the two cases in a a number of places.
This patch sets the first fragment to ~0 which is not equal to any
valid pending_idx. Without this initialisation, we may double-free
a pending_idx if the first fragment happened to contain a value
equal to it (this usually happened with pending_idx 0).
