Ensure that the device_add error code path deletes device objects.
Failure to do so not only leaks the objects but can also keep other
objects (like drive or netdev) alive due to qdev properties holding

Previous versions of QEMU produced a duplicate ID error because
drive_add leaked the options.

Existing qmp() callers do not expect a response object.  In order to

Rename qmp() to qmp_discard_response().  Later patches will introduce a

Stop/cont commands are broken with -icount due to a deadlock.  The
real problem is that the computation of timers_state.cpu_ticks_offset
makes no sense with -icount enabled: we set it to an icount clock value
in cpu_disable_ticks, and subtract a TSC (or similar, whatever
cpu_get_real_ticks happens to return) value in cpu_enable_ticks.

The fix is simple.  timers_state.cpu_ticks_offset is only used
together with cpu_get_real_ticks, so we can use cpu_get_real_ticks
in cpu_disable_ticks.  There is no need to update cpu_ticks_prev
at the time cpu_disable_ticks is called; instead, we can do it
the next time cpu_get_ticks is called.

The change to cpu_disable_ticks is the important part of the patch.
The rest modifies the code to always check timers_state.cpu_ticks_prev,
even when the ticks are not advancing (i.e. the VM is stopped).  It also
makes a similar change to cpu_get_clock_locked, so that the code remains
similar for cpu_get_ticks and cpu_get_clock_locked.

We currently just update the HMP NIC info when the last bit of macaddr
is written. This assumes that guest driver will write all the macaddr
from bit 0 to bit 5 when it changes the macaddr, this is the current
behavior of linux driver (e1000/rtl8139cp), but we can't do this
assumption.

The macaddr that is used for rx-filter will be updated when every bit
is changed. This patch updates the e1000/rtl8139 nic to update HMP NIC
info when every bit is changed. It will be same as virtio-net.

The documentation of how overlapping memory regions behave and how
the priority system works was rather brief, and confusion about
priorities seems to be quite common for developers trying to understand
how the memory region system works, so expand and clarify it.
This includes a worked example with overlaps, documentation of the
behaviour when an overlapped container has "holes", and mention
that it's valid for a region to have both MMIO callbacks and
subregions (and how this interacts with priorities when it does).
