When we hotplug a nic to guest OS, we can see it

The reason of this bug is guest OS does not reset
nic, and we init eeprom(rtl8139) only when we reset
nic.
I think we should reset nic when we init it.

This patch fix the following two regressions:
1. we should use bitmap_set() and bitmap_clear() to replace vnc_set_bits().
2. The unit of bitmap_intersects()'third parameter is bit, not words.
But we pass the num of words to bitmap_intersects().

The new monitor command dump may take long time to finish. So we need run it
at the background.

Dump info contains: endian, class and architecture. The next
patch will use these information to create vmcore.

The command dump does not support to dump while vm is running. If the user
resume
the vm, we should auto cancel dumping and set the status to failed.

My first and the most important question is that: Is there necessary to
continue this work?
The attachment is the sample patch.
Thanks

Thank you very much!
. fix virt addr in the vmcore.
Wen Congyang (5):
Add API to create memory mapping list
Add API to check whether a physical address is I/O address
target-i386: implement cpu_get_memory_mapping()
Add API to get memory mapping
introduce a new monitor command 'dump' to dump guest's memory
The memory mapping list stores virtual address and physical address mapping.
The folloing patch will use this information to create PT_LOAD in the vmcore.

If rtl8139_can_receive() returns 1, it means that the nic can receive packet,
otherwise, it means the nic can not receive packet.
If !s-clock_enabled or !rtl8139_receiver_enabled(s), it means that the nic
can not receive packet. So the return value should be 0, not 1.

If !s-clock_enabled or !rtl8139_receiver_enabled(s), it means that
the nic will drop all packets from host. So qemu will keep getting
packets from host and wasting CPU on dropping packets. This seems
worse than packets that should be dropped but aren't.
