sometimes, we want to do some initialize work in guest when guest startup,
but currently, qemu-agent doesn't support that. so here we add an init

libvirt can do some work for guest.

add 'aer' property to let user able to decide whether expose
the aer capability. by default we should disable aer feature,
because it needs configuration restrictions.

ses which I can
find, and begin make patches for tilegx, next.
Welcome any ideas, suggestions and completions (e.g. for test cases). If
no additional reply, I shall send patches for tilegx within 4 days.
Thanks.

For vfio pcie device, we could expose the extended capability on
PCIE bus. in order to avoid config space broken, we introduce
a copy config for parsing extended caps. and rebuild the pcie

the function is used to get affected devices by bus reset.
so here extract it, and can used for aer soon.

pcie_aer_init was used to emulate an aer capability for pcie device,
but for vfio device, the aer config space size is mutable and is not
always equal to PCI_ERR_SIZEOF(0x48). it depends on where the TLP Prefix
register required, so here we add a size argument.

It also needs "tcg_gen_movi_i64(vdst, 0);" or will generate assertion
`ts->val_type == TEMP_VAL_REG' in debug mode.
And I shall try to send patch within one day (sorry for a little late).
