Introduce two new QEMUSizedBuffer APIs which will be used by COLO to buffer
VM state:
One is qsb_put_buffer(), which put the content of a given QEMUSizedBuffer
into QEMUFile, this is used to send buffered VM state to secondary.
Another is qsb_fill_buffer(), read 'size' bytes of data from the file
If failover is requested, after some cleanup work,
PVM or SVM will exit COLO mode, and resume to normal run.

We add helper function colo_supported() to indicate whether
colo is supported or not, with which we use to control whether or not
showing 'colo' string to users, they can use qmp command
'query-migrate-capabilities' or hmp command 'info migrate_capabilities'
to learn if colo is supported.
The 'colo_nicname' should be assigned with network name,
for exmple, 'eth2'. It will be parameter of 'colo_script',
'colo_script' should be assigned with an scirpt path.
We parse these parameter in tap.

In postcopy we need the loadvm_handlers to be used in a couple
of different instances of the loadvm loop/routine, and thus
it can't be local any more.

qemu_peek_buffer currently copies the data it reads into a buffer,
however a future patch wants access to the buffer without the copy,
hence rework to remove the copy to the layer above.

Does tt only block virtio-blk/scsi? Not all block types?
It's only necessary for dataplane enabled devices, which are virtio-blk and

What all callers of fdctrl_reset_fifo() really want to do is to start
the command phase, where writes to the data port initiate a new command.
The function doesn't only clear the FIFO, but also sets up the state so
that a new command can be received. Rename it to reflect this.
Signed-off-by:
The RQM bit in MSR should be set whenever the guest is supposed to
access the FIFO, and it should be cleared in all other cases. This is
important so the guest can't continue writing/reading the FIFO beyond
the length that it's suppossed to access (see CVE-2015-3456).
Commit e9077462 fixed the
The hotfix for CVE-2015-3456 fixed the security problem, but didn't
fully correct the behaviour of the emulated floppy controller. This
series fixes the bug that was the root cause for the problem, and does
some cleanup in the FIFO access functions to make the command processing
more obvious.
phys_page_set_level is writing zeroes to a struct that has just been
filled in by phys_map_node_alloc. Instead, tell phys_map_node_alloc
whether to fill in the page as a leaf or as a non-leaf.
memcpy is faster than struct assignment, which copies each bitfield
individually. Arguably a compiler
