The TPM subsystem does not have a full front-end/back-end separation.
The sole available backend, tpm_passthrough, depends on the data
structures of the sole available frontend, tpm_tis.
However, we can at least try to split the user interface (tpm.c) from the
implementation (hw/tpm). The patches makes tpm.c not include tpm_int.h,
which is shared between tpm_tis.c and tpm_passthrough.c; instead it
moves more stuff to tpm_backend.h.

After attaching the source, we have to remove the reference we hold
to it, because we do not hold anymore a pointer to the source.
If we do not do this, removing the source will not finalize it and
will not drop the "real" I/O watch source.
This showed up when backporting the new flow control patches to older
versions of QEMU that still used select. The whole select then failed
with EBADF (poll instead will reporting POLLNVAL on a single pollfd)
and QEMU froze.

In handling float64_muladd, if we end up doing a subtraction of the
product and c, and the 128 bit result of this subtraction happens to
have its most significant bit in bit 63, we weren't handling this
correctly when attempting to normalize to put the most significant
bit into bit 126. We would end up doing a right shift by a negative
number (undefined behaviour in C) so at best we would return an
incorrect result to the guest. MSB in bit 63 has to be handled as a
special case separately from MSB in 0..62 and MSB in 63..126. (MSB
in 127 is not possible.)

The existing bdrv_co_flush_to_disk implementation uses rbd_flush(),
which is sychronous and causes the main qemu thread to block until it
is complete. This results in unresponsiveness and extra latency for
the guest.
Fix this by using an asynchronous version of flush. This was added to
librbd with a special #define to indicate its presence, since it will
be backported to stable versions. Thus, there is no need to check the
version of librbd.
Implement this as bdrv_aio_flush, since it matches other aio functions
in the rbd block driver, and leave out bdrv_co_flush_to_disk when the
asynchronous version is available.

qemu-system-x86_64 -drive file=ssh://hostname/some/image
QEMU will ssh into 'hostname' and open '/some/image' which is made
available as a standard block device.
You can specify a username (ssh://user@host/...) and/or a port number
(ssh://host:port/...). You can also use an alternate syntax using
properties (file.user, file.host, file.port, file.path).
Current limitations:
- Authentication must be done without passwords or passphrases, using
ssh-agent. Other authentication methods are not supported.
- Uses a single connection, instead of concurrent AIO with multiple
SSH connections.
This is implemented using libssh2 on the client side. The server just
requires a regular ssh daemon with sftp-server support. Most ssh
daemons on Unix/Linux systems will work out of the box.

What is the highest addressable sector on an empty CD-ROM? Nothing is
addressable so produce an error.
This patch prevents a divide-by-zero in ide_set_sector() since
s->sectors and s->heads would be 0. Not to mention that a sector=-1
argument would be nonsense.
Note that WIN_READ_NATIVE_MAX can be triggered using hdparm -N 1024
/dev/cdrom. The LBA bit will be set to 1 though, so the only easy way
to go down the ide_set_sector() CHS code path which divides by zero is
to comment out the s->select & 0x40 case for testing.
