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.

chardev-frontends need to explictly check, increase and decrement the

This fixes things like:
qemu-kvm -chardev stdio,id=foo -device isa-serial,chardev=foo \
-mon chardev=foo
Working, where they should fail. Most of the changes here are due to

This patch allows to specify multiple directories where qemu should look
for data files. To implement that the behavior of the -L switch is
slightly different now: Instead of replacing the data directory the
path specified will be appended to the data directory list. So when
specifiying -L multiple times all directories specified will be checked,
in the order they are specified on the command line, instead of just the
last one.
Additionally the default paths are always appended to the directory
data list. This allows to specify a incomplete directory (such as the
seabios out/ directory) via -L. Anything not found there will be loaded
from the default paths, so you don't have to create a symlink farm for
all the rom blobs.
For trouble-shooting a tracepoint has been added, logging which blob
has been loaded from which location.

This patch adds support for cancelling an executing TPM command.
In Linux for example a user can cancel a command through the TPM's
sysfs 'cancel' entry using
echo "1" > /sysfs/class/misc/tpm0/device/cancel
This patch propagates the cancellation of a command inside a VM
to the host TPM's sysfs entry.
It also uses the possibility to cancel the command before QEMU VM
shutdown or reboot, which helps in preventing QEMU from hanging while
waiting for the completion of the command.
To relieve higher layers or users from having to determine the TPM's
cancel sysfs entry, the driver searches for the entry in well known
locations.

This patch adds support for TPM command line options.
The command line options supported here are
./qemu-... -tpmdev passthrough,path=<path to TPM device>,id=<id>
-device tpm-tis,tpmdev=<id>,id=<other id>
and
./qemu-... -tpmdev help
where the latter works similar to -soundhw help and shows a list of
available TPM backends (for example 'passthrough').
Using the type parameter, the backend is chosen, i.e., 'passthrough' for the
passthrough driver. The interpretation of the other parameters along
with determining whether enough parameters were provided is pushed into
the backend driver, which needs to implement the interface function
'create' and return a TPMDriverOpts structure if the VM can be started or
'NULL' if not enough or bad parameters were provided.
Monitor support for 'info tpm' has been added. It for example prints the
following:
(qemu) info tpm
TPM devices:
tpm0: model=tpm-tis
\ tpm0: type=passthrough,path=/dev/tpm0,cancel-path=/sys/devices/pnp0/00:09/cancel
