a59bcd31c9 qemu-char: add_handlers: Don't re-send the be_open event on unregister 
Resending the be_open event only is useful when a frontend is registering, not

190832289f qemu-char: Automatically do fe_open / fe_close on qemu_chr_add_handlers 
Most frontends can't really determine if the guest actually has the frontend
side open. So lets automatically generate fe_open / fe_close as soon as a
frontend becomes ready (as signalled by calling qemu_chr_add_handlers) /
becomes non ready (as signalled by setting all handlers to NULL).

And allow frontends which can actually determine if the guest is listening to
opt-out of this.

2c8a59422c char: Fix return type of qemu_chr_fe_add_watch() 
qemu_chr_fe_add_watch() can return negative errors, therefore it must
not have an unsigned return type. For consistency with other
qemu_chr_fe_* functions, this uses a standard C int instead of glib
types.

In situations where qemu_chr_fe_add_watch() is falsely assumed to have
succeeded, the serial ports would go into a state where it never becomes
ready for transmitting more data; this is fixed by this patch.

4549a8b7ee Add a TPM Passthrough backend driver implementation 
This patch is based of off version 9 of Stefan Berger's patch series
  "QEMU Trusted Platform Module (TPM) integration"
and adds a new backend driver for it.

This patch adds a passthrough backend driver for passing commands sent to the
emulated TPM device directly to a TPM device opened on the host machine.
Thus it is possible to use a hardware TPM device in a system running on QEMU,
providing the ability to access a TPM in a special state (e.g. after a Trusted
Boot).

This functionality is being used in the acTvSM Trusted Virtualization Platform
which is available on [1].

Usage example:
  qemu-system-x86_64 -tpmdev passthrough,id=tpm0,path=/dev/tpm0 \
                     -device tpm-tis,tpmdev=tpm0 \
                     -cdrom test.iso -boot d

Some notes about the host TPM:
The TPM needs to be enabled and activated. If that's not the case one
has to go through the BIOS/UEFI and enable and activate that TPM for TPM
commands to work as expected.
It may be necessary to boot the kernel using tpm_tis.force=1 in the boot
command line or 'modprobe tpm_tis force=1' in case of using it as a module.

Andreas Niederl, Stefan Berger

                                               "device":"/dev/ttyS0"} } } }

becomes

    { "execute" : "chardev-add",
      "arguments" : { "id" : "ser0",
                      "backend" : { "type" : "serial",
                                    "data" : { "device":"/dev/ttyS0"} } } }

Bonus: nicer error messages.  "unknown chardev port (1)" becomes
"character device backend type 'parallel' not supported".

Commit 6daf194d and be62a2eb got rid of a bunch, but they keep coming
