    Support for TPM command line options · d1a0cf73

    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
