      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
