This series of patches adds support for vTPM state encryption by passing
the read-end of a pipe's file descriptor to 'swtpm_setup' and 'swtpm'
where they can read a passphrase from and derive a key from that passphrase.

The TPM's domain XML looks to enable state encryption looks like this:

     <tpm model='tpm-tis'>
       <backend type='emulator' version='1.2'>
         <encryption secret='2c9ceaba-c6ef-4f38-86fd-6e3adb2df5cd'/>
       </backend>
     </tpm>

Hi Daniel,


  I adapted this now to what you suggested. Can you have a look ?
