This series of patches implements support for migrating the state of the
external 'swtpm' TPM emulator as well as that of the TIS interface. 

For testing of TPM 2 (migration) please use the following git repos and
branches:

libtpms: 
   - repo: https://github.com/stefanberger/libtpms
   - branch: tpm2-preview.rev146.v2

swtpm:
   - repo: https://github.com/stefanberger/swtpm
   - branch: tpm2-preview.rev146.v2

Regards,
  Stefan

Changes:
 v4->v5:
   - followed Marc-André's and Alan's comments where possible; some comments
     were not addressed and reasons posted to mailing list
   - converted debug statements to tracing
   - qemu_chr_fe_read_all does not return errno, so displaying expected versus
     received number of bytes rather than strerror(errno)
   - added test cases
   - added documentation for migration to docs/spec/tpm.txt

 v3->v4:
   - dropped the size limit enforcement on blobs received from the swtpm
   - the .post_load migration function requires errno's to be returned.
     -> some of the functions have been converted to return a better errno
