[PATCH v2 0/8] additional "ima-measurement" support

[Mimi Zohar <zohar@linux.ibm.com>]

"evmctl ima_measurement" walks the IMA measurement list re-calculating
the TPM PCR banks.

- Support the original method of extending the TPM 2.0 banks with the
  padded SHA1 digest.
- Instead of reading the hardware or software TPM PCRs, support
  providing the TPM 1.2 PCRs as a file.
- Limit the number of messages being emitted while verifying the
  measurement list.
- Reading the TPM PCRs before walking the measurement list guarantees
  the measurement list contains all the records, maybe too many.
- Rename "--list" to "--verify-sig", and update the README. 

Changelog v2:
- limit number of messages
- read PCRs before walking the measurement list
- and other miscellaneous cleanup
