There is a bug in the vtpm_manager that has to do with hashing and
saving the NVM memory files (vtpm_dm_%d.data). The file is not
truncated when it is written and this results in the hash becoming
invalid because of the extra bits at the end of the file.
This patch adds O_TRUNC to the flags when opening the file.

The attached patch uses the TPM to encrypt the symmetric keys and other
global secrets before saving them to disk.

The VTPM manager and VTPMs fully support both 32 and 64 bit OSes. The
tpm_emulator (provided for debugging on TPM-less machines) does not
support 64-bit kernels by default though. See the README for details on
how to use it on 64-bit kernels.
