PATCH [base vtpm and libxl patches 1/6] Upgrade vtpmd from 0.5.1 to 0.7.4
Update vtpmd from 0.5.1 to 0.7.4. Also adds checks for cmake
and gmp to the configure script if vtpm is enabled.
Signed off by Matthew Fioravante matthew.fioravante@jhuapl.edu
---
Changed since previous:
* added checks for libgmp and gmp.h if vtpm is enabled
* small documentation updates
