tpm2-tss: new package

OSS implementation of the TCG TPM2 Software Stack (TSS2). This stack
consists of the following layers from top to bottom:

* System API (SAPI) as described in the system level API and TPM command
  transmission interface specification. This API is a 1-to-1 mapping of
  the TPM2 commands documented in Part 3 of the TPM2 specification.
  Additionally there are asynchronous versions of each command. These
  asynchronous variants may be useful for integration into event-driven
  programming environments. Both the synchronous and asynchronous API
  are exposed through a single library: libsapi.

* TPM Command Transmission Interface (TCTI) that is described in the
  same specification. This API provides a standard interface to transmit
  / receive TPM command / response buffers. It is expected that any
  number of libraries implementing the TCTI API will be implemented as a
  way to abstract various platform specific IPC mechanisms. Currently
  this repository provides two TCTI implementations: libtcti-device and
  libtcti-socket. The prior should be used for direct access to the TPM
  through the Linux kernel driver. The later implements the protocol
  exposed by the Microsoft software TPM2 simulator.
