Eiichi Tsukata 2d3deaef29 swtpm: Abstract NVRAM interface for pluggable state store 
Related GH issue: https://github.com/stefanberger/swtpm/issues/461

This patch adds an abstraction layer to NVRAM state store implementation
for pluggable storage backends. No functional changes are intended in
this change. The default state store backend ("dir backend") keeps
current behavior.

To make swtpm ready for pluggable store, this patch moves file related
operations to the seperate file (swtpm_nvstore_dir.c) and defined the
interface for plugins (nvram_backend_ops in swtpm_nvstore.h). The
interface can be used by each plugin which will be added later.

With the interface, each plugin can access its "backend_uri" which
points to the location of the backend storage, for example S3 bucket
URL or iSCSI URL, and decide how it stores TPM state data.

SWTPM - Software TPM Emulator
      David Safford safford@us.ibm.com
      Stefan Berger stefanb@us.ibm.com

The SWTPM package provides TPM emulators with different front-end interfaces
to libtpms. TPM emulators provide socket interfaces (TCP/IP and Unix) and
the Linux CUSE interface for the creation of multiple native /dev/vtpm* devices.

The SWTPM package also provides several tools for using the TPM emulator,
creating certificates for a TPM, and simulating the manufacturing of
a TPM by creating a TPM's EK and platform certificates etc. Please read 
the READMEs in the individual tool's directory under src/.

Please consult the Wiki for information about swtpm:
