Expose the two new API calls TPMLIB_GetState() and TPMLIB_SetState().
Fix one parameter in the TPMLIB_GetState() call.

This patch adds APIs for getting and setting all types of state
blobs. We cache these blobs and allow them to be picked up when
the TPM starts. It will get any of these state blobs, if they
were set, before we go out and try to read the state blob from
a file.

The EK certificates need information about the TPM specification that was
implemented. The best place to get the information from seems the TPM itself.
So we implement a function TPMLIB_GetInfo() to allow to query for the TPM
specification information and possibly other information in the future.

Implement TPMLIB_ValidateState(), which is supposed to be used
for checking usability of state blobs before TPMLIB_MainInit()
is called or TPM_Startup has been sent to the TPM.
This function is useful to be called once TPM state blobs
have been migrated to a destination and we need to check
whether libtpms can use these state blobs and if not
we have a chance to fall back to the migration source host.

Also allow to get the minimum and maximum supported buffer size
with the TPMLIB_SetBufferSize() call.
Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com>
Implement TPMLIB_SetBufferSize() for setting the size of the I/O buffer
that the TPM may advertise. For TPM 1.2 the size remains fixed since the
TIS interface can handle the current 4096 bytes.
This function will be important for TPM 2 with a CRB interface that cannot
handle 4096 bytes.

Add API calls TPMLIB_SetDebugFD(), TPMLIB_SetDebugLevel(),
TPMLIB_SetDebugPrefix().
Convert the internal printing of debugging strings to
correspond to the log level. Print the prefix in front
of every line.

Remove unnecessary files in the repository and add boostrap.sh to create the
configure file and other files we are removing here. Users have to run
bootstrap.sh to have those files created in their build environment.
Update the INSTALL instructions.

This is the initial import of the libtpms library. The libtpms library
provides software emulation of a Trusted Platform Module (TPM). It is
intended to be used by applications when a hardware TPM is not adequate.
For example, a hypervisor can use libtpms to emulate an independent TPM
for each of it's virtual machine guests. The library provides a high-
level API for developers to integrate the emulated TPM support into
their application.
The code was originally written by Kenneth Goldman <kgoldman@us.ibm.com>
