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.

Extend the previous support of a fixed buffer size to work
with a minimum of 3k and a maximum of 4k.

Also allow to get the minimum and maximum supported buffer size
with the TPMLIB_SetBufferSize() call.

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.

When checking for missing symbols we need to add -lc to the libraries
passed to gcc otherwise we always see lots of missing symbols even if
there aren't any.

LibreSSL on OpenBSD seems to not support the new API of OpenSSL 1.1.
So create a new #define OPENSSL_OLD_API that is set if the old API
is to be used.

Introduce an internal interface that allows us to reach TPM functionality
from the libary's API layer. This prepares the code for the addition
of a new API function that lets us choose which TPM to use, TPM 1.2 or
TPM2. Currently only TPM 1.2 functionality is available.

Disable the volatile storage debug for a debug build since this
causes the volatile state file to be written and this changes
the behavior upon a restart of the TPM. This may cause the TPM to
not work correctly then.
