There were a few issues with the oss-fuzz integration from commit
8373f09854 ("build-sys: add oss-fuzz
support").
When building on OSS-Fuzz, the projects should use the provided CFLAGS
and CXXFLAGS and don't append any extra sanitization / fuzzing flags.
$LIB_FUZZING_ENGINE is defined to set the library to link to, and it
is a c++ library, so we should build fuzzer with c++...
Now --enable-fuzzer is only used for -fsanitize=fuzzer.
Add a tests/fuzz-main.c as fallback, to run the corpus on other builds.

Add support for --enable-test-coverage that sets additional CFLAGS
and LDFLAGS.
gcov creates files with suffixes .gcov, .gcno, and .gcda that we
need clean up in a few directories.

Add a simple test case to make sure that reading the PCRs
works as expected and that the state file is written
as expected. This state file (NVChip) is only written because
libtpms doesn't have any callbacks registered.

Make sure that the NVRAM offsets and structure sizes are the same
on all architectures so that we can fill up the NVRAM on one system
and migrate the state to another architecture and it will fit into
the NVRAM space there.
We leave some space for the first few data structures in the NVRAM to
grow. We do this by rounding up the NV_INDEX_RAM_DATA location to the
next kb boundary. This moves it from offset 4356 to 5120 on x86_64 and
from offset 4332 to 5120 on i386. This now leaves us with the same
amount of space for user dynamic NVRAM, which starts beyond offset 5120.
We also pad the OBJECT structure with 4 bytes so that it is the same
size on 32 and 64 bit architectures. This is a data structure that
is used in user dynamic NVRAM and should be the same size on all
architectures so that a full NVRAM always fits.
Also test the size of the NV_INDEX structure, which already has the
same size on all tested architectures (x86_64, i386, arm32, ppc64).

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>
