Add support for locking the storage file using fcntl(fd, F_SETLK, ...).
Since fcntl needs a file descriptor of the actual storage file, call
SWTPM_NVRAM_LinearFile_DoOpenURI() to open the file in case it has not
been opened, yet. In case of error close the file again but be careful
about the fact that it may not have been mmap'ed, yet.
Since now all backends have .lock and .unlock nvram_backend_ops, they can
be called without checking for a NULL pointer.
Extend an existing test case with a file-backend storage lock test.

Adapt save_load_state tests to include coverage of the "linear file"
backend mode. "tpm2" is save/load is tested with both a regular file and
a loop device to excercise the blockdev mmap code.

test_samples_create_tpmca needs to wait longer for the pid file content
to be there not just until the file is available.
test_tpm2_save_load_state_2 needs to dump the TPM log file on failure.
Failures occurred rarely because the previous instance of swtpm had
not shut down yet and released the lock file while the new instance
wanted to lock the lockfile. So we have to wait a bit until the
previous instance is gone.

tssgetcapability only retrieves a maximum of 64 handles by default.
However, there are 65 persisted keys. Pass -pc 80 to the command to
see all 65 Handles.

Add a test case that fills up the NVRAM area with as many persisted keys
as possible and then fills up the rest with an NVRAM index so that all
space is occupied. We have to be able to load this state again into the
NVRAM once the OBJECT's size increases due to RSA keys size increase,
which must have us increase the total size of NVRAM in libtpm's TPM profile.
The state in tests/data/tpm2state5/tpm2-00.permall was created using
libtpms 0.6.0, where only 2048 bit keys were supported and total NVRAM size
was 128kb. This state file should never be changed and always be loadable
into a current libtpms. In its USER NVRAM it holds 64 persisted 2048 bit
keys and an NVRAM index with 236 bytes. For this to stay the reference
NVRAM, we need to make sure that it fits exactly to the byte.
