Eiichi Tsukata c0ccbb042d tests: Fix test_tpm2_save_load_state_da_timeout rare timer race 
When there is a delay between "Sending TPM2_NV_Write with wrong
password" and "timenow=$(date +%s)", the test can fail with "Error: Did
not get expected failure from TPM2_NV_Write() with good password.
Lockout should be enabled.". This can sometimes happen on slow or busy
systems.

To stabilize the test, this patch introduces precise recovery time
measurement ($timerecovery) and check good password works after that
time. As for lockout timeout, moves starting timer just before
TPM2_NV_Write and check good password fails before that time.

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/.
