Bug-fixes:

lib/tpm2_nv_util.h: The NV index size is dependent on different data sets read from the GetCapability structures because there is a dependency on the NV operation type: Define vs Read vs Write vs Extend. Fix a sane default in the case where GetCapability fails or fails to report the specific property/ data set. This is especially true because some properties are TPM implementation dependent.

5.0 - 2020-11-16

Non Backwards Compatible Changes

Default hash algorithm is now sha256. Prior versions claimed sha1, but were inconsistent in choice. Best practice is to specify the hash algorithm to avoid suprises.
tpm2_tools and tss2_tools are now a busybox style commandlet. Ie tpm2_getrandom becomes tpm2 getrandom. make install will install symlinks to the old tool names and the tpm2 commandlet will interogate argv[0] for the command to run. This will provide backwards compatibility if they are installed. If you wish to use the old names not installed system wide, set DESTDIR during install to a seperate path and set the proper directory on PATH.
tpm2_eventlog's output changed to be YAML compliant. The output before was intended to be YAML compliant but was never properly checked and tested.
umask set to 0117 for all tools.
tpm2_getekcertificate now outputs the INTC EK certificates in PEM format by default. In order to output the URL safe variant of base64 encoded output of the INTC EK certificate use the added option --raw.
