- add fix_warnings.patch: fixes a couple of build errors resulting from LTO
  linking and -Werror.
- add fix_pie_linking.patch: fixes an error in the build system that causes
  the tss2 binary to be linked without passed LDFLAGS (like -pie), which
  causes the binary not to be position independent.
- update to major version 5.0:
  - 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 surprises.
    * 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 interrogate 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 separate 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.
  - Dependency update
    * Update tpm2-tss dependency version to 3.0.1
    * Update tpm2-abrmd dependency version to 2.3.3
  - New tools and features
    * tpm2_zgen2phase: Add new tool to support command TPM2_CC_ZGen_2Phase.
    * tpm2_ecdhzgen: Add new tool to support command TPM2_CC_ECDH_ZGen.
