2.2.0

Added

• New configuration option `--disable-defaultflags/ added. This is
  for use for packaging for targets that do not support the default
  compilation / linking flags.

Changed

• Use private dependencies properly in pkg-config metadata for TCTI.
• Refactor daemon main module to enable better handling of error
  conditions and enable more thorough unit testing.
• Updated dependencies to ensure compatibility with pkg-config fixes
  in tpm2-tss.

Fixed

• Bug causing TCTI to block when used by libtss2-sys built with partial
  reads enabled.
• Removed unnecessary libs / flags for pthreads in the TCTI pkg-config.
• Output from configure script now accurately describes the state of the
  flags that govern the integration tests.
