Peter Maydell 68d8ef4ec5 TCG Plugins initial implementation 
- use --enable-plugins @ configure
   - low impact introspection (-plugin empty.so to measure overhead)
   - plugins cannot alter guest state
   - example plugins included in source tree (tests/plugins)
   - -d plugin to enable plugin output in logs
   - check-tcg runs extra tests when plugins enabled
   - documentation in docs/devel/plugins.rst
