testing, gdbstub and plugin updates

  - enable more sbsa-ref tests in avocado
  - add swtpm to the package lists
  - reduce avocado noise in gitlab by limiting tests
  - make docker engine choice driven by configure and enable override
  - remove unneeded gcc suffix on some cross compilers
  - fix some NULL returns in gdbstub
  - improve locking in execlog plugin
  - introduce the GDBFeature structure
  - consistently set gdb_core_xml_file
  - use cleaner escaping for gdb xml
  - drop ancient gdb_has_xml() test
  - disable multi-instruction GUSA emulation when plugins enabled
  - fix some coverity issues in plugins
