* remotes/stsquad/tags/pull-tesing-and-misc-191219-1: (25 commits)
  tests/tcg: ensure we re-configure if configure.sh is updated
  trace: replace hand-crafted pattern_glob with g_pattern_match_simple
  linux-user: convert target_munmap debug to a tracepoint
  linux-user: log page table changes under -d page
  linux-user: add target_mmap_complete tracepoint
  linux-user: convert target_mmap debug to tracepoint
  linux-user: convert target_mprotect debug to tracepoint
  travis.yml: Remove the redundant clang-with-MAIN_SOFTMMU_TARGETS entry
  docker: gtester is no longer used
  Added tests for close and change of logfile.
  Add use of RCU for qemu_logfile.
  qemu_log_lock/unlock now preserves the qemu_logfile handle.
  Add a mutex to guarantee single writer to qemu_logfile handle.
  Cleaned up flow of code in qemu_set_log(), to simplify and clarify.
  Fix double free issue in qemu_set_log_filename().
  ci: build out-of-tree
  travis.yml: Enable builds on arm64, ppc64le and s390x
  tests/test-util-filemonitor: Skip test on non-x86 Travis containers
