* remotes/bonzini/tags/for-upstream: (50 commits)
  exec.c: workaround regression caused by alignment change in d2f39ad
  char: remove explicit_be_open from CharDriverState
  char: use common error path in qmp_chardev_add
  char: replace avail_connections
  char: remove unused qemu_chr_fe_event
  char: use an enum for CHR_EVENT
  char: remove unused CHR_EVENT_FOCUS
  char: move fe_open in CharBackend
  char: remove explicit_fe_open, use a set_handlers argument
  char: rename chr_close/chr_free
  char: move front end handlers in CharBackend
  tests: start chardev unit tests
  char: make some qemu_chr_fe skip if no driver
  char: replace qemu_chr_claim/release with qemu_chr_fe_init/deinit
  vhost-user: only initialize queue 0 CharBackend
  char: fold qemu_chr_set_handlers in qemu_chr_fe_set_handlers
  char: use qemu_chr_fe* functions with CharBackend argument
  colo: claim in find_and_check_chardev
  char: rename some frontend functions
  char: remaining switch to CharBackend in frontend
  ...
