Merge remote-tracking branch 'mjt/trivial-patches' into staging

# By Stefan Weil (5) and others
# Via Michael Tokarev
* mjt/trivial-patches:
  configure: Add signed*signed check to [u]int128_t test
  Makefile: pass include directives to dtc via CPPFLAGS, not CFLAGS
  qapi: lack of two commas in dict
  sd: pass bool parameter for sd_init
  qemu-char: use bool in qemu_chr_open_socket and simplify code a bit
  vnc: use booleans for vnc_connect, vnc_listen_read and vnc_display_add_client
  block/nand: Formatting sweep
  qxl: Fix QXLRam initialisation.
  acl: acl_add can't insert before last list element, fix
  configure: Fix "ERROR: ERROR: " for missing/incompatible DTC
  audio: Replace static functions in header file by macros, remove GCC_ATTR
  libcacard: Fix cppcheck warning and remove unneeded code
  savevm: Fix potential memory leak
  kvm: Fix potential resource leak (missing fclose)
  qemu-img: Add missing GCC_FMT_ATTR
  qemu-options: trivial fix for -mon args help
  vl: reformat SDL ifdeffery a bit
