This series cleans up two kinds of error_printf() misuse:

* Errors and warnings should be reported with error_report() and
  warn_report().

* Help output should be go to stdout, not stderr.

This is obviously for 4.1.  If nobody objects, I'll take the whole
series through my tree.

Based-on: <20190131164614.19209-1-cfergeau@redhat.com>

v3:
* PATCH 03: Replaced by new PATCH 14 [Paolo]
* PATCH 10: Trivial conflict with "[PATCH v7 0/2] log: Make glib
  logging go through QEMU" resolved.

v2:
* PATCH 02: Commit message tweaked, indentation fixed [Eric]
* PATCH 10: Indentation fixed [Marcel]
* PATCH 11: Use-after-free fixed [Patchew]
* PATCH 12: test-util-sockets.c updated along with stubs/monitor.c
* PATCH 14: Commit message typo [Eric]

Markus Armbruster (15):
  qemu-img: Use error_vreport() in error_exit()
  block/ssh: Do not report read/write/flush errors to the user
  loader-fit: Wean off error_printf()
  mips/boston: Report errors with error_report(), not error_printf()
  pci: Report fatal errors with error_report(), not error_printf()
  hpet: Report warnings with warn_report(), not error_printf()
  vfio: Report warnings with warn_report(), not error_printf()
  s390x/kvm: Report warnings with warn_report(), not error_printf()
  vl: Make -machine $TYPE,help and -accel help print to stdout
  monitor error: Make printf()-like functions return a value
  qemu-print: New qemu_printf(), qemu_vprintf() etc.
  blockdev: Make -drive format=help print to stdout
  char: Make -chardev help print to stdout
  char-pty: Print "char device redirected" message to stdout
  monitor: Simplify how -device/device_add print help
