Fix multiple printf format problems

All printf var-args style methods should be annotation with
their format. All format strings must be const strings.

* client/application.cpp, client/cmd_line_parser.cpp,
  client/hot_keys.cpp: Avoid non-const format
* client/client_net_socket.cpp: Fix broken format specifier
* client/red_peer.cpp: Fix missing format specifier
* client/platform.h: Add SPICE_GNUC_PRINTF annotation to term_printf
* client/utils.h: Add SPICE_GNUC_PRINTF annotation to string_printf
* server/glz_encoder_config.h, server/red_worker.c: Add
  SPICE_GNUC_PRINTF annotation to warning callbacks
