Summary

• Cleanup of leftovers of the Win32 UI and legacy Makefile:
  • Hardcode the Qt UI CMake option to ON on Windows;
  • Remove leftover header files, trim win.h to only contain manager protocol stuff;
  • Clean up the plat_ and ui_ internal API: functions no longer defined or used in any of the remaining UIs have been removed; non-multi-monitor-aware plat_resize() has been removed, with plat_resize_monitor() being renamed to plat_resize();
  • Overhaul plat_get_string() to take constants with human-readable names instead of Win32 string table IDs; ui_msgbox() and ui_msgbox_header() no longer accept said IDs either, the pointer returned by plat_get_string() must be passed explicitly.
• Translation cleanup:
  • Remove many unused strings;
  • The Windows font override is now hardcoded to specific languages that need such an override instead of being defined by the translation file; the original way only made sense in the context of the Win32 UI anyway;
  • Some strings in the translation files have been updated to no longer require search-and-replace to insert platform-dependent information or to fit the Qt UI;
  • Restore the pcap error messages talking about (wi)Npcap on Windows instead of libpcap;
  • The translation files now have headers indicating their source and target languages;
  • the English translation files have been purged from redundant localizations.
• Other cleanup:
  • Remove the unused and unfinished Qt SDL renderer;
  • Remove the unused and unmaintained pcap_if utility;
  • Don't accept no longer used disk bus type options in the config file.
