ui: Added some missing functionality:
* Added an option to copy input device IDs to the relevant menus.
* Added an item for setting the software lists files path (-hashpath) to
the folder setup menu.
* Allow pasting text from clipboard in most places that allow typing
(searching, entering filenames, entering barcodes).
* Changed the software selection menu heading to be a bit less
misleading.
* Made barcode menu less eager to rebuild itself unnecessarily, and
removed some confusing and apparently pointless code.
Exposed more Lua bindings:
* Added low-level palette objects.
* Added indexed bitmap types.
* Added a bitmap method for extracting pixels from a rectangular area as a
packed binary string.
* Changed screen device pixels method to return width and height in
addition to the pixels.
osd: Added some functionality and cleaned up a little:
* Added a function for copying text to the clipboard.
* Moved function for converting Windows error codes to standard error
conditions to winutil.cpp so it can be used from more places.
* Removed duplicate declaration of osd_get_clipboard_text and made the
function noexcept (including fixing implementations).
* Made macOS implementation of osd_get_clipboard_text skip the encoding
conversion if it finds UTF-8 text first.
* Changed the default -uimodekey setting so it doesn't lose the "not
shift" that stops the default from interfering with UI paste.
Various bug fixes:
* util/unicode.cpp: Fixed the version of utf8_from_uchar that returns
std::string blowing up on invalid codepoints.
* util/bitmap.h: Fixed wrapping constructors for indexed bitmaps taking
the wrong parameter type (nothing was using them before).
* util/bitmap.cpp: Fixed potential use-after-free issues with bitmap
palettes.
* emu/input.cpp, emu/inputdev.cpp: Log 1-based device numbers, matching
what's shown in the internal UI and used in tokens in CFG files.
* emu/emumem.cpp: Added the bank tag to a fatal error message where it
was missing.
docs: Reworked and expanded documentation on configuring stable
controller IDs.
For translators, the changes are quite minor:
* There's a menu item for copying a device ID to the clipboard, and
associated success/failure messages.
* There's the menu item for setting the software list file search path.
* One of the lines in the software selection menu heading has changes as
it could be interpreted as implying it showed a software list name.
* Got rid of the special-casing for the "mess" subtarget name.
* Got rid of the MESS-specific Windows resources, emuator info source
and man page.
* Added subtarget name to the internal name and original name in Windows
resources.
-ui: Put the system-specific items on the input settings menu together,
and fixed the crosshair visibility settings.
Added menus for controlling toggle inputs, and showing recognised input
devices and control state. Moved input menu options off main menu to a
submenu, as there are a lot of them now.
Moved menu heading drawing into base class, added headings to more
menus, and made headings more consistent with the menu items used to
reach them. Also made terminology more consistent.
Changed the default names for buttons and hat switches/D-pads to use
1-based numbering. DirectInput still returns 0-based button numbers for
some devices.
Removed local copy of MinGW xaudio2.h as it’s now included in the MSYS2
package. Also fixed building the DirectSound sound output module with
the SDL OSD on Windows - the Windows headers are sensitive to include
order.
Started adding documentation for menus, to hopefully help people find
menus they remember seeing but can't recall how to access.
For translators, this makes terminology more consistent. In particular:
* "Settings" is preferred over "configuration" in a number of places, as
the latter can be construed as referring specifically to settings
stored in .cfg files in the cfg_directory folder. Also, references to
saving machine configuration could be interpreted as relating to the
settings on the "Machine Configuration" menu.
* The controls on host input devices (e.g. keys, buttons, joystick axes)
are referred to as "controls", while emulated inputs are referred to
as "inputs".
* The menus for assigning host controls to emulated inputs are called
"input assignments" menus to distinguish them from other input
settings menus.
* Combinations of controls that can be assigned to emulated inputs are
referred to as "combinations" rather than "sequences".
* The potentially confusing term "ROM set" has been removed altogether.
Use "short name" to refer to a device or system's identifier.
* "System" is used in almost places to refer to a complete, runnable
system rather than "Machine".
* "Driver" is now only used to refer to source files where systems or
devices are defined - it is no longer used to refer to individual
systems.
* A few more menus have message context for the messages. This makes it
a bit easier to guess where the messages are used. It also means you
can use different translations in different places if necessary (e.g.
if the same English text should be translated differently as an item
in one menu and as a heading in another).
