* Less string copies
* Some general cleanups
* Add extra param to runloop_message_queue_push so we can pass size_t
of the message
* Consistent conventions for local variable usage for certain things
Adapt the sanitized pointer handling, discussed at #17196:
Wayland driver specific changes:
- make sure pointer position is always within [-0x7fff,0x7fff]
by using the confined wrapper
- enable lightgun to report -0x8000 if pointer is really offscreen
- remove extra "inside" checks
- report same pointer/lightgun coordinates for all ports
- simplify pointer and lightgun handling
Other changes:
- unify "offscreen" condition through input_driver.c
- slight tuning of pointer conversion in video_driver.c
- update libretro.h with explanation and pointer offscreen value
- small fixes on remote retropad test screen
New environment set call to enable a bit more sensible handling of
absolute pointing devices (pointer and lightgun). With the
confinement enabled, pointing devices will not return neither
-0x8000 nor (0,0), which was anyway dependent on the input driver,
instead they will stay at the extreme edge.
* Silence GCC 14 warning [-Warray-bounds=]
GCC reports a couple of warnings like this example:
libretro-common/cdrom/cdrom.c:395:14: warning: array subscript 6 is outside array bounds of 'unsigned char[6]' [-Warray-bounds=]
395 | cmd[6] = cmd[3];
| ~~~~~~~^~~~~~~~
libretro-common/cdrom/cdrom.c: In function 'cdrom_unlock':
libretro-common/cdrom/cdrom.c:1268:18: note: at offset 6 into object 'cdb' of size 6
1268 | unsigned char cdb[] = {0x1E, 0, 0, 0, 0x2, 0};
The static analysis heuristic doesn't consider the fact that the writes to cmd[6] and later only happen under the condition that `if (cmd[0] == 0xBE || cmd[0] == 0xB9)` and that in all of those cases the array passed is wide enough. So this is a false positive.
Nevertheless, there seems to be an easy way to silence the warning without disabling it: just require all arrays passed to be at least 9 bytes long and explicitly set the size of those arrays that have been shorter to 9.
* Work around the requirement of C89
I used a C99 construct, but this is easy to work around
with a run-time check.
* Restore the check for non-null cmd
It was obsoleted in a previous version, but is needed back now.
