Depending on the dpi settings, the debug overlay was almost unreadable.
I also took the liberty to refactor some redundant client size calls and to add some margin to the left of the debug text.
Rewritten the following global utility constants:
`umax` returns max number, restricted to unsigned.
`smax` returns max signed number, restricted to integrals.
`smin` returns min signed number, restricted to signed.
`amin` returns smin or zero, less restricted.
`amax` returns smax or umax, less restricted.
Fix operators == and <=> for synthesized rel-ops.
* Fix typo in lv2_obj::create.
* Always save ipc_key as 0 for non-shared object creations, regardless of thbe value set by creation attribute.
* Show IPC key of shared memory (sys_mmapper) memory objects in kernel explorer.
* Remove custom event queue's IPC management of favour of universal LV2 approach.
* Move ipc_manager to FXO.
* Fix ipc_manager internal storage memory leak: deallocate entry when IPC object destroyed.
* Rewrite lv2_obj::create to be simpler (remove many duplicated code).
* Always execute lv2_obj::create under both IPC and IDM mutexes at once (not in non-atomic single-steps). Fixing potential case where concurrency can cause IDM to contain 2 or more different objects with the same IPC key with SYS_SYNC_NOT_CARE (instead of the same object).
* Do not rely on smart ptr reference count to tell if the object exists. Use similar approach as event queues as it makes error checkings accurate.
* Optimize lv2_event_port by using std::shared_ptr for queue which wasn't allowed before.
Removes the ability to stop or restart emulation via keyboard shortcuts
while the game is running. Prevents loss of work that can happen due to
the current bindings conflicting with very-widely established shortcuts.
Ctrl+C and Ctrl+E will now be unbound, and Ctrl+R will now mean Resume.
Strings that mention these keybinds were adjusted accordingly.
We now pass a shared pointer to the icon items, so there is no need to trigger a full refresh of the list anymore.
Sadly this doesn't apply to the game grid.
