The simulated time ratio feature introduced a host_set_timeratio()
call in sim_head.c, but the Windows host time implementation was
missing this symbol, causing a link error. Add a no-op stub since
the time ratio feature is not implemented on Windows.

dispatch_walltime() expects a delta in nanoseconds from now, but the
previous code subtracted CLOCK_REALTIME from a CLOCK_MONOTONIC absolute
timestamp, which have different epochs and produce a meaningless result.
Fix by subtracting the current CLOCK_MONOTONIC absolute time to get the
correct remaining duration.

Add CONFIG_SIM_WALLTIME_RATIO Kconfig option and --sim-rt-ratio=
command-line argument to control the ratio of simulated time to
real time in percent. 100 means real-time (default), 200 means
simulated time advances twice as fast, 50 means half speed.
The implementation applies the ratio in host_gettime(), host_sleepuntil()
and host_settimer() so both SIM_WALLTIME_SLEEP and SIM_WALLTIME_SIGNAL
modes are supported.
This is inspired by the --rt-ratio feature in Zephyr's native_sim board.
Tested on sim:nsh with the following sleep test:
$ echo -e "sleep 2\nexit" | time ./nuttx
real 0m2.0xxs
$ echo -e "sleep 2\nexit" | time ./nuttx --sim-rt-ratio=200
real 0m1.0xxs
$ echo -e "sleep 2\nexit" | time ./nuttx --sim-rt-ratio=50
real 0m4.0xxs

macOS does not provide full POSIX timer support for the host-side
simulator build, so references to timer_t and timer_create can fail when
building sim:fb on Apple hosts. Replace the POSIX timer path with a
Grand Central Dispatch timer on macOS while keeping the existing POSIX
implementation for other hosts.
The dispatch timer raises SIGALRM from its event handler so the host
side keeps the same timer-driven behavior expected by the simulator.
This preserves the existing timing model and fixes the macOS host build
failure for sim:fb.

macOS does not ship X11 headers and libraries in the default system
search paths, so sim:fb fails to build unless the XQuartz installation
prefix is detected explicitly. Probe /opt/X11 first and fall back to
/usr/X11 so the simulator can find the required X11 headers and libs on
common macOS setups.
This fixes the sim:fb build failure on macOS hosts that rely on XQuartz
for X11 development files.

debug.h is a NuttX-specific, non-POSIX header. Placing it in the
top-level include/ directory creates naming conflicts with external
projects that define their own debug.h.
This commit moves the canonical header to include/nuttx/debug.h,
following the NuttX convention for non-POSIX/non-standard headers,
and updates all in-tree references.
A backward-compatibility shim is left at include/debug.h that
emits a deprecation #warning and re-includes <nuttx/debug.h>,
allowing out-of-tree code to continue building while migrating.

The X11 event loop in the POSIX simulator was processing MotionNotify
(touch/mouse movement)and ButtonPress/ButtonRelease events unconditionally,
even when the touchscreen feature(CONFIG_SIM_TOUCHSCREEN) was disabled.
This could lead to unnecessary event processing, potential compiler warnings
about unusedfunctions (e.g., sim_buttonevent), or unintended behavior in simulator
builds withouttouchscreen support. The touchscreen-related event handling should
only be active whenthe corresponding configuration is enabled.
This fix wraps the MotionNotify and ButtonPress/ButtonRelease event handling
logicwith #ifdef CONFIG_SIM_TOUCHSCREEN guards to:
1. Ensure touchscreen/mouse event processing is only compiled when CONFIG_SIM_TOUCHSCREEN is enabled.
2. Eliminate unused code warnings in non-touchscreen simulator builds.
3. Align event loop behavior with the configured feature set, reducing unnecessary runtime overhead.
The change maintains full touchscreen functionality when the config is enabled, whilecleaning up the
code path for builds that don't require touchscreen support.

The X11 framebuffer implementation in the POSIX simulator was creating a window
and graphics context but failing to map (display) the window to thescreen with XMapWindow().
This omission meant the framebuffer window would be created in the X11server but remain hidden,
making it impossible to see any graphics outputfrom the simulator. The window existed in the X11
server's state but wasnot rendered to the screen.
This fix adds the missing XMapWindow(display, g_window) call aftercreating the graphics context, which:
1. Maps the created X11 window to the screen (makes it visible).
2. Ensures framebuffer output is rendered to the display as expected.
3. Maintains compatibility with existing X11 framebuffer logic.
The change restores basic visibility of the simulator's framebuffer window,
fixing a critical usability issue for graphics-related testing in the POSIX simulator.

The sim_bthcisock_interrupt() handler for Bluetooth HCI sockets in the simulatorwas using
an if statement to check for available data on the HCI socket. Thismeant that only a single
packet would be read and processed per interrupt trigger,even if multiple packets were waiting
in the socket buffer.
This led to incomplete data processing: unread packets would remain in the bufferuntil the next
interrupt tick, causing delayed handling of Bluetooth HCI events/commands,packet backlogs,
or missed data in high-throughput scenarios.
This fix replaces the if with a while loop to:
1. Continuously check for and read available data from the HCI socket until no more
packets are present in the buffer.
2. Ensure all pending HCI packets are processed in a single interrupt handler invocation.
3. Eliminate packet backlogs and reduce latency in Bluetooth HCI communication.
The change maintains the same core data reception logic (bthcisock_receive()) butensures it runs
for all available packets, improving the reliability and responsivenessof the simulator's Bluetooth HCI socket implementation.

The wdog callbacks are executed in the host's signal handler context, which has strict limitations on what operations can be safely performed. Specifically, signal handlers should not call non-async-signal-safe functions (e.g., sim_alsa use mutex_lock in wdog and cause deadlock).
