    Update to detect Apple Clang 17+ and fix zlib issue.
    
    New Apple Clang 17 in Xcode 16.3+ causes build issues with bundled in zlib in binutils/gcc, so detect compiler version and use system zlib if necessary.

commit a3d0467bcb2659e44ce7cbeef6e900bb6f33cc62
Author: QuzarDC <qu...@co...>
Date:   Thu Jun 19 04:28:09 2025 -0400

    Map keyboard 'return' key to CR not LF.
    
    This was a regression in the new API from the start in 2012.
    By mapping LF to 'return' (0x28, the 'enter' key in the main
    block of keys) it meant that there was no way to send a return
    on keyboards that lacked a numpad.
    
    This change rolls us back to the mapping that had always been
    used in the older API. It seems that the issue had not been
    encountered or noted in large part because the old API's mapping
    had been maintained in code until #984 where I removed them for
    only differing in this one character code from the standard US
    keyboard. The old API is still what was backing conio/kosh and
    the change made them difficult to use.
    
    Of course it's still possible for the user to distinguish between
    the keys if they'd like, and these mappings only apply to using
    our built-in ASCII translation.

commit 3de8ac8f710ab4456c5abe5230c6615074fadb4f
Author: QuzarDC <qu...@co...>

    Apply noinline if we expect a function call for stack tracing.
    
    In the examples, ensure that the functions we are stack tracing
    are not inlined as it would defeat the purpose of the example.
    
    Inside the stack tracing functions and assert, there are assumptions
    made that we are going back by fixed numbers of frame pointers, so
    avoid inlining as that would the intended tracing.

    arch: Mark register access inlines as `always_inline`
    
    The behavior of these would break if the function call
    is not inlined, so ensure that they are always inlined.

    irq: Don't deref fp twice.
    
    In #600 there was a change to store `arch_fptr_ret_addr` as
    it was being tested as valid before being printed. Unfortunately
    this was done in a way that overwrote the current fp being worked
    on. So when it came time to pass it to `arch_fptr_next` another
    layer of deference was happening.

commit 50322ad313f8c46db7e1aa1391a153ae14f9f003
Author: Paul Cercueil <pa...@cr...>
Date:   Tue Jun 17 19:50:51 2025 +0200

    cdrom: Simplify vblank code
    
    Since nothing waited on the "cmd_done" semaphore anymore, the code
    signaling it as well as the semaphore itself can be dropped.
    
    The timeout code can also be dropped, as it was now handled by the
    cdrom_poll() function.
    
    The VBLANK interrupt handler now only has to check for errors when DMA
    is used.

commit 029c9098f68062e1c5c01a59d0ce3b20467249b3
Author: Paul Cercueil <pa...@cr...>
Date:   Tue Jun 17 15:17:24 2025 +0200

    cdrom: Use cdrom_poll() in cdrom_stream_request()
    
    Factorize code by using cdrom_poll() in cdrom_stream_request().
    
    Note how the calls to syscall_gdrom_dma_check() and
    syscall_gdrom_pio_check() are replaced by a call to
    cdrom_stream_progress() for further factorization.
    
    Also, the ERR_NO_ACTIVE value returned by the poll callback function is
    just here to signal the code calling cdrom_poll() that we got a
    "NO_ACTIVE" or "COMPLETED" response.

commit 380688e926ed40c3149b00df7d2feaa77be2cab3
Author: Paul Cercueil <pa...@cr...>
Date:   Tue Jun 17 14:41:51 2025 +0200

    cdrom: Use cdrom_poll() in cdrom_exec_cmd_timed()
    
    Factorize code by using cdrom_poll() in cdrom_exec_cmd_timed().
    
    This commit also fixes cdrom_exec_cmd_timed() being extremely slow;
    that's because after the command was sent to the GD drive, the response
    was only obtained after the next VBLANK, which meant having to wait for
    up to 16ms.
    
    Now, instead of waiting on the "cmd_done" semaphore signaled in the
    vblank interrupt, we poll for the command response until we obtain it.
    It will cause a slight CPU overhead but will be much faster.

commit 343c58a5c1172485f447928f5a0c6c4a9dd934d0
Author: Paul Cercueil <pa...@cr...>
Date:   Tue Jun 17 14:39:43 2025 +0200

    cdrom: Add function cdrom_poll(), use it in cdrom_req_cmd()
    
    The cdrom_poll() function will be used every time we need to poll the
    GD-ROM drive using syscalls.
    
    Use it in cdrom_req_cmd(), which changes from a 10-turn poll to a poll
    with a 10ms timeout, which should be plenty of time.

    Ensure that the thread's return can fit in the variable provided.
    
    `thd_join` is meant to take a `void **` by passing instead `bool *`
    you could get all sorts of bad stuff when the data overflows the bool.

commit af47450125b252204d3a9af3a76c837cca281ed1
Author: Falco Girgis <gyr...@gm...>
Date:   Tue Jun 17 13:45:38 2025 -0500

    Fixed maple crash when unknown device attached.
    
    Currently, the Maple driver crashes due to NULL pointer dereference in
    "maple_driver.c" on line 121. When the user manually disables certain
    Maple drivers via explicitly providing a custom KOS_INIT_FLAGS() list,
    and such a device is plugged into the controller, the "dev" pointer
    never gets allocated, since a driver for it is never found.
    
    1) Check to see if dev is NULL and error out early before dereferencing
       it.

    cdrom: Fixed confusion between sessions and areas.
    GD-ROM drive does not differentiate sessions at all. This TOC is always divided into two, for the low-density area and the high-density area, which is only on the GD-ROM disc.
    And in fact, this is one and the same TOC, it’s just that for non-requested area the tracks are erased (and first/last changed) in this common TOC, because the tracks numbering remains the same.
    There may be multiple sessions in one area, but there is no division between them.

commit 65b232b0fc206eb9dfd4705d460a9f29fc942839
Author: Falco Girgis <gyr...@gm...>
Date:   Sun Jun 8 07:44:25 2025 -0500

    Fixed race when getting/setting IRQ/TRAPA handlers
    
    When accessing an IRQ or TRAPA handler, it's possible that the handler
    could be swapped out from under you either fully or partially by another
    thread or IRQ.
    
    It's also possible an IRQ or TRAPA handler could be called from an IRQ
    WHILE its still being set by a user, so both the callback function and
    userdata pointers may not have both been set atomically before the IRQ,
    causing them to get out-of-sync.
    
    - Disabled IRQs around IRQ and TRAPA handler setter and getter
      accessors to ensure they accessed atomically.

commit e8a8adeb132df44c5e16b33b4540e0e418c774a4
Author: Falco Girgis <gyr...@gm...>
Date:   Sun Jun 8 07:58:30 2025 -0500

    Fixed main(..) function signature for examples.
    
    Several examples were giving warnings when compiled with LTO enabled,
    with GCC complaining about function signature mismatches between the
    "main()" prototype used within certain examples and the "mian(int argc,
    const char* argv[]) prototype that was predeclared within init.c.
    
    - Updated noncompliant examples to use proper main() signature.

    Correct `mutex_trylock` errno.
    
    According to POSIX spec EBUSY should be returned
    for trylock when the mutex couldn't be locked.
    EAGAIN is instead used if the max number of recursive
    locks for the mutex has been exceeded.

commit ca4a4104eaf7c9df5d2551f8ef7748e63a7a87d5
Author: Falco Girgis <gyr...@gm...>
Date:   Sun May 25 12:13:28 2025 -0500

    Cleaned up pvr_header.h. (#1051)
    
    * Cleaned up pvr_header.h.
    
    pvr_header.h was not matching the coding standards with the rest of the
    codebase. UnknownShadow also reported that our pvr_poly_hdr_t unionized
    structure lacked members for setting user clip area...
    
    1) Added typedefs to all structs and enumerations, because they're
       public and user-facing.
    2) Removed explicit names for padding in bitfields.
        a. They are not required.
        b. Even if they were, __ prefixing is reserved for internal
    toolchain and stdlib things and shouldn't be used.
    3) Made an alias for "to_pvr_txr_ptr()" which manages to be the only
       function, variable, or macro in the entire PVR API to not start with
    PVR.

commit a22cbb2314db9344debb8f86be9b4cdc226aa897
Author: QuzarDC <qu...@co...>
Date:   Thu May 22 15:01:40 2025 -0400

    Correct various doxygen warnings/issues.
    
    In a few files group end markers were missing, in a few special
    characters needed escaping, and others had incorrect names in
    the doc vs the actual code.

    Correct logical error in snd_stream double init protection.
    
    It was exactly backwards and never could have worked.

    Remove double-init of streams in multi-stream example.

commit c2327bd77f36f98ba02d7e17eb3b6dccdf6ba9c1

Date:   Thu May 22 21:50:32 2025 -0400

    Prevent double-init of snd_stream.
    
    Without this protection, there would be a memory
    leak caused by separation buffers being allocated
    multiple times.

commit f6f303f21187602e2783b64295c73d6650c8c17c
Author: Paul Cercueil <pa...@cr...>
Date:   Thu May 22 11:08:02 2025 +0200

    pvr: Get rid of dummy fields in prim headers
    
    Those dummy fields were added to the various primitive headers to make
    sure that they had the correct size.
    
    Now that all primitive headers use the same pvr_poly_hdr_t type, which
    has the correct size even with the dummy fields removed, all the dummy
    fields can be removed.
    
    Note that the driver code was setting them either to 0 or 0xffff'ffff,
    for some reason. Given that this was written almost 25 years ago and
    everything seems to work just fine without writing those fields, it
    seems safe to drop them.
    
    Dropping them also fixes #1034, which happened since the switch to the
    common pvr_poly_hdr_t type, and was caused by the dummy fields moving
    around (as prior to that, the d1/d2 fields in a pvr_poly_mod_hdr were
    at different offsets than the d1/d2 fields in a pvr_poly_hdr, for
    instance).
