scanline sync: hand the vblank clock to the frame thread by seqlock, not a lock

The vblank clock was shared under an slock: the kernel-event thread
took it once per vblank to feed the clock, and the frame thread took it
two or three times a frame to read the beam. Uncontended that costs
little, but it lets the frame thread wait behind the time-critical
clock thread, and the house pattern for a one-writer snapshot read by
another thread is a seqlock - video_driver.c's frame cache, the
viewport, the shader sensor uniforms.

The clock has exactly one writer at a time: the kernel-event thread
while it runs, the frame thread otherwise (the DWM and DirectDraw
sources, and every reset). Every source switch stops the thread before
the frame thread writes and starts it after, and thread start and join
order that handover, so the writer's clock is plain memory. What the
frame thread reads is a published copy:

- vblank_clock_publish() / vblank_clock_snapshot(), in vblank_clock.h:
  a stamp made odd around four relaxed 64-bit and int stores - the
  period and nominal rate as the bits of their doubles - and a reader
  that retries against a publish in progress up to 64 times, then
  takes "no clock this once". The same shape and bound as the frame
  cache's. The writer never waits and the reader never blocks.

- Available where retro_atomic is lock-free and 64 bits wide, which
  both MinGW targets are - on 32-bit x86 the 64-bit fields ride
  cmpxchg8b, which every processor Windows 2000 runs on has. A build
  without them keeps the lock, as the frame cache does.

The DirectDraw source, whose writer is the frame thread itself, reads
its own copy instead of the snapshot.

samples/gfx/vblank_clock/vblank_clock_pub_test: one writer publishing
two million clocks flat out, each built so its fields agree with each
other, and three readers checking every snapshot is one whole publish
and that none goes backwards. Five to six million snapshots, none torn
or backwards; clean under ThreadSanitizer, ASan and UBSan, and run
under TSan in the samples/gfx job. (Under TSan's slowdown about 5% of
reads hit the retry bound against a writer that never pauses; the real
one publishes once a vblank.)

-name: CI removed struct members
-
-# When a struct member goes away, the compiler finds every reader it
-# compiles. The readers it does not compile are the ones no Linux box
-# sees - the Objective-C drivers above all, and anything behind a
-# platform #ifdef - so each of those is found by whichever job builds
-# that platform, one round trip at a time.
-#
-# window_position_x and window_position_y went that way. Packing the
-# pair into one word updated the Win32 and SDL3 users, which is what a
-# grep of the .c and .h files turns up; ui_cocoa.m kept reading both
-# and took out the macOS job and both PowerPC cross jobs at once. Those
-# three are among the slowest jobs in the tree, and the answer they
-# eventually gave was four lines in one file.
-#
-# tools/packed_field_check.py does not cover this. It knows the six
-# names a size or origin pair is spelled with, and window_position_x is
-# not one of them; on the broken tree it printed 1184 lines, none of
-# them ui_cocoa.m. The question here is not what a member is called,
-# it is whether anything still reaches for one the change took away.
-#
-# So this lane reads the change rather than the tree's vocabulary: the
-# members a push or a pull request removes, minus the ones something
-# still declares, against every reader in every language the tree is
-# written in. It reads files rather than building them, so one job
-# covers what the platform jobs between them would only find one at a
-# time.

-# retro_procbarrier picks one of several ways to force a memory barrier
-# on every running thread, and which one depends on the OS and the CPU.
-# The Linux samples job only ever runs the one its runner picks
-# (membarrier). This runs every tier each platform has, on a multi-core
-# runner so the fence checks can actually catch a missing barrier, and
-# fails if a forced tier quietly fell back to another one.

 - MENU/XMB: Tab change possible by gestures
 - MENU/XMB: Horizontal menu is now optional
 - NETWORK: New network commands SAVE_STATE_SLOT N and GET_CONFIG_PARAM
-- NETWORK: HELP network command lists every command with what it does
-- NETWORK: LIST_CORES, LIST_PLAYLISTS and GET_PLAYLIST network commands, to find content and the core to load it with
-- NETWORK: MCP server: AI assistants can drive RetroArch through the Model Context Protocol, every network command a tool (off by default, see docs/mcp-server.md)
-- NETWORK: Built-in TLS 1.2/1.3 client; mbedTLS and BearSSL are no longer bundled (--enable-mbedtls / --enable-bearssl use a system one)
-- NETWORK: Built-in SMB2/3 client with signing, AES-CCM/GCM encryption and Kerberos; libsmb2 is no longer bundled (--enable-libsmb uses a system one)
-- NETWORK: Built-in NFSv3 and NFSv4 (4.0, 4.1, 4.2) client for loading content from nfs:// exports
-- NETWORK: NFS files stay usable across a server restart, a dropped connection or a long pause: the client reconnects and reopens what it needs
-- 3DS/VITA/SWITCH/WIIU: nfs:// content through the built-in NFS client
-- 3DS/VITA/SWITCH: smb:// content through the built-in SMB client
-- WINDOWS/MSVC: the Visual Studio 2005 - 2017 projects build the TLS client, the keychain, SMB and NFS
-- NETWORK: SMB files stay usable across a server restart: the connection is mended and the file opened again where it was
-- NETWORK: NFSv4.2 reads use READ_PLUS: holes in sparse files no longer cross the network
-- 3DS/SWITCH: nfs:// content through the built-in NFS client
-- NETWORK: Optional SMB/NFS read-ahead with background prefetch, for large disc images over a slow link (off by default)
-- NETWORK: Saved passwords are encrypted in retroarch-keychain.cfg; an optional passphrase lets the keychain move to another machine (see docs/network-stack.md)
-- NETWORK: SMB 3.1.1 signs with AES-GMAC where the server offers it, several times faster than AES-CMAC on signed reads
-- NETWORK: HTTPS downloads whose length is set by the server closing the connection now finish instead of hanging
 - OVERLAY: Allow overlays to position the viewport
 - OVERLAY: Hold button function
 - OVERLAY: Allow interaction during next overlay swap

CODING-GUIDELINES

@@ -268,16 +268,6 @@ Debug builds report handlers that overrun a frame - see
 task_queue_set_slow_handler_cb() - which is the cheapest way to find
 out whether a handler you are adding respects any of this.
 
-The waits that remain are the accepted ones, none of them reachable
-while the menu is up or a core runs, each commented where it is:
-  * the command-line scan without a menu, which exits once done
-    (retroarch.c);
-  * the save/load state waits on exit, at startup and when an init
-    fails (content_wait_for_save_state_task() and
-    content_wait_for_load_state_task());
-  * the Wii U main loop's vsync wait (platform_wiiu.c).
-Win32 file dialogs are modal by nature and stay so.
