On Linux and macOS, fcntl and ioctl threw "descriptor N is neither a
file, a directory, a pipe nor a character device" for a host socket that
is not a guest socket. That is what a standard descriptor is when a
service manager connects it to its journal, or when a test runner starts
the process with a socket as stdin; guest_kernel_fcntl's standard input
check aborts then.
A socket is now its own descriptor kind. Its status and close-on-exec
flags go through the host as for a pipe end, FIONREAD asks the host,
record locks and read-ahead hints fail with EBADF as FreeBSD's
kern_fcntl fails them on a descriptor without a vnode, and O_ASYNC
throws as on a pipe.

Implement scePlayerSelectionDialogGetStatus and scePlayerSelectionDialogClose in libScePlayerSelectionDialog, matching the common dialog lifecycle convention across player dialogs, and add unit test coverage in GuestPlayerSelectionDialog.
Compute LDS beyond the device's shared-memory limit lives in a storage
buffer, and its 64-bit atomics took a lock in that buffer. AMD's Windows
driver compiles the lock's acquire and release to s_barrier, which inside
the divergent lock loop pairs with the program's own barriers, so the
device-memory case of agc_driver_lds_lock_budget read half its sum.
With shaderBufferInt64Atomics the device-memory LDS now uses a 64-bit view
of the buffer instead: 64-bit atomics are compare-exchange loops on it and
32-bit atomics stay native, so no lock is taken. Without the feature the
lock is kept. The per-workgroup slice is rounded up to an even dword count
so that the 64-bit view stays aligned.
Homebrew built with the ps5-payload-dev SDK imports by symbol name and
names its system libraries with .sprx, while the libraries in libs/
are .prx files that export NIDs. Quake from the websrv launcher
stopped with 457 unresolved imports such as strlen and malloc.
An import without a module that no searched library exports under its
name is now looked up again under the NID of that name. A dependency
named with .sprx, .suprx or .debug_prx loads the .prx library of the
same stem, and libkernel_web also loads libkernel.prx, as
libSceLibcInternal already loads libc.prx.
Since #4048 enabled robustBufferAccess2, AMD's Windows driver draws
nothing in agc_driver_layered_volume_draw and agc_driver_layered_volume_vertex,
and the selected loads make the high half of agc_driver_subvector_loop's
wave64 skip its loop. Until the cause is found, that driver does not get
the feature, and its loads keep their selections.
