An indexed draw that binds its index buffer in place from a host import
(#2253) scans the bound range for its highest index on every draw, where
the copied path reuses the value kept with its snapshot. A draw of many
indices pays for the scan each time, and an indirect draw, which binds
the whole declared index buffer, scans the whole buffer per draw.
The recorder now keeps the highest index of an in-place index range of
4096 indices or more with the write generation collected before the
scan, and a draw takes it while the range is unchanged since
(GuestMemory::UnchangedSince and the allocation registry generation, as
for a reused snapshot). A smaller range is scanned at every draw as
before: the scan costs 0.4 ns per index and the write collect and lookup
0.2 to 1.4 us per draw, so the scan is the cheaper of the two below
about 3,000 indices, as #2253 measured on small ranges.
Resident Evil 4 (PPSA07411, #2776) and PRAGMATA (PPSA02530, #3043) stop
on the absent export with
what(): _ZN3sce4Json14InitParameter225setSpecialFloatFormatTypeENS0_22SpecialFloatFormatTypeE not implemented
Deathloop, Minecraft Legends and Cyberpunk import the base-object
constructor InitParameter2::InitParameter2(), InitParameterRtti2::
setAllocatorRtti and InitParameterRtti::InitParameterRtti(AllocParamRtti*,
void*, unsigned long), which were NotImplemented stubs.
InitParameter2 is the 40-byte object of SharpEmu and KytyPS5: the
allocator, its user data, the file buffer size and the 32-bit special
float format type at 0x18. Both constructors zero it, setAllocatorRtti
writes the allocation parameters and user data where setAllocator writes
the allocator, and setSpecialFloatFormatType stores the type.
InitParameterRtti's constructor writes its three arguments to the first
24 bytes. The NID WVZBP4IyM+E recomputes from the mangled name and is in
the aerolib database. The enum's values are unknown, so no value is
rejected; the inferred layouts are recorded in TechnicalDebt.

scePthreadKeyCreate and pthread_key_create handed out the slot index,
so the first key in a process was 0. FreeBSD libthr returns slot + 1
(_pthread_key_create: "*key = i + 1") and subtracts 1 again in
pthread_key_delete, pthread_getspecific and pthread_setspecific, so 0 is
never a valid key. Code that keeps 0 as "key not created yet" therefore
created a new key on every call and lost the values it stored under the
previous one.
Keys now start at 1; 0 and other out-of-range keys are rejected with
EINVAL by delete and set and read as NULL, as before.

exp2 set errno (34) for 1024.0. FreeBSD msun never sets errno and
reports errors through floating-point exceptions only, so errno is now
saved and restored around the host call.

sceKernelClose passed every descriptor to the host close. Guest socket
descriptors start at 0x10000000 and are not host descriptors, so closing
an open socket returned SCE_KERNEL_ERROR_EBADF and left it in the guest
socket table with its host socket open. Route them to GuestSockets::Close
as close, sceKernelRead and sceKernelWrite already do; a closed socket
still returns SCE_KERNEL_ERROR_EBADF.

sceContentExportStart hands out positive session ids, at most 10 live
(SharpProspero MaxExecution), and sceContentExportFinish closes them.
sceContentExportGetProgress, sceContentExportCancel and
sceContentExportFromDataWithThumbnail take their Orbital signatures and
check the session. The host has no media library to export into, so
FromDataWithThumbnail throws before it calls either data callback, and
GetProgress and Cancel throw for a live session since no export ever
runs and their result for an idle session is unknown. An eleventh Start
and Term with live sessions throw.
Titles: Cult of the Lamb PPSA06465 imports GetProgress, Cancel and
FromDataWithThumbnail (#2686); PPSA21564 (#271) and Cyberpunk 2077
PPSA04029 (#266) import Start.
Sources: Orbital tools/ida/db_types.json (cc408367) for the signatures,
SharpProspero Interop/Content/ContentExport.cs (5dfdb4b0) for the
session model and MaxExecution, shadPS4 content_export.h (443f0224) for
the parameter and callback layouts.

(cherry picked from commit 473d6dd355d2c0ee22f9792927e0e465846569cf)
PPSA07411 (Resident Evil 4) fails to load without these imports. Their signatures are unknown, so they are declared without parameters and throw until they are implemented. Adds a TechnicalDebt entry.

End clears the init flag set by sceVoiceQoSInit and returns 0, so the
library can be initialized again. Before an initialization it returns
0x804E0901 (LIBVOICEQOS_NOT_INIT), as measured on a PS5 (firmware 13.60)
in #1407.
LEGO Horizon Adventures (PPSA14632) calls it at shutdown and Ghost of
Yotei (PPSA26344) calls it on its sceVoiceQoSInit failure branch.
