The memo stamp held TrackerGeneration, which every collect and driver store
advances, so it almost never matched. Driver stores into uncovered ranges
record their generation per 64 KiB block, and NewestStamp of the surface
replaces TrackerGeneration in the stamp.
Implement sceNgs2GeomResetListenerParam and sceNgs2GeomResetSourceParam,
taken from #1021 and limited to the two reset functions. The Geom
structures get their real layouts. sceNgs2GeomCalcListener and
sceNgs2GeomApply stay unimplemented.

PPSA35943 (Graveyard Keeper 2) imports sceHttp2DeleteCookieBox, which no
library exported. On current main the loader stops the title there:
./eboot.elf: symbol lookup error: ./eboot.elf: undefined symbol:
O9ync3F-JVI
sceHttp2DeleteCookieBox(cookieBoxId) erases the box from the handle
registry sceHttp2CreateCookieBox adds it to and returns 0, or the
library's invalid-id error (0x817B1100) for an id that is not a live
cookie box. The signature follows SharpProspero and the behaviour
prosper's sceHttp2DeleteCookieBox; the error code is listed in
TechnicalDebt as not measured on a console.
guest_http2 deletes a box twice, a context id, a box whose context was
terminated, and the two boxes it uses before sceHttp2Term.
With this change the title loads and runs into its asset loading.
Minecraft (PPSA17221) fails to load on nine absent imports. The authorized-app
dialog runs the common-dialog state machine without UI and reports the user
as having cancelled, like the login and VR setup dialogs. The other two,
sceNpAuthGetAuthorizedAppCode and the unnamed libSceSaveData.native NID
RvID8BVeg+g, are declared as throwing stubs with unknown signatures.

RetroArch 1.0.0-beta.1 (PPSA99169) stops on main 0f863c10 at
FAIL: unresolved ELF import Nx-F5v0-qU8 from libSceLibcInternal.prx
Nx-F5v0-qU8 is asinl (tools/nid_names.py, aerolib).
The implementation follows the asinl of the libc.prx bundled with
PPSA28319, read from its disassembly: FreeBSD msun's e_asinl.c with
the ld80 invtrig.c coefficients (9f043204), which the binary holds as
the same 80-bit constants, computed in the x87 long double the guest
uses. +-1 returns +-pi/2 rounded to 64 bits and +-0 keeps its sign.
For |x| > 1, the infinities and NaN, Sony's error helper raises
FE_INVALID and sets errno to EDOM before returning (x - x) / (x - x),
so a NaN argument sets EDOM too.
20 million random arguments in (-1, 1) plus the branch edges give the
same bits as that code from the title's libc.prx run on a Windows
host. guest_math pins a set of those bits and checks the domain
errors' errno and FE_INVALID, and that errno is untouched otherwise.

Ruffle Flash 1.2.0 (PPSA68091) stops on main 0f863c10 at
FAIL: unresolved ELF import 1t1-JoZ0sZQ from libSceLibcInternal.prx
1t1-JoZ0sZQ is sinhf (tools/nid_names.py, aerolib). RetroArch
1.0.0-beta.1 (PPSA99169) imports it as well.
The implementation follows the sinhf of the libc.prx bundled with
PPSA28319, read from its disassembly: FreeBSD msun's e_sinhf.c as of
5aa554c7 (before __ldexp_expf, so expf(|x| / 2) is squared between
logf(FLT_MAX) and the overflow threshold), calling msun stable/9
expm1f and expf (59bc2f09), whose paths for the arguments sinhf passes
are inlined. Past the threshold Sony's error helper sets errno to
ERANGE before returning x * 1e37; NaN and the infinities return x + x
and leave errno alone.
Running that code from the title's libc.prx on a Windows host gives
the same bits as this implementation for every finite argument up to
the threshold, both signs (2,238,032,378 inputs). guest_math pins a
set of those bits, the overflow errno and FE_OVERFLOW, and checks that
errno is untouched otherwise.
