sceCoredumpAttachUserFile (5nc2gdLNsok) and
sceCoredumpAttachMemoryRegionAsUserFile (MEJ7tc7ThwM) get the
signatures of Orbital's db_types.json (cc408367) and SharpProspero's
KernelSystem.cs (5dfdb4b0): (uint32_t userValue, const char* path) and
(uint32_t userValue, const void* mem, size_t size, const char* name).
The handler is never invoked here, so both return
SCE_COREDUMP_ERROR_NOT_IN_COREDUMP_HANDLER (0x81180003, shadPS4
coredump_error.h e0a46675) and attach nothing; a null path or name and
a null, empty or wrapping region throw because the order of the
console's checks is unknown.

sceCoredumpWriteUserData (Dbbkj6YHWdo) and sceCoredumpDebugTextOut
(dei8oUx6DbU) get the signatures of Orbital's db_types.json (cc408367)
and SharpProspero's KernelSystem.cs (5dfdb4b0): ssize_t (const void*,
size_t) and void (const char*, int). WriteUserData moves out of
Unimplemented.cpp.
User data belongs to the core dump handler: the Vita's
sceCoredumpWriteUserData returns 0x800A0003 ("No user-data capture is
active") outside it (vita-headers e66ebe90), and the RED engine's PS4
crash handler makes every coredump call from its handler (Vangaurd
4f86d2b0). The handler is never invoked here, so WriteUserData returns
SCE_COREDUMP_ERROR_NOT_IN_COREDUMP_HANDLER (0x81180003, shadPS4
coredump_error.h e0a46675) sign-extended and keeps nothing; a null,
empty or wrapping buffer throws because the order of the console's
checks is unknown. DebugTextOut prints its text to stderr with the
[coredump] prefix; a negative length or a null text with a nonzero
length throws.
Evidence: Broken Sword Reforged (PPSA21480) reaches the family through
its sibling, #3704 comment 6113687542: "`ERROR agc_graphics.cpp:266
Sony call failed with code 8a6c9018` (the resource registration error,
followed by the error dialog), then `sceCoredumpWriteUserString not
implemented`." WriteUserString has no declaration in any source and
keeps throwing; its TechnicalDebt entry records the call. 007 First
Light (PPSA11386) imports WriteUserData (#2523) without calling it
before its stop.
Test: guest_coredump_user_data.
