Account id 0 or a null output returns SCE_NP_ERROR_INVALID_ARGUMENT;
otherwise the always signed-out NP returns SCE_NP_ERROR_SIGNED_OUT, as
sceNpGetAccountIdA does. PPSA14632 imports it.

sceNpRegisterStateCallback and sceNpRegisterStateCallbackA stored nothing,
the unregister calls always succeeded and sceNpCheckCallback did nothing,
so a title that waits for its NP state callback never learned the user's
state. #1277 reports that Minecraft Preview (PPSA19639) needs the callback
(stop 2).
sceNpRegisterStateCallbackA now keeps up to 8 callbacks and returns the
slot plus 1. A null callback returns INVALID_ARGUMENT, a callback that is
already registered CALLBACK_ALREADY_REGISTERED and a ninth one
CALLBACK_MAX (0x8055001D). sceNpUnregisterStateCallbackA returns
INVALID_ARGUMENT for an id outside 1..8 and CALLBACK_NOT_REGISTERED for an
empty slot. The legacy sceNpRegisterStateCallback keeps one callback with
the same errors. The rules follow shadPS4
src/core/libraries/np/np_manager.cpp @15abf68c9b52 (RegisterStateCallbackA
and UnregisterStateCallbackAById L857-L901, the legacy pair L981-L1005,
ORBIS_NP_STATE_CALLBACK_MAX L36) and np_error.h L38.
Each registration is marked pending. sceNpCheckCallback takes the pending
registrations under the lock and calls them after releasing it, on the
calling thread, with SIGNED_OUT for the initial user 0x10000000. For the A
form this follows KytyPS5 src/libs/network.cpp @9e41d8320a27
(NpRegisterStateCallbackA L4021-L4034 marks the registration pending,
NpCheckCallback L3959-L3974 delivers it once). KytyPS5 never calls the
legacy callback (NpRegisterStateCallback and NpUnregisterStateCallback,
L4009-L4019, do nothing). The legacy callback is called as
(user, SIGNED_OUT, nullptr, userdata), as in shadPS4, which passes an NpId
only for SIGNED_IN (L823, L938-L940).
shadPS4 queues SIGNED_OUT from the user service login event instead
(DispatchPendingNpStateCallbacks L903-L962), and the same event calls the
reachability callback once with UNAVAILABLE (L922-L931, L959-L961). The
reachability callback is still not called here. These differences and the
unmeasured console behaviour are recorded in
docs/dev/debt/libSceNpManager.md.

Validate timeout arguments and track live requests so unknown or deleted
ids return REQUEST_NOT_FOUND. This supplies the remaining absent load
import alongside the dialog Close export; timeouts follow the existing
offline network model and are not stored.
