sceRudpEnd takes no argument and shuts the library down; sceRudpTerminate
takes a context id and releases that context. main had the two swapped,
so a title calling sceRudpEnd() passed a stray register as a context id
and the library stayed initialised.
Evidence:
- PS5 console measurement by hugodearaujo in #3073 (firmware 13.60):
"After `sceRudpEnd()` all three return `0x80770001` again"
(sceRudpGetMaxSegmentSize, sceRudpProcessEvents, sceRudpNetFlush).
- AlexAltea/orbital cc408367da6a6ebbf5ac1ac559fefeadc73b2831
tools/ida/db_types.json:1971,1996: `int sceRudpEnd(void)`,
`int sceRudpTerminate(int ctxId)`.
- RPCS3 26098fb42d090cd522b4afcf3b754dd987c82978
rpcs3/Emu/Cell/Modules/cellRudp.cpp:108: `cellRudpEnd()` tears the
library down.
- AndnixSH/Vita3K-PS-Vita-OS-Fork c86ac732bc811057e690bed280c5076bdf95385e
vita3k/modules/SceRudp/SceLibRudp.cpp:1032,1614: `sceRudpEnd()` clears
every context, `sceRudpTerminate(int ctx_id)` erases one.
The bodies are unchanged, only exchanged. guest_offline_imports now ends
the library with sceRudpEnd(), and guest_rudp_status checks that
sceRudpTerminate releases one context and sceRudpEnd all of them.

Measured on a PS5 (firmware 13.60):
- sceRudpInit rejects a null pool or a size of 0 or less with
INVALID_ARGUMENT, and a pool under 0xC58 bytes or not 8-byte aligned
with MEMORY (0x80770007).
- sceRudpGetStatus rejects a null pointer or a byte count of 0 or above
0xF8 with INVALID_ARGUMENT and reports the live context count at 0x64.
