sceNpStrParseHex and sceNpStrnParseHex in firmware 13.60 write the high
nibble of each byte before they read the low digit, so a refused low digit
leaves that byte as the high nibble shifted left by four.

The ten operators allocate an object behind a 16-byte header that keeps its
allocator and free it through that allocator, as libSceNpCommon.sprx of
firmware 13.60 does (read from disassembly, not measured on a console). Five
were NotImplemented stubs; the other five were not exported.

sceNpUtilJsonEscape has to stay inside a partly filled 16 byte buffer and refuse
one without a terminator, sceNpUtilJsonUnescape has to report the length of a
query with a null destination and size 0, and sceNpUtilJsonGetOneChar has to
reject a high surrogate that is not followed by a second unicode escape.
sceNpCalloutStartOnCtx64 cleared and filled the entry before looking for
it in the queue, so restarting a queued callout cut off every callout
queued after it and changed its deadline while the callout thread could
read it. The entry is now written only after the duplicate check under
the context mutex. sceNpArchInit and sceNpArchTerm now hold a lock, so a
second caller no longer returns before the global heap exists. Both
differences from the firmware are recorded in the debt document.

Builds on #9037. Adds threads, event flags, semaphores, atomics, heaps
and kernel memory, callout contexts, time and SDK version queries,
base64 and hex codecs, integer and string helpers, JSON escaping, URL
encoding, online id strings, language codes, title ids and debug output.
The behaviour follows libSceNpCommon.sprx from firmware 12.00, read
from disassembly.
