Three fixes, all of them things the new hardware tests turned up.
sceMd5Block* and sceKernelUtilsMd5Block* shared one static md5_context and ignored the context
pointer the caller passed in, with a TODO saying it would do "unless games do several MD5
concurrently". hash/md5ctx shows a real PSP keeps everything in the caller's 96 bytes and happily
runs two digests at once, so do that instead: the state, the counters and the block buffer now
live at ctxAddr in the game's own memory, in the layout the test pins down. Two interleaved
digests come out right, and a context that gets copied mid-digest carries on correctly. As a
side effect the state is now covered by savestates, which a file-static never was.
MersenneTwister masked both halves with 0x80000000 where the low half needs 0x7FFFFFFF, so
sceMt19937UInt and sceKernelUtilsMt19937UInt were returning a sequence that isn't MT19937 at
all - every number differed from hardware from the first draw. hash/mt19937ctx computes the
reference sequence itself and confirms the PSP is plain MT19937; with the mask fixed we match it
for both seeds tested. Init also twists the array immediately, as hardware does, so a context
that has been seeded but not drawn from now holds what a real one would.
sceKernelCreateTlspl accepted partitions up to 9 before falling through to the permission check.
Hardware draws the line at 6 - threads/tls/create records 7, 8, 9 and 10 all returning
ILLEGAL_ARGUMENT - so 8 and 9 were coming back ILLEGAL_PERM. Note this is genuinely different
from sceKernelCreateVpl right above it, which does let 8 and 9 through to ILLEGAL_PERM; the two
had been sharing a check that was only ever right for Vpl.
Risk worth naming: the MT19937 change alters the numbers any game gets from these calls. That's
the point - they were wrong - but a savestate taken mid-sequence will resume with a generator
that behaves differently from the one that made it.
