They use the same quadratic interpolator as rcp and friends, with three
twists. sin indexes the quarter wave from the top, and asin and sin work
in a per-segment exponent whose 4-ulp truncation also applies to results
in a lower binade. log2 truncates exponent + log2(1.m) toward zero to 22
significant bits, and where that step is coarser than 2^-24 the datapath
drops coefficient bits to match; that also covers the region just below
1.0 that needed a special case.
vfpu_sincos now reduces the angle once. With every table gone, so are
the asset folder, the loader, InitVFPU and the fallbacks for tables that
failed to load. All seven functions are bit-exact with the table-based
code over every 32-bit input.

The four share one quadratic interpolator: 128 segments picked by the top
7 bits of the input, each with a constant, a linear and a squared-term
coefficient, and a squarer on the top 10 bits of the rest that rounds t^2
up to a multiple of 256. 128 small coefficient sets per function
replace the 1 MB of delta tables. Derived from the output of the
table-based code, and bit-exact with it over every 32-bit input.

There are a few games that seem to rely on performance problems or
timing quirks to hold the correct pace when playing sceMpeg - have not
been able to nail down any other timing mechanism.
This adds a timing enforcement function.

Follows each language file's own word for firmware rather than imposing one, so
this reads the way the neighbouring strings in [System] already do: fastvare in
Norwegian, systemprogramvara in Swedish, laiteohjelmisto in Finnish, proshivka
in Russian and Ukrainian, and the English word where that is what the language
has settled on.
Thirteen files keep the English string as a placeholder. Those are the ones with
no translation for the firmware strings already in that section either, so there
was no house style to follow and guessing would leave nobody able to check it.

The five new [System] keys, in the 33 languages that already had a rendering of
"firmware" to follow - they disagree on it (fastvare, prosjivka, systemprogramvara,
laiteohjelmisto), so each one matches whatever its own file already chose. The
other 13 fall back to English.
Firmware screen: call it "Uninstall firmware", not "Erase firmware"
Translate the rest of the firmware screen strings
"Uninstall firmware", "No firmware installed" and "Launch XMB", in the same 33
languages as the auto-install strings. XMB stays untranslated - it's Sony's
name for it, and pl_PL already wrote it bare.

36 languages, following each file's existing handling of the sibling RAIntegration
string - most keep the name as-is, pl_PL uses "Integracja RA", tr_TR "RA Entegrasyonu",
ja_JP "RAインテグレーション" - and its formality. The rest are left to fall back to
English rather than guessed at.

RAIntegration keeps its cache and local achievement data next to the
executable. If PPSSPP is installed somewhere that needs elevation to write -
Program Files being the obvious case - that write fails and takes the emulator
down as soon as a set or code notes are loaded, with no log to show for it since
the log can't be written either.
Check whether the exe directory is writable before handing the DLL to rcheevos,
and if it isn't, say so and point at the portable .zip instead. Achievements
themselves still work, so carry on to the normal login.

31 languages, following each file's existing chat terminology (chatt,
bate-papo, obrolan, sembang, 聊天, الشات, ...). The rest are left to fall
back to English rather than guessed at.

The file holds the Hebrew strings in visual order, for renderers with no bidi
of their own, but only 101 of its 269 Hebrew entries were actually a reversal
of he_IL. The rest were left unreversed, reversed by word instead of by
character, or garbled outright ("Win" read as gibberish either way round).
Derived them all mechanically instead. The transform reproduces the entries
that were already right, and keeps as single units the things that must not be
spelled backwards: the \n escape, %N placeholders, runs of Latin and digits,
and an & accelerator together with the character it marks.
The [Dialog] save/OSK strings are the exception - he_IL already stores those
reversed, since PPGeDraw draws them and has no bidi, so the invert file just
mirrors he_IL for those 22 keys.

Adds GameInfoFlags::BUNDLED_UPDATE_INFO, holding the version, title, size
and timestamp of the updater in PSP_GAME/SYSDIR/UPDATE. It comes from the
PARAM.SFO and the directory entry next to the archive, so it's a couple of
small reads on the ISOFileSystem the worker already has open - no
decryption, and DATA.BIN itself is only sniffed for its magic. Only
computed for ISOs; everything else is marked complete with an empty struct.
ISOFileSystem now parses the date out of the ISO9660 directory record,
stored as Unix UTC seconds and reported as the PSP's atime/ctime/mtime.
Those used to always read back as zero, so games calling sceIoGetstat on a
UMD file saw 1900 where hardware gives the mastering date.
Shown on GameScreen as e.g. "Firmware update on disc: 6.60 (2011-10-05),
25.6 MB".

57 strings across nine language files:
* 33 in km_KH where a space snuck in between the % and the digit ("% 1"), plus
one where "%0.2f Hz" ended up as "0.2% f Hz".
* fa_IR "Quick chat %1" had the %1 replaced by a Persian numeral, and ko_KR
"Submitted %1 for %2" lost its %2.
* tr_TR "Earned" had the key translated instead of the value, so the whole
sentence with its four placeholders was replaced by the word "Earned".
The new Turkish string needs a look from someone who speaks Turkish.
* 20 strings across five files that were wrapped in quotes. PPSSPP's ini parser
strips those on load, so nothing changes on screen, but they tripped the
validator.
Turkish writes percentages as "% 0", so the "% <digit>" fix was only applied
where it makes the placeholders match the English string again.

prefersStatusBarHidden was dead code - it computed an orientation and a
(commented out) user preference, then unconditionally returned false. So the
status bar was only ever hidden on iPhone in landscape, and only because iOS
does that on its own in compact height.
Now it honors bImmersiveMode from the DisplayLayoutConfig matching the current
orientation, so it also applies in portrait and on iPad. Adds the corresponding
checkbox to the iOS system settings, and updates the status bar on rotation and
when the setting is toggled.
Also fixes a missing break in the ROTATE_UPDATED case in System_Notify, and a
static/non-static mismatch on sceKernelLoadModuleBufferUsbWlan that broke the
build (the header intentionally exposes it for sceVshBridge).
