The registers that are saved/restored in the trap / exception frame need to be consistent between all entry/exit points as well as the functions that convert between trap/exception frame and context. The trap frame contains only the non-volatile registers and rbp, the rest is saved in the exception frame.
The previous code didn't save rbp in the syscall handler, which led to it being clobbered when exiting though KiServiceExit2 rather than returning back to the syscall exit path. Also KeContextToTrapFrame would use rbx, rsi and rdi from the trap frame, which wouldn't be saved there by the syscall handler.
This fixes invalid contexts being passed to RtlDispatchException. Also update the ExceptionAddress field in the EXCEPTION_FRAME, to match the Rip value in the CONTEXT, which is required for proper unwinding.
This saves a few bytes in the binary, e.g.
regedit.exe master 0.4.15-dev-7887-g64a59a1 RosBEWin2.2.2 GCC8.4.0 dbg x86 shrinks
from 1.049.600 bytes to 1.049.080 bytes.
Furthermore it syncs the translations at this line, because es-ES.rc even translated that identifier to "Lista1" already.
This prevents an issue where clicking on most of the icons on the desktop
that isn't the file explorer causes explorer to throw an exception,
and also prevents another issue where most applications won't launch from the start menu;
at least on MSVC builds running on VirtualBox 5.2.44.
^- I am pretty sure, that this was not always the case. The guilty rev is yet unknown though.
Follow-up to #6721. This PR can reduce 1KB of
binary size.

- Delete CStubFolderBase and derived classes.
- Add
CDesktopFolder::_ParseDisplayNameByParent
method.
- Don't use excessive IShellFolder objects in
parsing display names.
- Simplify and reduce code.
- For NT6.0+, NTDLL exports those hash APIs that ADVAPI32 thunks forward to
- Fix undocumented context structure layout and content
- Add apitests to verify both of hash result and structure content
Add a check so that mouse move messages are not generated unless
the mouse cursor X or Y position is changed.
This fixes extra mouse moves generated when clicking.

The it-IT.rc thingy I spotted when I wanted to port back the regedit-changes from
0.4.15-dev-6592-g 995d255962
The line definitely got improved by that commit, but it was still inferior.
In the other 3 langs it is just some stuff where master head is inferior to older branches,
I spotted them while porting back other things.
So I placed the FIXMEs to protect myself from porting it back accidentally,
and to help the native speakers with seeing them on master head.
The tr-TR.rc: "D&izi Değeri" -> "D&ize Değeri" was done for consistency, because we do have
that item 3 times, and 2 of them were using "D&ize Değeri" already.
[MMIXER] Implement hadling WAVE_FORMAT_EXTENSIBLE audio format
Fix opening audio device error when trying to open it with WAVE_FORMAT_EXTENSIBLE format tag set in wFormatTag member of WAVEFORMATEX:
- Pass additional data size from WAVEFORMATEX.cbSize to pin data format.
- Append it to the whole size of pin data format (KSDATAFORMAT.FormatSize).
- Set additional fields in WAVEFORMATEXTENSIBLE structure (data format, BPS and channel mask) when WAVE_FORMAT_EXTENSIBLE is used. They are used by our inbuilt Intel AC97 miniport driver at least. It simply fails when these members are not set.
- Fix pin connect allocation size by appending an additional data size from WAVEFORMATEX.cbSize to KSPIN_CONNECT + KSDATAFORMAT + WAVEFORMATEX. This allows to proerly initialize additional extensible data and avoids kernel memory leakage when using extensible audio format.
- Remove format tag check which allowed WAVE_FORMAT_PCM to be opened correctly. So now all possible audio formats can be opened properly at least (although it does not mean they may work correctly).
This fixes the audio playback for all apps those are supporting extensible audio data and use it by default (e. g. AIMP 5.30, QMMP 0.12.17, all Chrome/Chromium-based browsers, GameDev Tycoon Demo game etc.).

* [KS] Allow passing additional extensible audio data when extensible audio format is used
- Append additional data size from WAVEFORMATEX.cbSize to pin connect size passed to KsCreatePin. If the tag is WAVE_FORMAT_PCM, then this member should always be zero. So in that case, no any additional data is passed to creation request, and the passed data size is correct for PCM too (KSDATAFORMAT + WAVEFORMATEX).
This fixes audio playback in several apps those are supporting extensibble audio and use it by default (e. g. AIMP 5.30, QMMP 0.12.17, all Chrome/Chromium based browsers, GameDev Tycoon Demo game etc.).

* [WDMAUD.DRV] Pass the correct additional data size to I/O control request
Store a correct size of additional data in WAVEFORMATEX.cbSize when performing open of audio device, when WAVE_FORMAT_EXTENSIBLE audio format is used.
It allows to properly open audio device with Legacy APIs enabled too.
This fixes audio playback in several apps those are using extensible audio data (e. g. AIMP 5.30, QMMP 0.12.17, all Chrome/Chromium based browsers, GameDevTycoon Demo game etc.).

First an foremost this fixes "the copies-icon in the print-dlg not showing" for Taiwan as well.
That part is an addendum to 0.4.15-dev-3493-g a36cc8054d (#2831)
Taiwan is untypically placed in cdlg_Zh.rc as well for comdlg, next to the traditional chinese version and therefore was forgotten.
Furthermore improve many translations a little bit, where strings could be stolen from neighbor controls. This part focuses mostly on the NEWFILEOPENV2ORD.
Then add many FIXMEs for existing accelerator collisions, many of them were introduced by adding the "Help"-button retrospectively, when other translations existed already. Let the native speakers handle them later.
Strip accelerators from some "Cancel" buttons, e.g. in cdlg_Pt.rc, and the "Save as" button, e.g. within cdlg_Es.rc as those should not exist, which most languages did properly respect already.
Also fix a few text truncations and a few accelerators, e.g. for de-DE: stc3 was cutoff, and "Öffnen" had the wrong accelerator.
This replaces the usage of FIELD_OFFSET for dynamic indexing into array fields.
Sadly GCC has broken __builtin_offsetof and they don't seem to intend to fix it.

We need to save the missing registers in the trap frame before calling KiInitiateUserApc, because they will be used to create the CONTEXT that is saved on the user mode stack, where KiUserApcDispatcher returns back to using NtContinue. This fixes remaining failures in kernel32_apitest QueueUserAPC.
Both due-times and interrupt time are unsigned, but were treated as signed in KiInsertTimerTable, which led to very long (e.g. INFINITE) waits being interpreted as having a negative due-time and being completed instantly.
Mostly fixes kernel32_apitest QueueUserAPC
This is used in KiUserModeCallout instead of KiServiceExit2. The latter is broken, leaks non-volatile registers and will need to be modified to handle an exception frame, which we don't need/have here. It will also use sysret instead of iret and is generally simpler/faster.
Eventually it would be desirable to skip the entire trap frame setup and do everything in KiCallUserMode. This requires some cleanup and special handling for user APC delivery.
Fixes CORE-19505 'game "Hover!" from rapps does not start anymore'
It failed showing a msgbox
"There was an error allocating memory in Hover!"
the regression was introduced by
0.4.15-dev-5602-g c47506a5f4
Add missing heap initialization in DllMain entrypoints of msvcrt20.dll and msvcrt40.dll,
similarly to as it is done in msvcrt.dll (CRT).
The msvcrt.dll (CRT) initialization code was updated properly
during the last winesync, accordingly to the new changes,
but msvcrt20.dll/msvcrt40.dll one was not. So update it too.
This fixes the crash of HOVER 1.0 game from Rapps when
it tries to allocate a dynamical memory from the
unitialized heap via malloc() function exported from our msvcrt20.dll.
This is intentionally not part of ntdll_apitest, because that links to advapi32, which links to rpcrt4, which (wrongly!) links to ws2_32, which (wrongly!) links to user32, which breaks the test.
This fixes CORE-19497 'Regression, part of the statusbar with the sizegrip is not redrawn properly'
The regression was introduced / unhidden by 0.4.15-dev-5617-g 7866eb2886

This can fail on optimized builds, where functions can end after a noreturn function call without an epilog / ret, but with an int 3. We simply fail gracefully, which is the right thing to do.
This also fixes delivering APCs from the system call handler, which previously would have clobbered rax. Also don't use the thread's TrapFrame member, which is not always set, when returning.
