This is an addendum to
0.4.15-dev-3174-g dda9c3979e CORE-17769 and
0.4.15-dev-3147-g 3bf7e3ac13 CORE-17754 CORE-17755
We have not seen this happening in real-life yet, but some code-fragments within co_IntSetScrollInfo()
e.g. line 628 if (nBar == SB_CTL) do clearly indicate that nBar can be 2 (SB_CTL).
Some lines below we definitely must not access those 4 static arrays out of bounds then via nBar as access index!
Ftr with a bit of grepping I also found some calls like NtUserSetScrollInfo(Wnd, SB_CTL, &Info, FALSE);
e.g: in win32ss/user/user32/controls/scrollbar.c so I am pretty sure nBar == 2 can happen in practice within co_IntSetScrollInfo().
I question whether any of those reads/writes to those static arrays (or the comparisons) would make any sense on index 2,
so we should aim to eliminate them altogether in the future.
Fixes CORE-17769 'Rapps Listview manual resize may erroneously not draw the triangles sometimes'
This could happen for both: themed and unthemed.
CORE-17769 was a regression introduced by 0.4.14-dev-1134-g 00adb1a3f9
We don't really like the added state in form of the static variables,
but the patch works good from a pure testing-perspective.

- Do the kernel/server --> user/client-space pointers conversion within
NtUserProcessConnect(), instead of having the callers of this function
doing this job.
This makes the behaviour Windows-compatible.
NOTE: the gHandleEntries pointer is ReactOS-specific!
- Drop the g_ulSharedDelta global, just use instead gSharedInfo.ulSharedDelta.
- Add extra documentation aspects for NtUserProcessConnect() that are
not yet implemented in ReactOS.
- Improve User32InitializeImmEntryTable function and related.
- Complete win32ss/user/user32/include/immtable.h table.
- Delete a hack in user32.DllMain and apply my magical tricks. This will fix some access violations in IMM32.
- Add some stubs into IMM32.

DLGWINDOWEXTRA is 30 (both on win32 and win64). This has storage for the following entries: DWLP_MSGRESULT (0), DWLP_DLGPROC (8), DWLP_USER (16)
We used to store the dialog info pointer using SetWindowLongPtr (DWLP_ROS_DIALOGINFO == DWLP_USER+sizeof(ULONG_PTR) == 24), which was fine on win32, but failed on win64, since there wasn't enough space left (24 + 8 = 32 > 30).
Rewrite the way the DLGINFO pointer is stored, by adding an additional field to the WND structure and set it using NtUserxSetDialogPointer (which is what it is for).
Also fix too small cbWndExtra for the button class.

Thanks goes to I_Kill_Bugs for the patch (and partly to Kyle Katarn for the PR) and Hermes for tweaking the patch code. Had to make a commit myself as the PR author's account is deleted.
