Oleg Dubinskiy 99d4824c6f [NTUSER][USER32] Make possible to set custom mouse cursors 
[NTUSER]

    - Implement SPI_SETCURSORS case for SystemParametersInfoA/W. According to MSDN, it updates the system mouse cursors by the ones provided by user (can be set via main.cpl). It does not use any parameters from SystemParametersInfo:

    1. First, get the cursor path from user defined values in registry via win32k!RegReadUserSetting.
    2. Then load the cursor handle from the specified cursor via user32!LoadImageW called from the aprropriate win32k callback via KeUserModeCallback.
    3. Set received handle for an appropriate resource ID via win32k!NtUserSetSystemCursor. Do this for each system defined cursor.

    - NEW: Call an internal handler for SPI_SETCURSORS from win32k!SpiUpdatePerUserSystemParameters, to reload user-defined cursors from Registry after reboot. This is called from WinLogon at each startup.
    - Implement co_IntLoadImage callback for user32!LoadImageW. Add an appropriate part in user32 also.
    - Rewrite co_IntSetupDefaultCursors callback, responsible for default (system) cursors loading. Call a callback to user32!LoadImageW, to load each system cursor, and then use win32k!NtUserSetSystemCursor to set each of them as the current system cursor.
    - Refactor some other several cursor/icon functions: NtUserFindExistingCursorIcon, NtUserSetSystemCursor and DefWndHandleSetCursor.
    - Handle HTHELP case in win32k!GetNCHitEx and user32!CreateDialogIndirectA/W, which is responsible for help button class. Set an appropriate cursor for this case in DefWndHandleSetCursor (DefWindowProc!WM_SETCURSOR message).
    - Remove bogus WM_SETCURSOR handing from win32k!DesktopWindowProc and user32!DesktopWndProcW, since it does not load a proper cursor at all, only default IDC_ARROW. It is already handled properly in win32k!IntDefWindowProc.
    - Set correct GreSetPointerShape flags for animated mouse cursors.
    - NEW: Add the system timer for animated mouse cursors where an each frame is enumerated separately and call it from win32k!UserSetCursor. This allows *.ani cursors to actually animate.

[USER32]

    - Add/fix user mode parts of LoadImage and SetDefaultCursors callbacks. Don't try to load system cursor scheme, it should be done in main.cpl instead.
    - Handle animated mouse cursors (*.ani). Load them correcly in user32!CURSORICON_LoadFromFileW. We already have CURSORICON_GetCursorDataFromANI, which handles it properly. Also set the correct flags for CURSORDATA structure and enable CURSORF_ACON flag on cursor creation in case cursor is animated.
    - NEW: Load user-defined cursors from HKCU\Control Panel\Cursors Reigstry key. Call it from user32!ClientThreadSetup, to load a cursors at each startup.
    - NEW: Add a small workaround to user32!LoadCursorW: try to find and load current cursor from Registry set by user first, in case it is set. Only in case it was not found, continue normal execution: load default system cursor, as the function should do. This allows to properly load the correct cursor for all UI elements.

Remaining bugs/issues:

    - Animated cursors always have a bit wrong position compared to Windows. However it's absolutely correct for standart cursors (with a *.cur extension).
    - Sometimes the animation becomes too fast (perhaps because of a recusrsive win32k!IntSetTimer calls, need it some another condition to kill the timer?).
    - In case of changing *.cur -> *.ani, sometimes the animation is continuing infinitely on some UI elements (or in the window where the previous *.ani cursor was initially set), even after cursor is changed. Needs to restart an app/explorer/etc. to avoid the problem. However, this does not occur when changing *.cur -> *.cur, *.cur -> *.ani and *.ani -> *.ani. Again, it seems to require one more condition to kill the timer.
