winhelp: We can reference any page in HLPFILE_BrowsePage(). Perform similar change in HLPFILE_DoReadHlpFile() for the symmetry.

This makes the code check that the buffer is big enough to read from 
before copying the data from it. The safe_buffer_increment call is still 
needed for the case where we point the memory to the buffer, so move the 
call there.

dinput: joystick test: Improve reporting when enumerated axes/buttons/POVs don't match capabilities.

wined3d: Let WineD3D_ChoosePixelFormat operate on the pixel format database we store at WineD3D startup.

wined3d: Store more information about pixel formats. This is needed for some WineD3D_ChoosePixelFormat restructuring.

This reverts commit 33e561f5.
Fixed the test that fails on all platforms.
