Cygwin/X: Implement framebuffer resizing in RANDR extension

Implement framebuffer resizing in RANDR extension:

Resize the frame buffer, the screen's root window and the native window
containing the root window image.

Correctly allow for decorations in new native window size when resizing native window
to fit the new framebuffer size with AdjustWindowRectEx()

Update physical size info for a screen when it is changed by RANDR

Forbid client-requested RANDR changes in fullscreen and rootless modes

Only resize window on an external RandR request, to avoid recursing on
a WM_SIZE requested resize.

Also, add prototypes for winRandRInit() and winDoRandRScreenSetSize() to header file

Also, update the author list and copyright for winrandr.c
