Use intptr_t instead of int when casting from and to XtPointer

Fixes gcc warnings:
Scrollbar.c: In function 'NotifyScroll':
Scrollbar.c:955:37: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
Text.c: In function 'HScroll':
Text.c:1274:41: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
Text.c: In function 'VScroll':
Text.c:1431:31: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
TextPop.c: In function 'DoSearch':
TextPop.c:808:31: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
TextPop.c: In function 'Replace':
TextPop.c:942:31: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
Viewport.c: In function 'ScrollUpDownProc':
Viewport.c:866:15: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
