	Fix #398311 in GIMP until corresponding abstraction has been added
	to GLib:

	* app/base/tile-private.h: Use gint64 instead of off_t. (I assume
	the configury makes sure GIMP is always compiled as
	large-file-aware on Unix with an off_t of at least 64 bits?)

	Introduce wrapper macros LARGE_SEEK() and LARGE_TRUNCATE(). On
	Win32 LARGE_SEEK() calls _lseeki64() in the Microsoft C library,
	and LARGE_TRUNCATE calls a new internal function
	gimp_win32_large_truncate(). On Unix they call lseek() and
	ftruncate().

	* app/base/tile-swap.c: Use gint64 instead of off_t. Use
	LARGE_SEEK() and LARGE_TRUNCATE() instead of lseek() and
	ftruncate().
	(gimp_win32_large_truncate): New function. Calls LARGE_SEEK() and
	SetEndOfFile().

	* app/xcf/xcf-load.c (xcf_swap_func): Use LARGE_SEEK() instead of
	lseek().
