	* app/gimpbrush.c
	* app/gimpbrushpipe.c
	* app/pattern_header.h
	* app/patterns.c: (Hopefully) fixed #8150.

	- If something goes wrong during loading, free the resp. object
	  immediately and close it's FD.
	- When destroying, check each pointer before freeing it.
	- Never use if (!gimp_brush_load_brush() || !pattern_load())
	  but check the return values of both calls separately.
	  (the original code tried to free an already destroyed temp_buf).
	- stuff like below (s/sz_PatternHeader/sizeof(PatternHeader)/g etc.)
