Summary: provide close() function

Initial Comment:
Pd's API provides several functions to open a a file (e.g. canvas_open() or open_via_path()), but none to close the returned filehandle.

this is usually not a problem, since  an external could call "close()" itself.
unfortunately it doesn't work so well on some platforms that do not handle opening/closing resources across dll-boundaries so well.
(on w32 you can link against a ton of debug/non-debug/threaded/non-threaded/... versions of stdc; and they are usually not compatible)

the solution is (hopefully) to supply a function the close()s a rsesource in the same context as it was open()ed.

the attached patch (against todays svn trunk) adds a "int sys_close(int fd)" that merely wraps the "int close(int fd)" call.
