Bug 568394 – dropping the last reference to a stream filter closes the
base stream
* gfilterinputstream.h:
* gfilterinputstream.c: add "close-base-stream" property and only
close the base stream if it is true. issue async close callbacks from
correct source object.
* gfilteroutputstream.h:
* gfilteroutputstream.c: add a "close-base-stream" property and only
close the base stream if it is true. issue async close callbacks from
correct source object.
* gbufferedoutputstream: check g_filter_output_stream_get_close_base()
before closing the base stream. fix invalid source tag comparison in
close_async (was comparing to flush_async).
* ../docs/reference/gio/gio-sections.txt:
* gio.symbols: add
g_filter_{in,out}put_stream_{g,s}et_close_base_stream
* tests/filter-streams.c: new test cases
* tests/Makefile.am: add new test
* tests/.gitignore: add new test
