	* podcast/rb-podcast-parse.c: (rb_podcast_parse_error_quark),
	(rb_podcast_parse_load_feed):
	* podcast/rb-podcast-parse.h:
	* podcast/test-podcast-parse.c: (main):
	In rb_podcast_parse_load_feed, add a flag indicating that the feed
	already exists, and return a GError indicating what actually went
	wrong when we can't parse it.  If the feed already exists, skip the
	MIME type check, as the user has already confirmed that they want to
	use the feed.

	* lib/rb-marshal.list:
	* podcast/rb-podcast-manager.c: (rb_podcast_manager_class_init),
	(rb_podcast_manager_head_query_cb),
	(rb_podcast_manager_subscribe_feed),
	(rb_podcast_manager_free_parse_result),
	(rb_podcast_manager_parse_complete_cb), (confirm_bad_mime_type),
	(rb_podcast_manager_thread_parse_feed),
	(rb_podcast_manager_update_synctime),
	(rb_podcast_manager_insert_feed),
	(rb_podcast_manager_handle_feed_error):
	* podcast/rb-podcast-manager.h:
	Add two new bits of information when parsing feeds: whether the user
	directly requested the feed be parsed (by adding a new feed, or
	updating a single existing feed), used to decide whether to show error
	dialogs; and whether the feed already exists in the database, which
	controls whether the MIME type check is performed.

	When the MIME type check fails for a new feed, ask the user to confirm
	they want to use the feed anyway, and if they do, set the existing
	feed flag and try again.

	* sources/rb-podcast-source.c: (rb_podcast_source_init),
	(rb_podcast_source_dispose), (rb_podcast_source_constructor),
	(rb_podcast_source_add_feed), (rb_podcast_source_cmd_update_feed),
	(rb_podcast_source_feed_error_cell_data_func),
	(rb_podcast_source_download_process_error_cb),
	(rb_podcast_source_entry_activated_cb),
	(rb_podcast_source_location_added_cb), (impl_add_uri),
	(rb_podcast_source_entry_changed_cb),
	(rb_podcast_source_pixbuf_clicked_cb):
	Add a column that displays the error icon for podcasts that had errors
	last time they were updated.

	The effect of all this is that you don't get error dialogs resulting
	from periodic podcast updates any more.  Instead, the error icon
	indicates which feeds had problems, and provides access to the error
	information.

	Fixes #352493.
