Bug 536252 – GFileEnumerator should allow access to the containing GFile

Browse Source 
2008-06-16  Ross Burton  <ross@burtonini.com>

	Bug 536252 – GFileEnumerator should allow access to the containing
	GFile
	
	* gio/gfileenumerator.c:
	* gio/gfileenumerator.h:
	* gio/gfile.h:
	Add g_file_enumerator_get_container() and a container writeable
	construct-only property.  Also shuffle around typedefs to make it
	compile.
	
	* gio/glocalfileenumerator.c:
	* gio/glocalfileenumerator.h:
	* gio/glocalfile.c:
	Instead of a string filename take a GFile in the constructor and
	use it to set the container property.
	
	* gio/gio.symbols:
	* docs/reference/gio/gio-sections.txt:
	Update with new API.
