Added first cut at code to put metafiles in the user's home directory if
* libnautilus/nautilus-directory.c: (nautilus_directory_read_metafile): (nautilus_directory_try_to_read_metafile): (nautilus_directory_write_metafile): (nautilus_directory_try_to_write_metafile): (nautilus_directory_switch_to_alternate_metafile_uri): (nautilus_directory_escape_slashes): (nautilus_make_directory_and_parents): Added first cut at code to put metafiles in the user's home directory if the directory is not accessible and you can't read and write a metafile in the directory itself. We'll have to refine this later to handle cases where you end up with two metafiles. * libnautilus/Makefile.am: libnautilus/nautilus-debug.h: libnautilus/nautilus-debug.c: Took trick for getting into the debugger and put it into a public header file so it can be used outside of the nautilus executable. * src/ntl-main.c: (stop_in_debugger): (nautilus_stop_after_default_log_handler): (main): Use the new calls from libnautilus to set up the drop into debugger for criticals and warnings. * src/file-manager/fm-main.c: (main): Minimized includes and used the new calls from libnautilus to set up the drop into debugger for criticals and warnings. * src/ntl-uri-map.c: (nautilus_navinfo_add_mapping): src/ntl-window.c: (nautilus_window_constructed): src/file-manager/fm-directory-view.c: (fm_directory_view_initialize): (fm_directory_view_destroy): (notify_location_change_cb): (stop_location_change_cb): (fm_directory_view_sort): Removed some messages that aren't so useful. * libnautilus/ntl-view-frame.h: Minimized includes. * libnautilus/ntl-view-frame.c: Include "ntl-view-frame.h" first so it tests to see that it has sufficient includes in it. * src/ntl-view.c: (nautilus_view_load_client): Changed function so that NULL for an iid is allowed and simply results in a failed load instead of being illegal. * src/ntl-window-msgs.c: (nautilus_window_change_location_internal): src/ntl-window.c: (nautilus_window_up): Got rid of calls to gnome_vfs_uri_destroy; use gnome_vfs_uri_unref instead since it's safer and Federico is getting rid of gnome_vfs_uri_destroy. * src/file-manager/fm-directory-view-icons.h: src/file-manager/fm-directory-view-icons.c: (fm_directory_view_icons_new): src/file-manager/fm-directory-view-list.h: src/file-manager/fm-directory-view-list.c: (fm_directory_view_list_new): src/file-manager/fm-directory-view.h: src/file-manager/fm-directory-view.c: (fm_directory_view_new): Minimized includes and got rid of the unused _new functions. * libnautilus/nautilus-directory.h: Added a missing 2000 copyright date.
