When we lose the name because somebody replaced us,
we need to stop thinking of ourselves as the primary
instance, and quit.

While uniqueness is great, sometimes you want to restart
a newer version of the same app. These two flags make that
possible.

We have an enum for this, no need to hardcode numbers.

gio: icons should fallback to non-preferred style appropriately.

Resolve "filesystem::{free,size,used} not set for full FAT fs"

Closes #328

See merge request GNOME/glib!163

Previously, glocalfile.c would not set file system metadata for
the free/used key for file systems which reported 0 free space. This is
because some file systems don’t set that metadata when you call
statfs(), so we can’t reliably report it. However, some do, and they
can legitimately set f_bavail and f_bfree to 0 if the file system is
full.

In order to avoid that, always set the file system metadata unless the
file system is FUSE or ncpfs.

This is a partial revert of commit 0b9f24c1e1: instead of the changes
made in that commit, I think we should maintain a blacklist of file
systems which are known to not correctly report free space.
