Lots and lots of preparation led to this moment - when nothing
apparent changes for users! Woo!
But seriously, having the extra dependency is a minor annoyance, and
in the big picture I think the libgsystem idea was wrong - we need to
land things in GLib, and use git submodules for API-unstable or
Linux-specific sharing. For a lot of OSTree, the libgsystem `GFile*`
orientation was also wrong, we really want fd-relative.

Import `gs_file_enumerator_iterate()` for the next six months or
so...after RHEL 7.3 is released I'm strongly considering hard
requiring 2.46 or so.
Likely at some point we should figure out how to share more "glib
backport" code with NetworkManager at least.

There might be a race here in that we create new symlink files *after*
calling `syncfs`, and they are not guaranteed to end up on disk.
Rework the code so that we create symlinks before, and then only
rename them after (and `fsync()` the directory for good measure).

This still needs verification that we're fixing a real bug; but I'm
fairly confident this won't make the fsync situation worse.
https://bugzilla.gnome.org/show_bug.cgi?id=755595
To be really sure that any directory entries have hit disk we need to
call fsync() on the directory fd. This API allows us to conveniently
create a directory hierarchy, fsyncing all of it along the way.
Let's be a bit more conservative here and actually fdatasync() the
configurations we're generating.
I'm seeing an issue at the moment where syslinux isn't finding the
config sometimes, and while I don't think this is the issue, let's try
it.
The qemu helper really wants to copy kernel modules, but not
update the system bootloader. Allow it to reuse ostadmin for
this.
Note that our previous path of shelling out to "cp -al" broke because
it refused to make cross-device links.

Having the archived vs not distinction in the object system wasn't
useful in light of pack files. In fact, we should probably move
towards generating a pack file per commit by default.
Don't expose GChecksum in APIs. Add a new stream class which allows
us to pass an input stream somewhere, but gather a checksum as it's
read.
Move some bits of the internals towards binary csums.
This moves us closer to consistently passing around a triple of:
(GFileInfo *info, GVariant *xattrs, GInputStream *content)
Which will help the libarchive work.
