In addition to generic fd relative porting,
this is a necessary preparatory step for libglnx porting, because
when I tried to use `g_mapped_file_new` I hit an issue with
it using a different error domain from GIO.
Thankfully libglnx consistently uses the GIO error domain, and here
we're now using it for the `open()` call.

Right now though, almost all of the details of deltas are private, so
we can't do the "honest thing" and have the command line just use the
shared library.
Eventually some of this should appear in the API, but for now add
command line which is useful for debugging.
This is a noticeable cleanup, and fixes another big user of GFile* in
performance/security sensitive codepaths.
I'm specifically making this change because the static deltas code was
leaking temporary files, and cleaning that up nicely would be best if
we were fd relative.
For Fedora and potentially other distributions which use globally
distributed mirrors, metalink is a popular solution to redirect
clients to a dynamic set of mirrors.
In order to make metalink work though, it needs *one* file which can
be checksummed. (Well, potentially we could explode all refs into the
metalink.xml, but that would be a lot more invasive, and a bit weird
as we'd end up checksumming the checksum file).
This commit adds a new command:
$ ostree summary -u
To regenerate the summary file. Can only be run by one process at a
time.
After that's done, the metalink can be generated based on it, and the
client fetch code will parse and load it.

This has a very basic level of functionality (deltas can be generated,
and applied offline). There is only some stubbed out pull code to
fetch them via HTTP.
But, better to commit this now and improve it from a known starting
point, rather than have it languish in a branch.
Add an optional dependency on gpgme to add GPG signatures into the
detached metadata, with the key "ostree.gpgsigs", as an "aay", an
array of signatures (treated as binary data).
The commit command gains a --gpg-sign=<key-id> argument. Also add an
argument --gpg-homedir to set the GPG homedir where we look for
keyrings.
We used to have a version of this, but since I'm trying to use
GBytes more, this became a more common operation, and it's annoying
to type out the whole G_VARIANT_TYPE ("ay") each time, and pass
TRUE for trusted.

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.
