Data passed to mount(2) is clipped to PAGE_SIZE if its bigger. Previous
implementation checked if error was returned and then started to append layers
one by one. But if the PAGE_SIZE clipping appeared in between the paths, in the
permission sections or in xino definition the call would not error and
remaining layers would just be skipped(or some other unknown situation).
This also optimizes system calls as it tries to mount as much as possible with
the first mount.

Now that the archive package does not depend on any docker-specific
packages, only those in pkg and vendor, it can be safely moved into pkg.

Some graphdrivers are Differs and type assertions are made
in various places throughout the project. Differ offers some
convenience in generating/applying diffs of filesystem layers
but for most graphdrivers another code path is taken.
This patch brings all of the logic related to filesystem
diffs in one place, and simplifies the implementation of some
common types like Image, Daemon, and Container.

If a graphdriver fails initialization due to ErrNotSupported we ignore
that and keep trying the next. But if some driver has a different
error (for instance if you specified an unknown option for it) we fail
the daemon startup, printing the error, rather than falling back to an
unexected driver (typically vfs) which may not match what you have run
earlier.

This has every container using the docker daemon's pid for the processes
label so it does not work correctly.
