state: use packed attribute for on storage structs ...

These structs are used for on-storage data layouts. They should be not
affected by different integer precisions and alignment optimizations of
32bit or 64bit machines. Using the architecture independent integer data
types, like uint32_t, achieves the former, using the packed attribute
the later.

Add filetype and detection for squashfs images ...

This adds `filetype_squashfs` to the list of known filetypes and adds a
detection for squashfs files to file_detect_type(). This currently
matches on the `hsqs` start sequence of an image file.

Additionally, the newly introduced filetype is registered as the type of
the squashfs_driver which allows, for example, to mount squashfs without
the need to specify a type parameter.

This changes enable booting a squashfs with the simple `boot` command
pointing to the location (device) that holds the squashfs.

Note that booting with blspec is limited as the current squashfs driver
is not capable of handling symbolic links.

Allow device parameters for devices with dots in name ...

Devices can have a dot in the name, so we can't expect to find the
full device name before the first dot. Currently parameters of devices
with a dot in the name are inaccessible from the shell.
Fix this by iterating over the possible device name / parameter name
combinations to find a existing combination.

Subject: [PATCH 1/1] environment: "wrong magic" give the impression of an
 error

Introduce a more soft wording when the magic of
the superblock does not match.
Include a hint to the typical reason "(envfs never written?)"

This prevents a "what is wrong?" moment when looking at
the boot log.

boot: add framework for redundant boot scenarios ...

There are several use cases where a redundant Linux system is needed. The
barebox bootchooser framework provides the building blocks to model different
use cases without the need to start from the scratch over and over again.

The bootchooser works on abstract boot targets, each with a set of properties
and implements an algorithm which selects the highest priority target to boot.

See the documentation contained in this patch for more information.

globalvar: Also create globalvars from for nonvolatile device vars ...

nv variables beginning with "nv.dev.<devname>.<varname>" are directly
mirrored to <devname>.<varname> and there is no globalvar for it. To
make it a bit more consistent and to increase the visibility of the
nonvolatile device variables create globalvars for them aswell.

With this the propagation flow has changed from:

nv.dev.<devname>.<varname>
  -> <devname>.<varname>

to:

nv.dev.<devname>.<varname>
  -> global.dev.<devname>.<varname>
    -> <devname>.<varname>
