Setting bash shebang for all scripts and making them comform with shellcheck.
archiso/initcpio/{hooks,script}/*:
Setting ash shebang for all scripts and making them comform with shellcheck (for dash, as shellcheck has no ash specific
ruleset). Essentially the ash based scripts should be POSIX compliant as much as possible to have an easier time
writing, debugging and maintaining them.
Ensuring that variables are not treated as options and introducing variable quoting.

Integrating shellcheck for initcpio scripts.

The kernel has an open file handle after setting up the mapping. We can
remove it early to make sure it is gone on shutdown.
This helps to keep the cow_device clean for non-persistent systems where
cow_directory contains a version specific string.

Having files on btrfs subvolumes requires to give mount options. Add
boot params archisoflags= and cow_flags= for this purpose. Boot
parameters could look like this:
... archisodevice=/dev/sdaX archisoflags=subvolume=isos
cow_device=/dev/sdaX cow_flags=subvolume=persist ...

Currently, when booting loopmounted iso file, it is necessary to
specify not only img_dev and img_loop (which should be sufficient),
but also archisolabel or archisodevice. With this patch, archisodevice
is directly populated with the correct loop device, and it is not
necessary to specify the label when booting from loopmounted iso,
which makes for leaner and cleaner grub.cfg.

We received an IP address from DHCP server and configure it statically.
This is required if we continue to use network connectivity to access
the root device (for example via NBD or NFS).
The lease is not updated, though. This can cause trouble in networks
with low lease times. So let's flush the addresses if root filesystem
has been copied to RAM. A dhcp client in main system can handle the
network connectivity then.

Umount detaches the loop device automatically, but let's make it
explicit to be sure. Additionally losetup gives:
losetup: /dev/loop0: detach failed: No such device or address
This is kind of expected, let's silent the error message.

The name is more relevant since the usage is shared for both
dm-snapshot and overlayfs.

This is the first attemp to test overlayfs in archiso.
The current dm-snapshot mode is keep and is enabled by default,
while the new mode is enabled via "-s sfs" to mkarchiso.
No new boot parameters are added, since archiso hooks detects
if the .sfs file is for dm-snapshot (airootfs.img inside)
or for overlayfs.
Persistence is supported in overlayfs mode using the same options
(cowlabel or cowdevice), but warning while in dm-snapshot mode,
only one file is used (airootfs.cow), in overlayfs mode internal
files for workdir/ and upperdir/ are allocated, so you can not use
VFAT or NTFS.
To test this, you need to enable [testing] in pacman.conf from
releng profile and edit build.sh then add "-s sfs" in make_prepare()
Look at:
setarch ${arch} mkarchiso ${verbose} -w "${work_dir}" -D "${install_dir}" prepare
Replace with:
setarch ${arch} mkarchiso ${verbose} -w "${work_dir}" -s sfs -D "${install_dir}" prepare
The build requires just half of space that the build for dm-snapshot,
since there is no ext4 img ;)
Just to remember: there is no space gain in .sfs (just about 2M)
There is at least one thing during boot with machine-id service:

Currently, when booting via HTTP, the airootfs.md5 file is downloaded to
/run/archiso/bootmnt/arch/. However, the checksum file is later assumed
to be located at "/run/archiso/bootmnt/arch/${arch}". Fix the _curl_get
invocation and directly place the file in the right directory.
Fixes a regression introduced in commit 5506e1e ([archiso] Rework
checksum function, 2014-06-28).

Among other things, 0bb94de ([archiso] Drop aitab support, 2014-06-28)
removed the possibility to manually set a specific architecture by using
kernel parameters. This, however, is useful, e.g. when installing Arch
Linux on a device that reports itself as i586 but works fine with the
i686 flavor.

If not set, nothing is changed in current behaviour.
Since dm-snapshot allows to use as "COW" a file with any size,
without caring about the the size of "origin", we can avoid creating a
"COW" file of the same size as the "origin". This is really useful,
when using as cow_device= a filesystem that is VFAT where sparse files
are not supported, so if root-image.fs is 1000M, passing cowfile_size=25%
will create a root-image.cow of 250M instead of 1000M.
