Its add support for downloading the ISO image via HTTP/FTP with curl or download *.sfs files.
The files are downloaded on /run/archiso/curlspace (tmpfs) and setup a loop dev from it
(like in archiso_loop_mnt) in the ISO case, or just do a bind mount to
/run/archiso/bootmnt in the other case.
This hook must be located after archiso_pxe_nbd in mkinitcpio.conf, in that way
NBD is the default.
New bootparm:
* archiso_curl_url=(first form)
archiso_curl_url=http://192.168.0.7/archlinux/iso/archlinux.iso (absolute form)
Use an absolute URL. Fetch the entire ISO
archiso_curl_url=ftp://${pxeserver}/archlinux/iso/archlinux.iso (relative form)
Use the as IP the same server where PXE reside. Fetch the entire ISO
* archiso_curl_url=(second form)
archiso_curl_url=http://192.168.0.7/archlinux/iso/unpacked (absolute form)
Use an absolute URL. Where unpacked (an example name) is a directory where
${archisobasedir} ("arch" by default) is located with all *.sfs.
This fetch only needed files.
archiso_curl_url=ftp://${pxeserver}/archlinux/iso/unpacked (relative form)
Use the as IP the same server where PXE reside. Where unpacked (an example name)
is a directory where ${archisobasedir} ("arch" by default)
is located with all *.sfs. This fetch only needed files.
* curlspace_size= Set a size for a tmpfs filesystem where files are downloaded.

One hook only setup the network device (archiso_pxe_common) the other
setup the NBD client (archiso_pxe_nbd).
New bootparam:
archiso_pxe_srv=IP
Allow to set an IP different from the PXE server.

In this way allow to mount /run/archiso/bootmnt from another hook,
but still use the logic from the main mount_hook, skipping only this mount.

* Now bootmnt/img_dev is always a ro-mount,
and cowspace is first ro-mount then rw-mount.
* Fix a "hidden" bug: at the time of test [[ -ef ]], if devices nodes
are not ready, such test will fail then archisodevice will mounted ro and
when cow_device is mounted to be rw it fails.
(I recently suffered this on a machine with slow USB)

Add some options to control where all COW files will be located.
Until this moment all files are located in a tmpfs filesystem.
Now is posible to set a device via a filesystem label or device node
plus a directory, where all these files will be stored.
All dm-snapshot devices will be persistent by default,
but this can be changed if wanted.
Take care, a filesystem that does not support sparse files maybe
is not the best choice for COW files, because they are created with
the same size (is apparent) like the read-only device (the image.fs inside .sfs).
Of course sooner or later, depending on use, these files actually end up
being as big as the read-only device.
KNOW-ISSUE: On shutdown in step "Unmounting Filesystems" will [FAIL],
all filesystem except $cow_device, will be unmounted/remounted-ro.
For this reason this change needs an archiso_shutdown hook, thats
unmount all block devices used by archiso. (Work in progress)

Separate this code from main mount hook, and make it more generic.
_mnt_dev(device, mountpoint, flags) ->
wait for device and mount, launch a shell if something goes wrong.

* These files was added during developement stage of dm-snapshot branch
of archiso. Never was used, sinse archiso works directly with dmsetup
and with device nodes in /dev/mapper/
* Added 11-dm-initramfs.rules to keep dm info about nodes persistent
in udev db across initramfs/real-root.

Default value is "arch". This implies that all device mapper node
for snapshot devices will be for example: arch_root-image.
This helps AIF to hidden these devices from "Device Configuration".

* A block-level approach vs vfs-level.
* No more unofficial (Linux) things.
* More memory is needed.
* Refactor mkarchiso.

* Change from none -> union (looks like util-linux is confused BUG?)
Avoid the message: "umount aufs failed: not found" at shutdown.
#1 mount -t tmpfs none /something
#2 mount -t tmpfs xxxx /something
The output of findmnt -rnu -o SOURCE will be blank in #1.
* Change from aufs -> auto, make its more generic.

Add two parameters:
img_dev=/dev/sdNM
where /dev/sdNM is the device where .iso is located.
img_loop=/path/to/arch.iso
where /path/to/arch.iso is the full path of the .iso in the device img_dev.

-D <install_dir> allow to select install directory on target media
defaults to "arch".
There is a new %INSTALL_DIR% macro for syslinux.cfg.
This is how ISO will look now:
/syslinux only syslinux related files (syslinux.cfg, *.c32, etc)
/arch/ isomounts + *.sqfs images
/arch/boot/ Linux + initramfs + Memtest86+ + other files for early boot stage
