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).

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)

purge_single command can be usefull to save space during build. It removes
all files in working directory except "iso/" and *.iso.
Workflow can be:
(32) ./build.sh all_iso_single -> i686 *.iso are ready.
(32) ./build.sh purge_single -> safe cleanup.
(64) ./build.sh all_iso_single -> x86_64 *.iso are ready.
(64) ./build.sh purge_single -> safe cleanup.
(any) ./build.sh all_iso_dual -> dual *.iso are ready.

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".

* Use device mapper + snapshot module, instead union layer filesystem.
* A block-level approach vs vfs-level.
* No more unofficial (Linux) things.
* More memory is needed.
* Refactor mkarchiso.
* Refactor hooks/archiso.
* Fix install/archiso_pxe_nbd
(due recent change in mkinitcpio-0.6.15 on checked_modules()/all_modules())
[Thanks Dave for the improved workaround]
* New configs/releng to build official images.
* Works with a Bash script instead of Makefile.
(better control and easy to maintain)
* Remove configs/syslinux-iso.
* Remove archiso2dual script. Integrate functionality in configs/releng.
* New configs/baseline to build the most basic live medium or use as template.
* New README (draft). [Thanks Dieter for fixing english grammar]
