Using the sync operation with list option fails with --sysroot when
signed database files are around. Instead use the query operation, which
uses the local databases of installed pakages only.
The only downside is that we do no longer record the originating
repository.

I see cases where a stale loop device stays around and fills up my
partition as image file is still in use and does not get unlinked.
Explicitly detach loop device on umount to fix that.

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:

Remove unused feature, just to save space
sizeof ext4 image (empty): 4.3M vs 403K (du airootfs.img)

(Anyway filesystem is small, so at first mount is may quickly initialized)

* Better control over what files are touched inside chroot (root-image).
Now: NONE :)
* Two new commands:

+ run: If we want to run some command inside chroot
(mkinitcpio, locale-gen, useradd, etc etc...)
* Renamed command: "created" to "install", says much better what does.

We are currently checksuming all files inside $archisobasedir
(aitab, *sfs, kernel/initramfs and boot/syslinux related files)
this is stored in one file only. Its works good for now,
but I think we only need to checksum only aitab and *.sfs if they are needed.
Currently if you boot a dual-iso in i686, also checksum is done
for *.sfs of x86_64. Not a big issue, this just take a bit more time.
The real issue is when booting via PXE with HTTP/FTP methods,
since they download only aitab and needed *.sfs files,
can not use directly the only one file where checksums are stored.
This patch does:
(1) Do not checksum syslinux related files, anyway you are already reach initramfs stage.
(2) Do not checksum kernel/initramfs files, for the same as (1)
(3) Two checksum.${arch}.md5 for each i686 and x86_64 for only aitab and *.sfs.

-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

The name of the bootloader is syslinux, while isolinux is just one
of many components. isolinux.bin now also accepts syslinux.cfg
as a configuration file name (as do all other loaders).
Thus, rename the isolinux/ folder to syslinux/, and rename
isolinux.cfg to syslinux.cfg. The only occurrence of 'isolinux'
is now the actual loader file 'isolinux.bin'. This makes
the transition from isolinux to the other syslinux loaders
easier when remastering the ISO onto another medium.
Currently works partially since in bash "*" is not expanded.
Old dirs removed, always empty dirs removed from list.
Also cleanup sync databases from pacman 3.4.0, avoiding problems with
pacman -Sy since "sync" directory is deleted.

As in title, this patch cleans up opt flags that exist for no reason and
adds additional flags to modify the disk meta info which would otherwise
be hardcoded.
I wasn't quite sure about the user directory part but it doesn't seem
like a good idea to put that part into the script and therefore I
commented it out. It would probably interfere with rc.local scripts that
take care of skel copying. I replaced the part after the TODO with a
safe guard to make sure that people who are not aware of the changes
will not be caught by surprise.

The current implementation in how partition is created for ext2 img
it looks a bit bad.
This patch makes the partition in more standarized way, respecting
cylinder alignement:
* The size of resulting image will be in cylinder multiple ~8MB.
* Use fdisk instead of sfdisk (sfdisk write some bad information)
* Make the result image in one pass, instead of concatenating.
Also the advantage is that with this can add another partitions
without any issues in the usb-flash-drive with this .img.
