In order to support ISO9660 bootable images that rely on Grub 2, this
commit modifies thr Grub 2 makefile to generate and install an El
Torito image. Such an image is simply produced by concatenating the
cdboot.img provided by Grub 2, and the Grub 2 image generated by
Buildroot using grub-mkimage.
Since this action is so simple and cost-free, we don't bother adding a
Grub 2 sub-option for that, and simply generate the El Torito image
unconditionally.

This commit adds a new option, which allows, when isolinux is used as
the bootloader, to generate an "hybrid" ISO image. Such images can
either be booted from CD-ROM or from USB keys. It simply uses the
isohybrid tool provided by syslinux.

In preparation to the introduction of the support for other
bootloaders than Grub, this commit switches from having the iso9660
support "select" the necessary bootloader to using a "depends on".
The main motivation is that the isolinux bootloader support will
really need to do a "depends on", due to the need of having a certain
option enabled, but this option being a kconfig "choice".

In preparation to the introduction for the support of other
bootloaders than Grub, this commit adds a "choice ... endchoice" block
with just the Grub option, and adds some conditionals in the
iso9660.mk code for the Grub specific parts.
Of course, for now those conditionals are a bit useless with just this
commit, but they become useful with the followup commits.

In preparation to the introduction of the support for other
bootloaders that Grub, this commit introduces two new variables:
- ROOTFS_ISO9660_BOOTLOADER_CONFIG_PATH, which gives the full path to
the bootloader configuration file
- ROOTFS_ISO9660_BOOT_IMAGE, which gives the relative path of the
main bootloader image, as needed by genisoimage's -b option.
There are no functional changes made, as the variables are for now
always set to the same value.

Until now, the iso9660 filesystem handling only supported using an
initrd/initramfs to store the root filesystem, which is very different
from what we do with the other filesystems.
This commit changes the iso9660 logic to also allow using directly an
iso9660 filesystem to store the root filesystem. A new option,
BR2_TARGET_ROOTFS_ISO9660_INITRD, is created to tell the iso9660 that
we want to use an initrd and not directly the root filesystem in
iso9660 format. This option defaults to 'y' to preserve the existing
behavior.
After this commit, we therefore have three possibilities:
* BR2_TARGET_ROOTFS_ISO9660=y, with BR2_TARGET_ROOTFS_INITRAMFS and
BR2_TARGET_ROOTFS_ISO9660_INITRD disabled. In this case, the
iso9660 filesystem is directly the contents of the root filesystem
(since is possible thanks to the Rockridge extensions that were
already enabled using the -R option of genisoimage). Obviously, it
means that the root filesystem is read-only.
* BR2_TARGET_ROOTFS_ISO9660=y and BR2_TARGET_ROOTFS_INITRAMFS=y (the
value of BR2_TARGET_ROOTFS_ISO9660_INITRD doesn't matter). In this
case, the root filesystem is already linked into the kernel image
itself, as an initramfs. So the iso9660 filesystem doesn't contain
the root filesystem as is, but just the bootloader and the kernel
image.
* BR2_TARGET_ROOTFS_ISO9660=y, BR2_TARGET_ROOTFS_ISO9660_INITRD=y and
BR2_TARGET_ROOTFS_INITRAMFS disabled. In this case, a separate
initrd is used. The iso9660 filesystem only contains the
bootloader, the kernel and the initrd.
In order to support the first case out of the box, root=/dev/sr0 is
added on the kernel command line in the example Grub configuration
file, so that the kernel knows where the root filesystem is
located. This argument is ignored when initrd/initramfs are used.

The iso9660.mk modifies the menu.lst file from Grub to set the correct
initrd/kernel image locations. However, with the upcoming support of
other bootloaders for iso9660 filesystems, we need to modify a bit
this logic.
Instead of relying on the specific details of the grub menu.lst
syntax, we introduce the __KERNEL_PATH__ and __INITRD_PATH__ magic
keywords, which iso9660.mk will replace by the appropriate
values. They can therefore be used where needed in grub menu.lst, and
in similar configuration files of other bootloaders, as will be
supported in the following commits.
Also, in order to be consistent with the soon to be introduced support
for having the root filesystem itself as iso9660, this commit changes
the installation location of the initrd and kernel. Instead of being
/initrd and /kernel, they become /boot/initrd and
/boot/$(LINUX_IMAGE_NAME).

Instead of using directly the splash image from the Buildroot source
directory boot/grub, this commit changes the iso9660 logic to use the
splash image installed in $(TARGET_DIR)/boot/grub.
This effectively allows a user to use a custom splash image by
installing it to $(TARGET_DIR) through a rootfs overlay or using a
post-build script.

as the real root filesystem, this commit changes the location of the

used, the splash image is installed at the same location.

This commit converts the iso9660 logic to the common rootfs
infrastructure. What previously prevented it from being converted is
that the iso9660 logic needed to remove a temporary folder after the
image has been created.
However, since Buildroot typically keeps build artefacts around, this
commit changes the logic to keep this temporary folder around. Thanks
to this change, converting to the common rootfs infrastructure becomes
possible.
In addition, the temporary folder is renamed from $(BUILD_DIR)/iso9660
to the more descriptive $(BUILD_DIR)/rootfs-iso9660.tmp.

Since we now have uClibc-ng, and it is used as the default uClibc
version, there is no real need to keep the Xtensa version: this
version is just a specific Git revision of uClibc master branch, and
uClibc-ng is also based on uClibc master branch.
In addition, since in the choice of uClibc versions, uClibc-ng is
already *before* the Xtensa specific version, uClibc-ng has in fact
already been the default uClibc version for Xtensa since uClibc-ng
support was introduced.
See for example:
http://autobuild.buildroot.org/results/c85/c854fae31d82e0f11d5a8b5bfc196c29bd7e21db/config
for a build on Xtensa with the internal toolchain, where in fact
uClibc-ng is used instead of the Xtensa specific version.
