When multiple hooks are registred, both pre-a and post-command hooks'
foreach loops need to have a separator at the end in order for the
code to work as intended. Without the separator all hooks end up as a
one single line command thus making all but the first hook into
no-ops.

In case we're using an initrd, we create an empty "root" directory that
will contain only the bootloader stuff, not the actual root filesystem,
because it is in an initrd (standalone or initramfs).
We have to ensure that the directory is empty before assembling the
filesystem (to avoid any file lingering from a previous run, like the
sequence "make; make"). So we first remove it before we create it, so
that on each build (especially not-from-scratch builds) we get the exact
expected content without any leftover.
However, the macro responsible for that, although defined since 7080eef9,
was never called.
Fix that by registering it as a pre-gen hook.
Note: the directory need not be created, as there are quite a few
"install -D" commands that ensure it is created. Yet, we prefer to
create it explicitly to avoid any confusion.

By default, mksquashfs uses all the CPUs available, like us with
BR2_JLEVEL=0.
However, by setting BR21_JLEVEL to non-zero, a user volutarily limits
the number of jobbs allowed to run concurrently (for various reasons,
like this is not a priority task on the machine; or like the
autobuilders, to spread the load accross multiple runs without
overloading the machine).
So, propagate tthe parallelisn settings down to mksquashfs, to repect
the user's will.

In some cases, the directory structure we want in the filesystem is not
exactly what we have in target/
For example, when systemd is used on a read-only rootfs, /var must be a
tmpfs. However, we may have packages that install stuff in there, and
set important rights (via the permission-table). So, at build time, we
need /var to be a symlink to the remanent location (/usr/share/factory)
while at runtime we need /var to be a directory.
One option would have been to have /var as a real directory even during
build time, and in a target-finalize hook, move everything out of there
and into the "factory" location. However, that's not possible because
it's too early: some packages may want to set ownership and/or acces
rights on directories or files in /var, and this is only done in the
fakeroot script, which is called only later during the assembling of the
filesystem images.
Also, there would have been no way to undo the tweak (i.e. we need to
restore the /var symlink so that subsequent builds continue to work) if
it were done as a target-finalize hook.
The only solution is to allow packages to register pre- and post-hooks
that are called right before and right after the rootfs commands are
executed, and inside in the fakeroot script.
We can however not re-use the BR2_ROOTFS_POST_FAKEROOT_SCRIPT feature
either because it is done before the filesystem command, but there is
nothing that is done after. Also, we don't want to add to, and modify a
user-supplied variable.
So, we introduce two new variables that packages can set to add the
commands they need to run to tweak the filesystem right at the last
moment.
Those hooks are not documented on-purpose; they are probably going to
only ever be used by systemd.

mkfs is now capable of generating rootfs images. Use mkfs instead of
genext2fs.
If not set, we now let mkfs calculate the block size and the number of
inodes needed.
This change also adjusts the options to meet those of mkfs.
Notes:
* Passing a null inode number to mkfs triggers its automatic calculation.
* Passing a fs-size with no unit suffix to mkfs is interpreted as using

Currently, when there is no syztem device table (permissions or static

are guarded by the check on the system device tables being non empty.
Fix that by narrowing the guarding condition.
Note that the dependency on host-makedevs was not conditional; we always
build it even if we don't need it. Making it conditional is not
possible, because we don't know all the packages permissions by the time
the fs infra is parsed (packages from br2-external are parsed after it).
