At some point, the udev was modified to source the functions from
initscripts or lsbinitscripts. This dependency is actually not needed.
If we use udev in a system where initscripts from oe-core is not available,
there will be errors.
This patch fixes this problem by removing the implicit dependency.

In case of a read-only rootfs, we skip the process of generating
udev cache, as the data cannot be persisted between reboots.
However, it's possbile that the $DEVCACHE (default to /etc/dev.tar)
exists in a read-only rootfs, no matter how it's generated or installed.
In such situation, we try to use $DEVCACHE if possible.
Besides the basic changes in the logic of udev cache handling,
this patch also adds code to output more information if the udev
cache is not used and VERBOSE enabled.
This patch also changes the readfile function to readfiles function
so that it could handle more than one file at once.

Fix for bug: https://bugzilla.yoctoproject.org/show_bug.cgi?id=4632
Since udev 172, the 'mknod' logic was removed from udev. Yocto Dylan
is now using udev 182. This means /dev is now required to be a
devtmpfs filesystem (maintained by the kernel). If the root
filesystem is a ramdisk, the kernel's auto-mount of /dev doesn't
activate since there is no rootfs to actually mount... The bug causes
an unusable system as /dev doesn't contain even basic nodes required
to even get a login prompt.
The Yocto udev/init script mounts tmpfs if it does not detect tmpfs
or devtmpfs mounted at /dev. This appears to be outdated logic that
is no longer correct. I believe the Yocto udev init script should be
checking and mounting only 'devtmpfs' on dev.

Previouly, the udev-cache has no real effect even if it's installed
into the system. The key problem here is that at first boot, the
/etc/dev.tar is not present, thus resulting /dev/shm/udev.cache not
created on first boot even if udev-cache is enabled.
This patch fixes this problem. The /dev/shm/udev.cache will be created
if necessary, that is, on first boot or when some part of the system is
changed. In the latter case, the udev cache may not be valid.

Previously in udev init, /var/volatile/run had to be created after
mounting all tmpfs filesystems so that udevd can write to /var/run
(a symbolic link to /var/volatile/run). This is because udev is
started before populate-volatile.sh.
Now that /var/run is a symbolic link to /run (a tmpfs filesystem),
/var/volatile/run doesn't need to be created anymore.

If it's not first boot, /tmp has already been symlinked to /var/volatile/tmp.
But the udev service starts before populate-volatile.sh starts. This leads to
a dead link at /tmp. As a result, trying to create any file under /tmp will
fail.
If a USB is plugged in before the populate-volatile.sh script starts, the
/tmp/.automount-$name file will not be created correctly. As a result, when
the USB is unplugged, the /media/$name directory is not removed.
So we create /var/volatile/tmp directory in the udev script to avoid this dead
link problem.

This is needed because the udev_182 now requires devtmpfs and will not work correctly
with out, so ensure that the kernel contains devtmpfs by checking /proc/filesystems.

Since commit commit fbec192f6bc4 ("udev: Ensure tmpfs are mounted and
volatile/run exists") all tmpfs-entries in fstab are mounted before udev
starts using mount -a. If /dev/shm is among those entries, that mount
will fail as the mount point has not yet been created:
Starting udev
mount: mounting tmpfs on /dev/shm failed: No such file or directory
udevd[474]: starting version 182
Fix by restoring the old way of mounting /dev and mounting the
remaining tmpfs-entries only after /dev/shm has been created.
Also make sure that any errors are supressed for these tmpfs-mounts.
Should any mount point not yet be present, that mount will be retried
later during the boot process.

There is a race with udev where eiher the run directory can get replaced
during bootup leading to ude errors, or if the tmpfs was mounted and
populate-volatiles hasn't run, udev won't start at all.
This ensures that any tmpfs get mounted before udev starts and that the
default volatiles/run directory at least exists, fixing the races
and boot time errors caused after the recent udev upgrade.

This is the final upgrade of udev. Futher upgrades will only
come in conjunction with systemd.
The v4l1 removal patch is deprecated as the bug is fixed inside udev.
There is a new patch fixing the path for default sh interpreter.
New debug binaries are generated, and udev.inc is modified to package
those correctly.
The install locations changed for udevd and udevadm, so the scripts
are updated accordingly.
