overlay: fix race condition when switching to jffs2
There is a race between `cp -a /tmp/root/* /rom/overlay` from
libfstools/overlay.c and a process creating new file(s) before
pivot(/rom, /mnt) occured.
That is a process can create a file and it will not be copied.
To workaround this, do additional copy after jffs2 is ready.
This doesn't completely solve the problem but since there
was no other fix provided since original RFC [1], it is better
than nothiing.

libfstools: fix multiple volume_identify usages with the same volume
This fixes e.g. factory-flashed startup issue with jffs2 on ubi overlay
Commit
ba019965 ("libfstools: accept volume as argument in most calls")
broke startup for factory-flashed jffs2 on ubi systems, causing substantial
slowdown in factory environments.
When starting up with a factory-flashed jffs2 on ubi system, the "rootfs_data"
volume contains a deadcode marker. In the start phase, mount_root then mounts a
tmpfs overlay, and postpones remounting of the jffs2 overlay until the done
phase of the startup.
The refactoring in
ba019965 eliminated an unneeded call to volume_find() when
done() called jffs2_switch(). Unfortunately the refactoring did not take into
account that volume_identify() does not function correctly when called twice in
a row on the same struct volume when using an mtd driver.
mtd_volume_identify() uses mtd_volume_load() to open an fd to the mtd device
and reads a potential deadcode marker from the fd. The first time this works,
and FS_DEADCODE is returned.
When volume_identify() is called a second time however, mtd_volume_load()
notices that we already have an open fd, does nothing further and returns 0
without resetting the file offset to 0. mtd_volume_identify() now reads past
the deadcode marker and now returns FS_JFFS2 if the mtd device is a UBIVOLUME.
jffs2_switch() then handles the wrong case, either pulling the root out from
under user-space in Chaos Calmer, or indefinitely sticking to a tmpfs overlay
in later OpenWRT builds.

jffs2reset: use jffs2_mark if rootfs_data isn't mounted
Erasing all rootfs_data blocks may cause some problems with partition
identification. It won't contain MAGIC, but will be successfully mounted
with delayed blocks marking. This may be really confusing when user
reboots before JFFS2 finishes its blocks management. During the next
boot rootfs_data will be a valid partition (possibly with data) but
libblkid won't detect it.
Also adjust message in jffs2_mark to make more sense when used together
with jffs2_reset.
