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.

libblkid-tiny: add btrfs probe info
This only adds the magic for btrfs to show btrfs volumes in
block detect.
In order to properly support btrfs with more than one device and avoid
trying to mount the same device group once for each instance we have to
make sure that only one device per group will be mounted (btrfs then
automatically detects all other devices of the group).
For unmounting, the opposite should be applied: umount if called for
any of the devices in a mounted device group, unmount the filesystem.

libfstools: ubi: rework reading volumes
UBI volume IDs don't have to be contiguous, this may happen if there
were few and the not last one was removed. In such case we may have
e.g. ubi0_0, ubi0_2.
It means we can't simply read value from "volumes_count" and iterate
from 0 to the count - 1.
This patch rewrites ubi_part_match to read whole directory and look
for ubi%d_%d entries in it.
