fstools: backport fixes from master branch

The following changes are backported from the master branch

bdcb075 libfstools: fix matching device name
(f038a61 on master)

ef2d438 fstools: use -Wno-format-truncation instead of -Wno-error=format-truncation
(c43ae11 on master)

d361923 build: disable the format-truncation warning error to fix gcc 7 build errors
(a19f2b3 on master)

cddc830 libfstools: silence mkfs.{ext4,f2fs}
(88d48d5 on master)

be5004c libfstools: add basic documentation of mount functions
(92b4c2c on master)

34d36c2 add missing includes
(7d78836 on master)

A previously added hotfix was replaced by a git commit, hence the patch
file is removed and we got instead

45c2a6f libfstools: fix multiple volume_identify usages with the same volume
(633a8d0 on master)

- volume
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-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.
