The functions are refactored so the `struct zg_fh` value is now passed as
argument to the `nt_*` functions instead of accessing the global variable `g.fh`
from within of the functions. This makes the functions reusable and easier to
test. While at it, improve the documentation of `nt_read`.

The dracut installation directory is referenced from `chreipl-fcp-mpath`,
`zdev`, and `zipl`; in each with its own individual definition and
variable name. This makes it unnecessarily hard to change it when
installing from the top level directory of s390-tools and passing
variable overwrites via the command line.
Fix this by defining a common `DRACUTDIR` variable in the shared
`common.mak` file, and referencing this in each tool as base directory.
With this a user can simply pass `DRACUTDIR=/foo/bar/baz` on the
commandline and change the installation for all three tools.
Further, also derive common `DRACUTCONFDIR` and `DRACUTMODDIR` variables
from `DRACUTDIR` in `common.mak`, so that `zdev` and `zipl` don't use
different variable names for the same directory anymore, and all these
are defined together in a common place.
Semantically nothing changes for a default build/installation.

UDEVDIR is used in both `chreipl-fcp-mpath` and `zdev`, but with a
different meaning. In the former it points to the base udev directory,
not the rules directory; in the later it points to the rules directory.
If someone was to call `make` from the top level directory, and set
UDEVDIR for the whole build/installation, it would either break `zdev`
or `chreipl-fcp-mpath` (depending on what it was set to).
Fix this by pulling the definition of it in the shared `common.mak`
file, and giving it a common meaning. Point UDEVDIR to the base udev
directory, and UDEVRULESDIR to the rules directory below it.
