bc053a975a zdsfs: add online vtoc refresh
Enable zdsfs to access datasets that were created after zdsfs was
mounted without the need to remount zdsfs.
This is done by re-reading the VTOC with every readdir system call.
To ensure a consistent VTOC state the DASD device is reserved for
every VTOC read and released afterwards.

b165500b69 libutil: Add function to print separator line
In wide format the header is separated from the rest of the
records by a separator line. Add support to print such a
separator line also between some records.

Add function util_rec_print_separator() that prints the
separator line for wide format only. For other formats this
is a NOP.

5f2ddad6a8 libutil: Add support for indenting records
Functions rec_print_xxx allows to print records in
different formats. Add support to optionally indent
the output by a specific number of characters.

The indention is set using a new function util_rec_set_indent().
The default indention is zero, thus existing applications
will behave the same as before.

aefc8cd3ff libutil/libu2s: Move strlcpy() implementation to libutils
The strlcpy() implementation in libu2s is beneficial for other tools as
well. Move the implementation to libutils and replace misc_strlcpy() in
libu2s accordingly.

Change the link order in zipl to make it build again.

cd46297d7c s390-tools/utils: handle util_scandir errors correctly
The util_scandir_* functions may return 0 or -1, in which case no vector
is allocated in libutil/util_scandir.c. util_ptr_vec_free, called by
util_scandir_free or directly from lschp.c and lsscm.c, does always
call free for the vector which might be not initialized.

Fix this by always initializing the vector with NULL in __scandir and
add some api hardening by checking the vector and count in
util_ptr_vec_free before iterating over the vector.
And update the comment for util_scandir to indicate that -1 may be
returned in error cases plus that the vector is initialized with NULL.

eaa2ef6ba4 libvmcp: Add common vmcp code to the lib
This patch prevents code duplication in vmcp related programs.
Some applications such as vmur, vmcp, and lsqeth
use z/VM CP commands to query information. Each program
uses its own defines and code.

Supply a library and common header file to use common code.

a060dc22db zdev: Use correct path to vmcp binary
The zdev tools use a hard-coded path to locate the vmcp binary. Since
this path may differ between distributions, the vmcp binary may not be
successfully located in all cases. Fix this by using the BINDIR macro
to determine the correct path. This macro is also used during
installation of the vmcp binary itself.
