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.

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.

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.

Function strstrip strips leading and trailung
spaces from a given string.
During review it was decided to move this function
to the libutil library to make it available for other tools.

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.
