 1.13 26-Jul-2020  mlelstv Refactor remaining mount_* commands to use the common pathadj()
function for resolving paths.

Make pathadj() no longer warn about symlinks. Symlinks in /dev are
regularly used in several places like LVM . The warning was also
only visible when calling a mount_* command directly as mount(8)
itself would resolve the path witout warning before passing it to
a mount_* command.

 1.21 26-Jul-2020  mlelstv Refactor remaining mount_* commands to use the common pathadj()

only visible when calling a mount_* command directly as mount(8)
itself would resolve the path witout warning before passing it to
a mount_* command.
 1.20 25-Jul-2016  erh Eliminate the distinct path check, since the paths don't actually need to be
distinct and allowing this makes certain useful tasks possible, such as
fixing an unpopulated /dev while a tmpfs is mounted over it.
However, require the paths to be different, as mounting a path directly over
itself has the side effect of causing any other mount points within that path
to no longer be accessible, and is difficult to unmount when done on /.
 1.19 29-Aug-2011  joerg branches: 1.19.24;
Use __dead
 1.18 20-Jul-2008  lukem Remove the \n and tabs from the __COPYRIGHT() strings.

 1.17 16-Jul-2007  pooka branches: 1.17.12; 1.17.16;
Make all mount(2) return value error checks against -1. Some file
systems just checked != 0, breaking MNT_GETARGS. Others worked with < 0,
but make them check against -1 too for consistency. And sprinkle some
stylish line wrapping where appropriate.
 1.16 14-Jul-2007  dsl Add additional 'sizeof args' parameter to mount(2).
 1.15 16-Oct-2006  christos use MOPT_NULL

 1.9 21-Sep-2002  christos MNT_GETARGS support
 1.8 30-Oct-2000  jdolecek make the code includable into other programs:

MOUNT_NOMAIN is not defined

versions removed
