Mostly this gets rid of the trailing space on line 2 after

Since there is no overlap between the clpreauth and kdcpreauth
interface declarations, there's no particular reason to combine them
into one header.  For backward compatibility and convenience, leave
behind a preauth_plugin.h which includes both.

The upstream libverto depends on dynamic loading and in particular on
dladdr(), which is not universal.  To avoid this dependency, stub out
support for module loading (by replacing module.c) and instead
integrate the k5ev module directly into the bundled verto library.

This change removes the need to link, include, and invoke libverto
differently depending on whether we're using the bundled library; we
can always just link with -lverto and call verto_default().

When we build with the internal verto, we include verto-k5ev.h in
order to create loops.  When we build with the system verto, we don't
include that header file.  Add depfix logic and pre.in variables to
avoid depending on verto-k5ev.h for a system verto build.

When we have conditionally built bundled source, we need logic in
depfix.pl and variables in pre.in to avoid depending on the bundled
verto.h in generated dependencies.  Add that logic for verto.
