Although defaulting to wayland-0 seems convenient, it has an undesirable
side effect: clients may unintentionally connect to the wrong compositor.
Generally, it's safer to fail instead. Here's a real example:
In Fedora 22, Gtk+ prefers Wayland over X11, though the default session is still
a normal X11 Gnome session. When you launch a Gtk+ app, it will try Wayland,
fail, then try X11, and succesfully start up. That works fine.
Now suppose you launch Weston while running the Gnome session. Suddenly, all
of the Gtk+ apps launched from Gnome will show up inside Weston instead.
That's unexpected. There's also no good way to prevent that from happening
(other than perhaps setting WAYLAND_DISPLAY to an invalid value when launching
an app).
Not using wayland-0 as the default will solve that problem: an app launched
from the X11 Gnome session will use the X11 backend regardless of whether
there's a wayland compositor running at the same time.
Everything else should work as before. The compositor already sets
the WAYLAND_DISPLAY when starting the session, so the lack of the default value
should not make a difference to the user.

Instead of relying on downloading the stylesheet from the Internet for
generating man pages, only generate them if the stylesheet is available
locally.

We really shouldn't add the man-pages when HAVE_XSLTPROC is not true so
move it into the if-clause.
But declare the automake-variables outside of the if-clause to avoid
automake complaints.

This adds a man-page infrastructure based on Docbook XML files. This
allows us to integrate the man-pages into the publican books later. An
example page for wl_display_connect() (with an alias
wl_display_connect_to_fd()) is also added.
Feel free to add more man-pages. Function calls are put in man3 and
overview pages into man7. All pages (including aliases) have to be added
to the Makefile.
Docbook does generate aliases automatically from the additional names that
were put in the XML file. However, a small SED script is needed to fixup
the include-paths in the generated troff files. If someone knows how to
avoid that (or even install them gzip'ped), please fix it up.
