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.

When integrating the wayland event-loop into another event-loop, we
currently have no chance of checking whether there are pending idle
sources that have to be called. This patch exports the
"dispatch_idle_sources()" call so other event loops can call this before
going to sleep. This is what wl_event_loop_dispatch() currently does so we
simply allow external event-loops to do the same now.
To avoid breaking existing applications, we keep the call to
dispatch_idle_sources() in wl_event_loop_dispatch() for now. However, if
we want we can remove this later and require every application to call
this manually. This needs to be discussed, but the overhead is negligible
so we will probably leave it as it is.
This finally allows to fully integrate the wayland-server API into
existing event-loops without any nasty workarounds.

wl_client_add_resource() used to return no error even though the new
resource wasn't added to the client. This currently makes it very easy to
DOS weston by simply posting thousands of "create_surface" requests with
an invalid ID. Weston simply assumes the wl_client_add_resource() request
succeeds but will never destroy the surface again as the "destroy" signal
is never called (because the surface isn't linked into the wl_map).
This change makes wl_client_add_resource() return the new ID of the added
object and 0 on failure. Servers (like weston) can now correctly
immediately destroy the surface when this call fails instead of leaving
the surface around and producing memory-leaks.
Instead of returning -1 on failure and 0 on success, I made it return the
new ID as this seems more appropriate. We can directly use it when calling
it with new_id==0.

There is really no need to increment "n" if we never read the value. The
do-while() loop overwrites the value before it is read the first time.

This theme is loaded when the specified cursor theme can not be found.
These cursors are extracted from the xorg sources and transformed into
raw ARGB data by a small helper program (commited separately).
This finalizes Robert Bradfords patch to allow NO_ASSERT_LEAK_CHECK
environment variable to disable leak checks in unit tests.

This patch adds a few more directories to search for xcursor themes.
Along with the weston patch, this adds the ability to configure weston
to use an X11 cursor theme. Previously, wayland cursor would just look
in the icons and pixmaps directories for cursor images to load. This
adds the ability to also search in the x cursors directory.
Expose these to other files using wayland-private.h, so wayland-client.c
can walk NULLables properly.

Since glibc dlsym() calls calloc, we get a call to our calloc wrapper as
we try to look up the real calloc implementation. dlsym() will fall back
to a static buffer in case calloc returns NULL, so that's what we'll do.
This is all highly glibc dependent, of course, but the entire malloc
weak symbol wrapper mechanism is, so there's no loss of generality here.
So all our tests don't start failing just because we had the temerity to
use realloc() rather than malloc().

If a new object id arrives ensure that there is an empty array entry
created, otherwise we might get out of sync for new ids if object isn't
created by interface implementation.
Creation of new client resources was silently ignored when
wl_client_add_resource() was used on server side and new object id was out
of range.
An error is now send out to the client in such case.
Also changed error message in wl_client_add_object, since
wl_map_insert_at() returns -1 only at invalid new id.
I've found a bug during wayland exploration - if you make two
drag'n'drops in weston client example, dnd - weston crashes with
segfault. I've tried to investigate it and found a problem.
In function drag_grab_button we first call data_device_end_drag_grab,
which sets seat->drag_data_source to NULL. Then we remove
listener from list only if drag_data_source is not NULL.
So if client will not free wl_data_source and start another drag'n'drop,
after the first one. Then two wl_data_source structures will be
free'd on client exit (let's name them s1 and s2).
next and prev pointer of
wl_data_source.resource.destroy_signal.listener_list in both
wl_data_source structures will be seat->drag_data_source_listener,
but next and prev in seat->drag_data_source_listener.link point
to listener_list in s2.
So if you try to iterate over listener_list in s1
then you get drag_data_source_listener as first item and
(struct wl_listener *)(&s2.resource.destroy_signal.listener_list)
Iteration over that list occurs in
wl_resource_destroy->destroy_resource->wl_signal_emit->wl_signal_emit
and try to call function at address of wl_resource->client, so
weston segfaults there.
- don't leak fd in shm_pool_destroy()
- return NULL from wl_cursor_theme_load() if pool fails
Tha last one fixes a segfault, when shm_pool_create() has failed.

Copy the implementation of os_create_anonymous_file() here from weston,

This makes wl_seat_set_keyboard similar to wl_seat_set_pointer in that
it's a no-op, if you try to set keyboard to NULL when it already is
NULL, instead of refusing to set it to NULL ever.
