- use -no-undefined flag only for building shared libraries (libxine, plugins)
- plugins LDFLAGS unification
- move -no-undefined into LDFLAGS_NOUNDEFINED
- attributes.m4 fix

In dvd_input.c:file_read(), if the read is not done in a single access, the
buffer pointer doesn't get advanced so that the second read overwrites the
data of the first.

I actually don't remember under which circumstances this could happen, but
the flaw in the code is obvious.

The patch is from NetBSD's pkgsrc, and this patch is attributed to an
"unnamed contributor" in the CVS log.

This requires that many other files include config.h themselves.
Also convert <config.h> to "config.h".

libdvdread uses the file length provided by the UDF fs of the title set IFO
files authoritative. I got a DVD which have parts of this file mapped outside
of the provided file size and according to my memory only the offsets in the
files matters in the standard.

This patch adjusts the internal knowledge of the filesize accordingly and at
least allows mplayer to play the dvd.

(Imported from Debian libdvdread 0.9.7-8)

It changes some "defined (__FreeBSD__)" into "defined (__FreeBSD_kernel__)"
and "__FreeBSD_version" into "__FreeBSD_kernel_version".

The changes are performed on places, where feature of kernel is tested. On
some other places, feature of userland/libc is tested, on them "defined
(__FreeBSD__)" remains.

As proposed, include/configure.h cause __FreeBSD_kernel__ be defined if
__FreeBSD__ is defined.
