Added NetBSD support to libpciaccess.

While fixing this, I had to make autoconf, automake and m4
templates (latest versions).

xorg-server-1.5.1 now fully works on NetBSD with these patches!

+ Autoconf is an extensible package of m4 macros that produce shell

+ These scripts can adapt the packages to many kinds of UNIX-like
+ systems without manual user intervention.  Autoconf creates a
+ configuration script for a package from a template file that lists the
+ operating system features that the package can use, in the form of m4
+ macro calls."
