Use a static README file and the standard Autotools INSTALL

The autogeneration for those files wasn't really adding anything,
and resulted in us fighting with the Autotools.

INSTALL.in

-Simple install procedure
-========================
-
-  % tar xf newport-@NEWPORT_VERSION@.tar.gz # unpack the sources
-  % cd newport-@NEWPORT_VERSION@            # change to the toplevel directory
-  % ./autogen.sh                             			# run the `autogen' script
-  % make                                    			# build newport
-
-  [ Become root if necessary ]
-  % make install                            			# install newport
-
-Requirements
-============
-
-newport-@NEWPORT_VERSION@ requires pkg-config, which is tool for tracking the
-compilation flags needed for libraries. (For each library, a small .pc
-text file is installed in a standard location that contains the
-compilation flags needed for that library along with version number
-information.) Information about pkg-config can be found at:
-
-  http://www.freedesktop.org/software/pkgconfig/
-
-GNU make (http://www.gnu.org/software/make) is also required.
-
-Installation directories
-========================
-
-The location of the installed files is determined by the --prefix
-and --exec-prefix options given to configure.
-
-.pc files for the various libraries are installed in
-$exec_prefix/lib/pkgconfig to provide information when compiling
-other packages that depend on newport. If you set PKG_CONFIG_PATH
-so that it points to this directory, then you can get the
-correct include flags and library flags for compiling a newport
-application with:
-
- pkg-config --cflags newport-@NEWPORT_VERSION@
- pkg-config --libs newport-@NEWPORT_VERSION@
