[R] Split RPMS for Fedora Core 3

[Martyn Plummer]

I have split up the R RPMS for Fedora Core 3 into two subpackages - "R"
and "R-devel".  Following the usual RPM naming convention, the basic "R"
package is now for users, and "R-devel" package is for people wishing to
do program development with R.  **** This includes installing R packages
from source ****

Note that R-devel is not the development version of R, but contains the
files needed for creating R packages.

If you have configured up2date to automatically notify you of R updates
on CRAN, then you will need to manually install R-devel to maintain the
same level of functionality.

At the same time, I have created a separate libRmath-devel package,
which provides the Rmath.h header file and a static version of
standalone Mathlib.

This is an experiment, so please let me know if there are any problems.
