[patch,fortran] Allow namelist with internal file (PR 28224)

[Tobias Burnus]

:ADDPATCH fortran:

Hello,

This patch implements read/write of namelists from/to internal
files, which is allowed in Fortran 2003 but not in Fortran 95.

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28224

Bootstrapped and regression tested on x86_64-unknown-linux-gnu (4.3.0
20061026).
