Revision 350

Add argument `itau_phy_redem` to phyredem0

Add argument `itau_phy_redem` to phyredem0. Motivation: being able to
call phyredem0 with `itau_phy_redem` = 0 in program ce0l, avoiding the
side effect on nday. We can now add attribute protected to variable
nday of module `conf_gcm`. And we do not need to set `itau_phy` to 0
in procedure `phyetat0_new`.

Remove variable `prt_level` of module `conf_gcm`, which was only used
in procedure advnx. Motivation: cluttering the output is not viable,
even for debug. Better use a debugger.

Forgot to add `dyn3d/ADVN/CMakeLists.txt` in previous revision.
