Changeset 1521 for trunk/LMDZ.VENUS/libf

All GCMs: Updates to make planetary codes (+Earth) setups converge.

• Made a "phy_common" directory in libf, to contain routines common (wrt structural nature of underlying code/grid) to all LMDZ-related physics packages.
• moved all "mod_phys_*" and "mod_grid_phy_lmdz" files from dynlonlat_phylonlat to "phy_common"
• moved "ioipsl_getincom_p.F90 from "misc" to "phy_common" and modified it to match Earth GCM version and renamed it ioipsl_getin_p_mod.F90
• added an "abort_physics" (as in Earth GCM) in "phy_common"
• added a "print_control_mod.F90 (as in Earth GCM) in phy_common
• made similar changes in LMDZ.GENERIC and LMDZ.MARS
