Seperate pft dependent parameters into a new orchidee_pft.def

[jgipsl]

Step 1 : Separate pft dependent parameters into a new orchidee_pft.def depending on the number of the PFTs instead of keeping all parameters and flags in run.def. To be done in the MAKE_RUN_DEF scripts.

Step 2 proposition for the trunk: Rename run.def in offline configuration to orchidee.def and create run.def which will include variables for the driver and include the files orchidee.def and orchidee_pft.def. This would make better the coherence between offline and coupled configurations.

[jgipsl]

I've tested in offline and coupled mode if the used_run.def/used_orchidee.def/used_orchidee_pft.def are correctly written. Result: is working as it should.

Comment: A parameter set in orchidee_pft.def will be added to used_orchidee_pft.def in the same way as if it was set in run.def, it will be written in used_run.def.
For both cases, only parameters were the getin has been done, will be written. This means that for a type mistake in the parameter name or if the getin is not done in the code, for example if it is under condition of another parameter, then the parameter will not be written in the used_ file.

The default experiments in config/ORCHIDEE_OL have been adjusted to the use of a run.def (driver information), an orchidee.def (model settings) and an orchidee_pft.def (pft parameter values).

TESTSTOMATE -> removed. Will be added back once TESTSTOMATE has been restored.
FORCESOIL -> removed. Will be added back once TESTSTOMATE has been restored.

SPINUP_ANALYTIC_FG1 -> tested -> OK
OOL_SEC_STO_FG1trans -> tested -> OK
OOL_SEC_STO_FG2 -> tested -> OK
OOL_SEC_STO_FG3 -> tested -> OK
OOL_SEC_STO_FG4 -> tested -> OK
OOL_SEC_STO_FG5 -> tested -> OK

OOL_SEC -> adjusted, waiting for a LAI map to be tested. A new LAI map will have to be produced to account for the change in dimenstions.
OOL_SEC_STO_FG3nd -> adjusted, waiting for the new driver to be tested in CN-CAN.

ENSEMBLE -> moved to ticket #637

Several revisions have been committed see config/ORCHIDEE_OL r6303 to r6441
