BDY MPP issues

Description

Merge of trunk rev 4056 and time splitting updates in NEMOGCM/branches/2013/dev_r3867_MERCATOR1_DYN : 3970|3 months|cbricaud: Time splitting update, see ticket #1079

My config:

 bld::tool::fppkeys key_mpp_mpi key_vectopt_loop key_ec01 key_bdy key_dynspg_ts key_ldfslp key_traldf_c3d key_dynldf_c3d key_traldf_smag key_dynldf_smag key_zdftke key_lim2

Where key_ec01 is my domain definition.

BDY has MPP issues which have two manifestations.
1) Model crashes/hangs when using a single(non-tiled) restart file.
2) Model crashes/hangs when using land suppression

Whether the model crashes or hangs depends on whether I include LIM2

With LIM2 both 1) and 2) result in a crash. In this case the ocean.output ends with:

 ...
 lim_sbc_init_2 : LIM-2 sea-ice - surface boundary condition

                 EVP rheology - C-grid case

       between two extremes values (Pyane, 1972)           rn_alphc  =
  0.650000000000000 

and the OPA.ERROR file starts with a strange namelist error:

Without LIM2 case 1) and 2) cause the model to hang. The model appears to hang during bdy_init. The last line in ocean.ouput is:

 bdy_init : initialization of open boundaries
 ~~~~~~~~ 

When compiled without BDY the model runs for both 1) and 2).
