Define macros of the preprocessor CPP_IIM, CPP_JJM, CPP_LLM so we can
control the resolution from the compilation command, and automate
compilation for several resolutions.

In module yoethf_m, transform variables into named constants. So we do
not need procedure yoethf any longer.

Bug fix in program test_inter_barxy, missing calls to fyhyp and fxhyp,
and definition of rlatu.

Remove variable iecri of module conf_gcm_m. The files dyn_hist*.nc are
written every time step. We are simplifying the output system, pending
replacement by a whole new system.

Modify possible value of vert_sampling from "param" to
"strato_custom", following LMDZ. Default values of corresponding
namelist variables are now the values used for LMDZ CMIP6.
