MFront: check if the behaviour is small strain or finite strain
Currently, one can use a MFront finite strain behaviour with GDEF_LOG, leading to a severe crash. Whether a MFront behaviour is a finite or small strain behaviour shall be checked by Code_Aster. This piece of information is given by the <behaviour>_BehaviourType symbol exported in the library.
A small strain behaviour shall be usable in HPP, GROT_GDEP and GDEF_LOG. A finite strain behaviour shall only be usable with SIMO_MIEHE. (and with GROT_GDEP for MFront >= 3.1 and Code_Aster >= 14.0 (?))
