If the root is specified (FIXED-ROOT) by set type or set parent, change ie.mesh_type to MESH_ROOT before connect to router
Release emesh_recv_toDS when the root becomes non-root
esp_mesh_set_type now supports MESH_IDLE and MESH_STA
esp_err_t provided by esp_err.h and thus is required and not optional.
While the python script adds the header, it wraps it with an __has_include
directive that is not supported on all compilers (notably GCC 4.8).
