Supports loading of binary blobs which are the result of a extraction of the text section of a shared libraries.
Certain restrictions apply to what you can do and what not in a sahred library to allow it to be converted into a module.

int init_module( /*out*/module_t * mod, const char * modulename )
Maps a file as binary executable into memory whose filename is modulename. The binary must be stored in a directory whose name is configured in resource/config/modulevalues with module=”module_t” and name=”DIRECTORY*. The binary is mapped as is. No relocation is done and no data segments are supproted.
