* somsolib.c (som_solib_add): Validate regexp argument. 

Don't assume the first entry on dld's library list is the main
        program.  Don't load the same library more than once and don't
        consider the main program a shared library.
        (som_solib_sharedlibrary_command): New function
        (_initialize_som_solib): Add "sharedlibrary" command.
