#678 typo in error message (and internal variables)

[Geoffrey Coram]

"unkown" should be "unknown"

osdi/osdicallbacks.c: fprintf(stderr, "OSDI(unkown) %s", handle->name);
osdi/osdiregistry.c: printf("warning(osdi): unkown $limit function \"%s\"", lim_table[i].name);
osdi/osdisetup.c: uint32_t unkown = descr->jacobian_entries[i].nodes.node_2;
osdi/osdisetup.c: unkown = node_mapping[unkown];
osdi/osdisetup.c: double *ptr = SMPmakeElt(matrix, (int)equation, (int)unkown);
osdi/osdisetup.c: uint32_t unkown = descr->jacobian_entries[i].nodes.node_2;
osdi/osdisetup.c: unkown = node_mapping[unkown];
osdi/osdisetup.c: if (equation != 0 && unkown != 0) {
osdi/osdisetup.c: uint32_t unkown = descr->jacobian_entries[i].nodes.node_2;
osdi/osdisetup.c: unkown = node_mapping[unkown];
osdi/osdisetup.c: if (equation != 0 && unkown != 0) {

Also "initalization" should be "initialization"

osdi/osdisetup.c: errMsg = tprintf("%i errors occurred during initalization", info.num_errors);

[Geoffrey Coram]

osdi/osdiinit.c: errMsg = tprintf("Unkown OSDI type %d for parameter %s!",
