Coda File System

[PATCH]: Fix overruns in codasrv main routine

Hey, glibc just found this on fedora.  A stack overrun of a few bytes in the
sname variable in the coda server main routine.  Its 20 bytes long, and at least
one of the sprintfs writes at least 23 bytes to the buffer.  The patch below
fixes it.  I suppose switching to snprintf would be better, but the code seems
so unlikely to change further at this point, this just seemed a bit more
