standardize log format, save errno.

don't sign extend character otherwise flsbuf can return EOF falsely

remove signal calls in favor of sigblock/sigsetmask

return the number of symbols not found

I give up; sticky EOF stays.

cure cancer

use malloc instead of static 8K sobuf.

inline expand gtty() and stty().

inline expand gtty (i.e. change gtty to ioctl).
