David van Moolenbroek 3d697930dd TTY: use libchardriver; clean up ... - writing to a PTY master side blocks if there is not already a blocked reader on the slave side, and select now reflects this; - internally, TTY now uses a test based on "caller != NONE" rather than "grant != GRANT_INVALID" to identify whether a call is currently ongoing; - "offset" fields have been removed as they equal the corresponding "cum" fields; - improved variable typing and function naming here and there; - various other small fixes.
