Subject: Fix races in scstart().  q_to_b() wasn't called at spltty(), so there
 were two races: - q_to_b() might unexpectedly return 0 (e.g, after a keyboard
 signal   flushes the output queue and isn't echoed).  ansi_put() interprets  
 0 bytes as 4GB... - more output (e.g. for echoes) might arrive afer q_to_b()
 returns 0.   Then scstart() returns presumably and the new output might not
 be   handled for a long time.

Remove unused function scxint().

Fix prototypes (foo() isn't a prototype).
