Subject: [PATCH] In the command-line shell, if three or more interrupt signals
 (control-c) are received in a row without a response from sqlite3_interrupt()
 then call exit(1) immediately.  This allows control-C to interrupt the shell
 even if it is stuck in a computation or loop that does not involve the VDBE.
