Review Request: Upgrade TerminalInterface to V2 and add two more functions that needed by dolphin. 1. Apps can query if a sub process is running in terminal. 2. Apps can query if there is any input text on command prompt that waits for a RETURN key.

The method names are misleading.  There are two processes of interest - the shell or other program which Konsole itself started when the session was created (typically bash or some other shell) and the process which currently has control of the terminal.  UNIX documentation usually refers to this as the program group leader.  In Konsole we refer to this as he foreground process - this may be the shell itself.  Additionally, it is not necessary to have both isSubProcessActive() and subProcessPID() since subProcessID() returns -1 if there is no foreground process - which is something that can happen only when the terminal has just started or after it has just ended since after that, the foreground process is either the shell or some other program.

Instead I suggest having just two methods:

terminalProcessId() - Returns the PID of the terminal process which was started by the Konsole part (typically this program will be a shell which the user can enter commands into)
foregroundProcessId() - Returns the PID of the process which is currently controlling the terminal.  This may be the same as terminalProcessId().  Returns -1 if there is no foreground process.
