On modern linux distributions (Ubuntu >= 10.10, Debian >= Wheezy),
trying to debug a terminal application fails, with
"ptrace: Operation not permitted".
In order to allow the debugger to attach to the created process, the
process itself needs to inform the kernel of the debugging process.

* If Creator is not executed from terminal, this value is missing.
* If it is executed from a terminal of another type than the stub
it might be wrong.

The stub incorrectly send its pid before reading the environment file,
and qtcreator does interpret that as sign that it can delete the
environment file.

Distinguishes the process that starts the terminal from the stub
process, as on mac to support Terminal.app they are different.
Handle the stub not through the process that starts the terminal,
but through the local socket (on *nix).
Replace the blocking wait(...) in the main thread, with a nonblocking
wait in the signal handler when receiving a SIGCHLD, to leave the
main thread able to handle communication with creator.
This change allows the use of terminal emulator commands
that share a single instance or that fork.
So this is also the real fix for QTCREATORBUG-1633 on linux.
If creator crashes the stub and the debugged program live on.
This was done on purpose, it could be changed if considered better.

Setting Tools/Options/Environment/General/Terminal to one of the
following works now as expected.
1. xterm -e
2. aterm -e
3. rxvt -e
4. urxvt -e
5. xfce4-terminal -x
6. konsole --nofork -e
7. gnome-terminal -x
Without the '--nofork' option for konsole, from creator's pov, the
terminal emulator will finish immediately and therefore creator closes
the local socket. As a result of this, the user is presented with sth.
like this (from the stub):
Cannot connect creator comm socket /tmp/qt_temp.A13523/stub-socket:
No such file or directory.
