d07bddc153 Disable KeyboardInterrupt, just exit on SIGINT. 
The KeyboardInterrupt exception doesn't get raised if the script
is stuck in a blocking call, i.e., inside the check_event function.
So pressing CTRL+C has no effect.

This patch disables the exception, reverting to the OS' default
behaviour for the SIGINT signal (i.e., terminate the program).

9393180c0c Better error handling in loader threads. 
The main script currently hangs if any loader fails to connect to
the database. This happens because connection exceptions from
PGLoader._postinit are not handled, and the main script keeps
waiting for "finished" events that never happen.

This patch ensures that exceptions in the loader threads are noted
by the main script, and that an appropriate exit status is returned
to the OS.

Changes in pgloader/pgloader.py:
 - Handle all exceptions in PGLoader.run
 - Add a boolean "success" flag to PGLoader class that determines
   whether any errors occured within that object's main thread
 - Whenever an exception happens within a thread, set the "success"
   flag to false and call "terminate"

Changes in pgloader.py:
 - check "success" flag on all threads after they finish
 - return 0 on success and 1 on any error
 - the script no longer returns the result of "print_summary",
   just 0 or 1.

a062db184d Avoid calling self.fd.tell() when we're reading from stdin. 
That means the options --load-from-stdin and --boundaries are not compatible.
