Review request for Konsole.


Changes

recreate against master


Summary
-------

Currently, konsole kills the terminal process by sending SIGHUP and optionllay close the pty device. It is quite generic and works well with most terminal process. But it fails with some special programs.

The common root cause  of those 3 bugs is: autossh, irssi and su won't die after receiving SIGHUP. The action of closing pty device does not make them die, either(which really confuses me a bit). 

This patch will adds a last resort: sends SIGKILL to the terminal process, if existing way has failed. 

I feel a bit worried about some implementation details in this patch: annotations, namings, public or private, timeout length, etc. So plese take it as a starting point, if the idea is OK.


This addresses bugs 241709, 251566 and 254600.

Testing
-------

I have tested this patch with 3 profiles contains 'autossh -M 0:7 user at host', 'irssi' and 'su -l' as commnd, and konsole can close session created from those profiles as expected. No regression observed so far.


Thanks,

Jekyll
