[PATCH 0/7] MR2528: taskkill: Support terminating child processes.

[Paul Gofman (＠gofman)]

Needed for Epic Online Services updater which invokes taskkill with /T flag and fails to replace a file if that didn't actually killed the processes.

There is apparently a bit of refactoring on the way, with most notably using toolhelp snapshot instead of EnumProcesses(). That is more convenient for finding child processes (instead of performing a separate query for parent pid), but I also think that is more consistent in general and gets rid of existing separate query for process name.
