Bug 1343389

Also happens for yum-utils-1.1.30-37.el6.noarch

+++ This bug was initially created as a clone of Bug #1192946 +++

Description of problem:
needs-restarting returns a list of PID's that have updated/deleted files open due to an previous package upgrade.

https://access.redhat.com/solutions/27943 gives recommendations when in such cases a reboot is mandatory.

needs-restarting should display information in such a way that enables users to decide upon this recommendation and even better give a hint if reboot is required.

Version-Release number of selected component (if applicable):
yum-utils-1.1.30-30.el6.noarch
yum-utils-1.1.31-25.el7_0.noarch

How reproducible:
call needs-restarting on a system with recently upgraded glibc, kernel, hald,...

Actual results:

  Caution!
  Kernel or core library packages have been updated!
  Reboot required!
  See https://access.redhat.com/solutions/27943 for details.


Additional info:
added a new option -r (--reboothint) to needs-restarting.py that adds the desired output.
Patches for RHEL6 and RHEL7 are attached.
