bugfix: Increase available memory during upgrade/install process It is possible for the system to run out of memory when dealing with large file uploads and installs. As part of the upgrade procedure shutdown services that are not essential for node operations to allow more memory for install to take place. Includes changes to linkled to indicate this new state as it will be shutdown as part of the cleanup process. Memory gain (approximate) dropbear 100kb linkled 200kb logd 200kb odhcp 100kb snmpd 500kb xinetd 100kb Total(approximate): 1200kb (around %4 on 32mb devices) This is somewhat similar to files/usr/local/bin/upgrade_kill_prep except that it kills only a select group of services so that the system can handle the file upload while upgrade_kill_prep does the final system cleanup to run the full upgrade. ref AREDN->ticket:204 Change-Id: Ic6d3aa028725064a97c4723f6d9b36e1e51d87a7
