add /etc/system.d support
100%
Description
This adds support for kernel tunables via /etc/system.d. With this change modules can independently provide kernel customization in a simplified manner. Instead of modifying /etc/system file, each module can add a file in /etc/system.d directory. Thus distribution specific tunables are cleanly delineated from user settings. It also enables distributions to easily deliver tunables via patch if needed.

Testing notes:
From Alexander Eremin:
Tested on OpenIndiana using various settings in /etc/system.d/*, also Nexenta have used this in production for some time.
I've done additional testing setting hires_tick to 1 and 0 in various combinations within /etc/system and /etc/system.d/test and found that /etc/system wins as expected. Also confirmed that changes to /etc/system.d/test provoke boot archive updates on reboot.
Testing using boot -a and choosing /dev/null for the system file properly ignores anything set in a fragment file as expected.
