FreeNAS Code

Make the new tracebacks be on by default

Requested-by: gcooper

Allow Tunables/Sysctls to be enabled/disabled

Rename "loaders" to "tunables"

Push some other iX repo changes out into FreeNAS.

functions.sh:

Some versions of grep had an issue where the "iscompressed" function would fail to discern whether or not a file was compressed based on the file extension. Convert to a case statement instead of using egrep.

notifier.py:

Fix a typo and add an XXX comment in the notifier.sysctl method.

rc.conf.local:

A mostly style change to use $() instead of ``

settings.py:

Update copyright.

create_random_directory_tree.py:

Test tool that helped me reproduce the '/var too small' issue with samba in SF @ r9244.

Other files:

Move hardcoded strings outside in anticipation of pending avatar.conf
infrastructure work where they will no longer be needed.

Do-Not-Merge:

remote syslog server can be a hostname

get rid of ntp fields in Settings and change ix-ntp accordingly

migrate system ntp entries to NTPServer

regenerate ntpserver migration while it is still in time

ntp: split server and options into several fields
(hide it for now)
