The default value is "log" which results in the same /var/log to be
a link pointing to /var/volatile/log.
The user could override this value to "" which causes /var/log to be
a directory on persistent storage.

Respect VOLATILE_LOG_DIR variable. In this way, if the user overrides
this variable to be "", /var/log on the final image would reside on
persistent storage.

Add a new file, fs-perms-persistent-log.txt, which treats /var/log
as a directory instead of a link.
Modify package.bbclass to use this file if VOLATILE_LOG_DIR is set to "".

Randy, Khem, Otavio - this area was the subject of a discussion involving you
around the 1.8 release, if you could review this set and comment that would be
great.

read-only rootfs and persistent /var/log are all custom configurations.
If a user wants a read-only rootfs but a persistent /var/log, he'll need
to do more custom configurations like putting /var/ on a seperate
partition or something else.
The purpose of this patch is to provide an easy way to user to keep
their logs between reboots.
