Fix manpage still documenting the old behaviour of building in all jails in -j isn't specified
poudriere.conf: Make it more clear that POUDRIERE_DATA defaults from BASEFS
leftovers: Properly show @dirrm for non-special directories

Reported/Submitted by:	bapt
testport: Add interactive test modes -i and -I

The -I flag may later conflict with the non-ZFS goal as it depends on the startup
automatically rolling back to the @clean snapshot to undo anything the user
has done in the jail.
It's 2013 now, use proper Dd.
lefotvers: Now that @dirrm is showing, properly trim it out when checking for known directories to ignore
bulk: Add debug msg (-vv) to list what missing dependency is causing a package to be rebuilt
leftovers: Also show @dirrm for directories not in PREFIX, ie /var/qmail
Stop populating localbase with mtree it will be done anyway by install-mtree target.

While here include a direct call to install-mtree so the the @preinst snapshot is created after the the mtree is extracted
New options TMPFS_LOCALBASE which allow the localbase to be mounted in tmpfs.
Now use mtree in case of TMPFS_LOCALBASE to discover the leftovers because zfs diff will not see the one in the tmpfs
Improve output of leftovers when found with mtree
Output the plist things in the right order
Add a mechanism able to handle everything in PLIST_SUB, just blacklist PERL_*
specify NO_RESTRICTED from the command line
Unify leftover checking using mtree, no need anymore to check for ZVERSION
Add the blacklist files/directories in the mtree exclude files instead of post processing them
Remove useless type checking
Rename porttree_create_zfs to porttree_create_fs to match that it is now able to work without zfs
Allow to create jails not on zfs
what ever the jails are on: zfs or anything else, metadata are now stored in etc/poudriere.d/jails/<jailname>
what ever the ports are on: zfs or anything else, metadata are now stored in etc/poudriere.d/ports/<portsname>
Add a converter that automatically convert the old metadata to new ones
/!\ Beware if testing that branch! The old metadata are nuked!!!! /!\
