Init script fixes
* Fix regression - "OVERLAY_MOUNTS" should have been "DO_OVERLAY_MOUNTS".
* Fix update-rc.d commands in postinst. Thanx to subzero79@GitHub.
* Fix make sure a filesystem exists before trying to mount in mount_fs()
* Fix local variable usage.
* Fix to read_mtab():
* Strip control characters (space - \040) from /proc/mounts GLOBALY,
not just first occurrence.
* Don't replace unprintable characters ([/-. ]) for use in the variable
name with underscore. No need, just remove them all together.
* Add check_boolean() to check if a user configure option is
set ('yes', 'Yes', 'YES' or any combination there of) OR '1'.
Anything else is considered 'unset'.
* Add a ZFS_POOL_IMPORT to the default config.
* This is a semi colon separated list of pools to import ONLY.
* This is intended for systems which have _a lot_ of pools (from
a SAN for example) and it would be to many to put in the
ZFS_POOL_EXCEPTIONS variable..
* Add a config option "ZPOOL_IMPORT_OPTS" for adding additional options
to "zpool import".
* Add documentation and the chance of overriding the ZPOOL_CACHE
variable in the config file.
* Remove "sort" from find_pools() and setup_snapshot_booting().
Sometimes not available, and not really necessary.
