This patch introduces a new "rescue=" mount option group for all mount
options for data recovery.
Different rescue sub options are seperated by ':'. E.g
"ro,rescue=nologreplay:usebackuproot".
The original plan was to use ';', but ';' needs to be escaped/quoted,
or it will be interpreted by bash, similar to '|'.
And obviously, user can specify rescue options one by one like:
"ro,rescue=nologreplay,rescue=usebackuproot".
The following mount options are converted to "rescue=", old mount
options are deprecated but still available for compatibility purpose:
- usebackuproot
Now it's "rescue=usebackuproot"
- nologreplay
Now it's "rescue=nologreplay"
