When copying a page from a backing object into the shadow, all mappings of the source page must therefore be removed. Otherwise, future operations on the object tree may detect that the source page is fully shadowed and thus can be freed.

Consequently, a reservation could be broken mistakenly when it was unable to provide a satisfactory set of pages. Rename the function, correct the errors, and add assertions to detect the error in case it appears again.

To get there, I have created zfs_nextboot() implementation based on two sources, our current simple textual string based approach with added structured boot label PAD structure from OpenZFS. Secondly, all nvlist details are moved to separate source file and restructured a bit. This is done to provide base support to add nvlist add/update feature in followup updates. And finally, the zfsboot/gptzfsboot disk access functions are swapped to use libi386 and libsa.
