UBIFS: introduce more I/O helpers
Introduce the following I/O helper functions: 'ubifs_leb_read()', 'ubifs_leb_write()', 'ubifs_leb_change()', 'ubifs_leb_unmap()', 'ubifs_leb_map()', 'ubifs_is_mapped(). The idea is to wrap all UBI I/O functions in order to encapsulate various assertions and error path handling (error message, stack dump, switching to R/O mode). And there are some other benefits of this which will be used in the following patches. This patch does not switch whole UBIFS to use these functions yet.
