format: add support for dev_fill() and extra dev_*() debugging.

Support an fs_io dev_fill().
This helps with devices that actually already return 0 on uninitialized
data. It also helps with in memory devices using sparse libs: don't
allocate a block of 0s.

License tweak: LGPL v2.1 vs LGPL v2

The important part is

    b) Use a suitable shared library mechanism for linking with the
    Library.  A suitable mechanism is one that (1) uses at run time a
    copy of the library already present on the user's computer system,
    rather than copying library functions into the executable, and (2)
    will operate properly with a modified version of the library, if
    the user installs one, as long as the modified version is
    interface-compatible with the version that the work was made with.

libf2fs: move the finalize_device() into the io lib.

This is required so that libf2fs.c can be used against any kind
of device (E.g. an in-memory sparse file) just by linking against
something that provides the libf2fs_io.c functions.

libf2fs is currently libf2fs.c + libf2fs_io.c
