This patch adds supporting dump_file, which can extract a file from image.
You can simply select [yes|no] when doing dump.f2fs -i [inode number] [img].

The compile time option BLKDISCARD conflicts with ioctl code
for discard. This causes discard to fail with "Info: This
device doesn't support TRIM". Rename compile time option
to WITH_BLKDISCARD.

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

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.

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.

Currently mkfs followed by fsck will fail with
[f2fs_crc_valid: 351] CRC validation failed: cal_crc = 4076150800 blk_crc = 0 buff_size = 0x0
This is because the validatie_checkpoint() tries to read and checksum the
cp page 2, and it is invoked on both cp packs.
But format only writes the page 1 of the 2nd checkpoint pack.

This change allows for f2fs_format to work on a non-standard device (e.g.
sparse-memory backed file).
Removes direct access to config.fd from within f2fs_format.c.
Now, f2fs_format_device() can be made to work against any device by
providing
f2fs_finalize_device()
f2fs_trim_device()
and the lib2fs.c functions
ASCIIToUNICODE
dev_write
f2fs_cal_crc32
f2fs_set_bit
log_base_2
This will allow Android's fastboot to use f2fs against a libsparse.
