to protect applications that attempt to compile
-D_FILE_OFFSET_BITS=64, since this inexplicably changes ino_t(!?). So
we use ext2_ino_t to avoid an unexpected ABI change.

Many files:
inode.c (ext2fs_open_inode_scan): Initialize the group variables
so that we don't need to call get_next_blockgroup() the first
time around. Saves a bit of time, and prevents us from
needing to assign -1 to current_group (which is an unsigned
value).
icount.c (insert_icount_el): Cast the estimated number of inodes
from a float to an ino_t.
alloc.c, alloc_tables.c, badlbocks.c, bb_compat.c, bb_inode.c,
bitmaps.c, bitops.c, block.c, bmap.c, bmove.c, brel_ma.c,

dblist_dir.c, dir_iterate.c, dirblock.c, dupfs.c, expanddir.c,

rw_bitmaps.c, swapfs.c, test_io.c, tst_badblocks.c,
tst_getsize.c, tst_iscan.c, unix_io.c, unlink.c, valid_blk.c,
version.c: If EXT2_FLAT_INCLUDES is defined, then assume all
of the ext2-specific header files are in a flat directory.
block.c, bmove.c, dirblock.c, fileio.c: Explicitly cast
all assignments from void * to be compatible with C++.
closefs.c (ext2fs_flush): Add a call to io_channel_flush() to
make sure the contents of the disk are flushed to disk.
dblist.c (ext2fs_add_dir_block): Change new to be new_entry to
avoid C++ namespace clash.
bitmaps.c (ext2fs_copy_bitmap): Change new to be new_map to
avoid C++ namespace clash.
