Eric Sandeen bb1a46a430 Fix loops over group descriptors to prevent 2**32-1 block number overflows
For loops iterating over all group descriptors, consistently define
first_block and last_block in a way that they are inclusive of the
range, and do not overflow.

Previously on the last block group we did a test of <= first +
dec_blocks; this would actually wrap back to 0 for a total block count
of 2^32-1

Also add handling of last block group which may be smaller.

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.

  block.c, bmove.c, dirblock.c, fileio.c: Explicitly cast

Theodore Ts'o 5be8dc2143 Many files:
dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more paranoid
  	about validating the directory counts from the block group
  	information.
  all files: Don't include stdlib.h anymore; include it in ext2_fs.h,
  	since that file requires stdlib.h
ChangeLog, Makefile.in, dirinfo.c:
  dirinfo.c (e2fsck_add_dir_info): Use ext2fs_get_num_dirs instead of
  	e2fsck_get_num_dirs, which has been removed.
  Makefile.in (PROGS): Remove @EXTRA_PROGS@, since we don't want to
  	compile and install flushb.
ChangeLog, configure.in:
  Remove @EXTRA_PROGS@, since we aren't using it in 2fsck/Makefile.in anymore
ChangeLog, Makefile.in:
  Install debugfs in /sbin, instead of /usr/sbin.
libext2fs.texinfo:
  Update version string to be 1.12
Makefile.in:
  Fix bug in find script which made the exclusion list, where a '-' was
  missing from an -name option.
