Fix potential 2**32-1 overflow by using e2p_percent()
Add a new functiom, e2p_percent(), which correct calculates the percentage
of a number based on a given percentage, without worrying about overflow
issues. This is used where we calculate the number of reserved blocks using
a percentage of the total number of blocks in a filesystem.
Based on patches from Eric Sandeen, but generalized to use this new function.

hello,
e2p_percent() doesn't work for zero percent (``mke2fs -m0'' gets killed with
SIGFPE).
is there a reason for not simply using 64 bit arithmetic? perhaps to avoid
overflows for 7e+9TB file-systems :-), or just for correctness...
So, here is the patch that fixes this. In order to avoid integer overflows,
we pick 16 more bits to store ``base'' and do the exact division on 48 bits.
Since ``100 * base'' always fits in 48 bits, there's never overflow. This
still work if we remplace 'unsigned int' by 'unsigned long long'.
cheers,
-- Alexandre

Fix potential 2**32-1 overflow problems by ext2fs_div_ceil()
Add a new function, ext2fs_div_ceil(), which correctly calculates a division
of two unsigned integer where the result is always rounded up the next
largest integer. This is used everywhere where we might have
previously caused an overflow when the number of blocks
or inodes is too close to 2**32-1.
Based on patches from Eric Sandeen, but generalized to use this new function

Detect overflows in loop counters
For loops such as:
for (i=1; i <= fs->super->s_blocks_count; i++) {
<do_stuff>
}
if i is an int and s_blocks_count is (2^32-1), the condition is never false.
Change these loops to:
for (i=1; i <= fs->super->s_blocks_count && i > 0; i++) {
<do_stuff>
}
to stop the loop when we overflow i

Fix signed vs unsigned printf format strings for block and inode numbers
There were still some %d's lurking when we print blocks & inodes; also
many of the counters in the e2fsck_struct were signed, and probably
need to be unsigned to avoid overflows.

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.

The e2fsprogs package contains a number of utilities for creating,

repair filesystem inconsistencies after an unclean shutdown), mke2fs
(used to initialize a partition to contain an empty ext2 filesystem),
debugfs (used to examine the internal structure of a filesystem, to
manually repair a corrupted filesystem, or to create test cases for
e2fsck), tune2fs (used to modify filesystem parameters), and most of
the other core ext2fs filesystem utilities.
