When do_freefrag() is called from debugfs, the value of optind is
not reset. Rectify that by calling reset_getopt().

Currently there are many uses of ext2fs_close() which might be wrong.
First of all ext2fs_close() does not set the ext2_filsys pointer to NULL
so the caller is responsible for clearing it, however there are some
cases there we do not do it.
Second of all very small number of users of ext2fs_close() actually
check the return value. If there is a problem in ext2fs_close() it will
not even free the ext2_filsys structure, but majority of users expect it
to do so.
To fix both problems this commit introduces a new helper
ext2fs_close_free() which will not only check for the return value and
free the ext2_filsys structure if the call to ext2fs_close2() failed,
but it will also set the ext2_filsys pointer to NULL.
Replace every use of ext2fs_close() in e2fsprogs tools with
ext2fs_close_free() - there is no real reason to keep using
ext2fs_close().

An integer overflow could happen if the file system is large and has
very large contiguous chunks of free space.

Enable the use of 64-bit bitmaps, so e2freefrag will work on file
systems with the 64-bit feature enabled. In addition, enable the
rbtree-based bitmaps, which significantly saves the amount of memory
required (from 97 megs to 1.7 megs for an empty 3T file system) at the
cost of additional CPU overhead (but we will claw back some of the
additional CPU overhead in the next commit).

The freefrag command provides the functionality of e2freefrag on the
currently open file system in debugfs.

After:
# mke2fs -O ^has_journal,^resize_inode,^uninit_bg,extent,meta_bg,flex_bg,bigalloc /dev/sda
# e2freefrag /dev/sda
It will report error message like:
Illegal block number passed to ext2fs_test_block_bitmap #1732133 for block bitmap for /dev/sda
Illegal block number passed to ext2fs_test_block_bitmap #1732134 for block bitmap for /dev/sda
Illegal block number passed to ext2fs_test_block_bitmap #1732135 for block bitmap for /dev/sda
One bit in bitmap of bigalloc-ext4 means a cluster not a block,
therefore ext2fs_fast_test_block_bitmap2 should check cluster.

The DEFS line in MCONFIG had gotten so long that it exceeded 4k, and
this was starting to cause some tools heartburn. It also made "make
V=1" almost useless, since trying to following the individual commands
run by make was lost in the noise of all of the defines.
So fix this by putting the configure-generated defines in lib/config.h
and the directory pathnames to lib/dirpaths.h.
In addition, clean up some vestigal defines in configure.in and in the
Makefiles to further shorten the cc command lines.

There is no need to print out a "bad option" message; getopt
does that for us, and in fact will change "c" to "?" so
it's not even useful.

The getopt() function returns an int, not a char. On systems where the
default char is unsigned (like ppc), we get weird behavior where -1 is
truncated to 0xff but compared to (int)-1.
Also fix this same bug for two test programs, test_rel and iscan,
which aren't currently used at the moment.

If the file system has a non-zero s_first_data_block, as is the case
when the block size is 1kb, e2freefrag would incorrectly try to
reference invalid data blocks in the block allocation bitmap.

"Free chunks" is confusing since it has nothing to do with the
chunksize; use "free extents" instead.
Also add a missing newline in an error message.
