When we're dumping a fast symlink inode, we print some odd things to
stdout. To clean this up, first don't print inline data EA, since the
inode dump doesn't display file and directory contents. Then, teach
the inode dump function how to print out either an inline data fast
symlink or a non-inline data fast symlink.
(This is a follow-up to the earlier patch "debugfs: Only print the
first 60 bytes from i_block on a fast symlink")

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().

Currently ext2fs_file_read/write are used to copy data from/to a file.
But they manipulate data by blocksize. For supporting inline data, we
handle it in two new fucntions called ext2fs_file_read/write_inline_data.
In read path the implementation is straightforward. But in write path
things get more complicated because if the size of data is greater than
the maximum size of inline data we will expand this file. So now we
will check this in ext2fs_inline_data_set. If this inode doesn't have
enough space, it will return EXT2_ET_INLINE_DATA_NO_SPACE error. Then
the caller will check this error and tries to expand the file.
The following commands in debugfs can handle inline_data feature after
applying this patch:

- rdump

In practice, it is **extremely** rare for users to try to use more
than the first backup superblock located at the beginning of block
group #1. (i.e., at block number 32768 for file systems with a 4k
block size). This new compat feature restricts the backup superblock
to block group #1 and the last block group in the file system.
Aside from reducing the overhead of the file system by a small number
of blocks, by eliminating the rest of the backup superblocks, it
allows us to have a much more flexible metadata layout. For example,
we can force all of the allocation bitmaps and inode table blocks to
the beginning of the disk, which allows most of the disk to be
exclusively used for contiguous data blocks.
This simplifies taking advantage of certain HDD specific features,
such as Shingled Magnetic Recording (aka Shingled Drives), and the
TCG's OPAL Storage Specification where having a simple mapping between
LBA block ranges and the data blocks used by the file system can make
life much simpler.

In response to reviewer comments, commit fe56188b07 included changes

supplies in lieu of a default to parse_ulonglong(). Also, revert to
the more descriptive original error messages with mods per reviewer

The s_desc_size in the superblock specifies the group descriptor
size in bytes, but in various places the EXT4_FEATURE_INCOMPAT_64BIT
flag implies that the descriptor size is EXT2_MIN_DESC_SIZE_64BIT
(64 bytes) instead of checking the actual size. In other places,
the s_desc_size field is used without checking for INCOMPAT_64BIT.
In the case of ext2fs_group_desc() the s_desc_size was being ignored,
and assumed to be sizeof(struct ext4_group_desc), which would result
in garbage for any but the first group descriptor. Similarly, in
ext2fs_group_desc_csum() and print_csum() they assumed that the
maximum group descriptor size was sizeof(struct ext4_group_desc).
Fix these functions to use the actual superblock s_desc_size if
INCOMPAT_64BIT.
Conversely, in ext2fs_swap_group_desc2() s_desc_size was used
without checking for INCOMPAT_64BIT being set.
The e2fsprogs behaviour is different than that of the kernel,
which always checks INCOMPAT_64BIT, and only uses s_desc_size to
determine the offset of group descriptors and what range of bytes
to checksum.
Allow specifying the s_desc_size field at mke2fs time with the
"-E desc_size=NNN" option. Allow a power-of-two s_desc_size
value up to s_blocksize if INCOMPAT_64BIT is specified. This
is not expected to be used by regular users at this time, so it
is not currently documented in the mke2fs usage or man page.
Add m_desc_size_128, f_desc_size_128, and f_desc_bad test cases to
verify mke2fs and e2fsck handling of larger group descriptor sizes.

Accessing name_len (and file_type) in ext4_dir_entry structure is
somewhat problematic because on big endian architecture we need to now
whether we are really dealing with ext4_dir_entry (which has u16
name_len which needs byte swapping) or ext4_dir_entry_2 (which has u8
name_len which must not be byte swapped).
Currently the code is somewhat surprising and name_len is always
treated as u16 and byte swapped (flag EXT2_DIRBLOCK_V2_STRUCT isn't
ever used) and then masking of name_len is used to access real
name_len or file_type. Doing things this way in applications using
libext2fs is unexpected to say the least (more natural is to type
struct ext4_dir_entry * to struct ext4_dir_entry_2 * but that gives
