libext2fs: fix memory leak when failing to iterate inline_data directory
The xattr_get method returns to us a pointer to a buffer containing
the EA value. If for some reason we decide to fail out of iterating
the EA part of an inline-data directory, we must free the buffer that

libext2fs: strict inline data overwrite should not return ENOSPC
If we're doing a strict overwrite (same data size) of data in an
inline data file, we should be able to skip the size check. If the
in-core EA representation is fine but the on-disk EA is slightly
corrupt (this happens when fixing minor errors in an inline dir), the
ext2fs_xattr_inode_max_size() call, which reads the disk EA, can lead
us to think that there's no space when in reality there is no issue
with doing a strict overwrite.

libext2fs: repair side effects when iterating dirents in inline dirs
In ext2fs_inline_data_dir_iterate(), we must be very careful to undo
any modifications we make to the dir_context pointer passed in by the
caller, because it's entirely possible that the caller will still want
to do something with the ctx or something inside.
Specifically, ext2fs_dblist_dir_iterate() wants to be able to free
ctx->buf, and it reuses the ctx for multiple dblist entries. That
means that assigning ctx->buf will cause weird crashes at the end of
dir_iterate().
Since we're being careful with ctx, we might as well handle adding the
INLINE_DATA flag to ctx->flags for ext2fs_process_dir_block, since the
dblist caller forgets to unset the flag before reusing the ctx.
This fixes some crashes and valgrind complaints in resize2fs, and is
necessary for the next patch, which fixes resize2fs not to corrupt
inline_data filesystems.

libext2fs: during inlinedata expand, don't corrupt inode
When expanding an inline data inode, it's possible that the reduction
in the size of the EA structures causes the freeing of the EA block,
which changes the inode. If this happens, the local version of the
inode that ext2fs_inline_data_expand was modifying will be out of sync
with what's on the disk. This local copy gets written out to disk
after a block allocation, at which point it's possible that the inode
EA block and logical block zero point to the same physical block,
which is bad news.
Therefore, write the local copy to disk before removing the inline
data EA, and reread it afterwards.

libext2fs: don't fail when doing a strict rewrite of inline data
ext2fs_inline_data_set() tries to ensure that there is sufficient free
space in the inode to store the inline data. Unfortunately, it gets
the check wrong -- ext2fs_xattr_inode_max_size() returns the amount of
unused bytes in the EA area, and _data_set() doesn't factor in the
size of the existing inline data. Therefore, a strict rewrite of an
N-byte inlinedata with another N-byte inlinedata fails.
Fix the code to do the size check correctly.

libext2fs: handle inline data in read/write function
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:
- dump
- cat
- rdump
- write

Inline_data is handled in dir iterator because a lot of commands use
this function to traverse directory entries in debugfs. We need to
handle inline_data individually because inline_data is saved in two
places. One is in i_block, and another is in ibody extended attribute.
After applied this commit, the following commands in debugfs can
support the inline_data feature:
- cd
- chroot
- link*
- ls
- ncheck
- pwd
- unlink
* TODO: Inline_data doesn't expand to ibody extended attribute because
link command doesn't handle DIR_NO_SPACE error until now. But if we
have already expanded inline data to ibody ea area, link command can
occupy this space.
