Block groups documentation has three, first-level section headings.
These headings' text become toctree entries and the first one "Layout"
becomes docs title in the output, which isn't conveying the docs
contents.
Add explicit title heading and demote the rest.

Since the default ext4 group desc size is 64 now (assuming that the
64-bit feature is enbled). And the size mentioned in this doc is 64 too.
Change it to 64.

The conversion tools used during DocBook/LaTeX/html/Markdown->ReST
conversion and some cut-and-pasted text contain some characters that
aren't easily reachable on standard keyboards and/or could cause
troubles when parsed by the documentation build system.
Replace the occurences of the following characters:
- U+2217 ('∗'): ASTERISK OPERATOR
use ASCII asterisk instead of the ASTERISK OPERATOR

This commit aims to fix the following issues in ext4 documentation:
- Flexible block group docs said that the aim was to group block
metadata together instead of block group metadata.
- The documentation consistly uses "location" instead of "block number".
It is easy to confuse location to be an absolute offset on disk. Added
a line to clarify all location values are in terms of block numbers.
- Dirent2 docs said that the rec_len field is shortened instead of the
name_len field.
- Typo in bg_checksum description.
- Inode size is 160 bytes now, and hence i_extra_isize is now 32.
- Cluster size formula was incorrect, it did not include the +10 to
s_log_cluster_size value.
- Typo: there were two s_wtime_hi in the superblock struct.
- Superblock struct was outdated, added the new fields which were part
of s_reserved earlier.
- Multiple mount protection seems to be implemented in fs/ext4/mmp.c.

Move the ext4 data structures book to Documentation/filesystems/ext4/
since the administrative information moved elsewhere.
