WL#4078: Document binary format of binlog entries

Documented some binlog events using doxygen. More will be done later.
Also fixed typos in other comments and added remarks about dubious code.
Only comments are affected, there is no change to the actual code.

We follow this logic:
- when stmt starts, first_successful_insert_id_in_prev_stmt contains the
first insert id successfully inserted by the previous stmt.
- as stmt makes progress, handler::insert_id_for_cur_row changes; every
time get_auto_increment() is called, auto_inc_intervals_for_binlog is
augmented with the reserved interval (if statement-based binlogging).

every time get_auto_increment() is called,
auto_inc_intervals_in_cur_stmt_for_binlog is augmented with the
reserved interval (if statement-based binlogging).
- at first successful insertion of an autogenerated value,
first_successful_insert_id_in_cur_stmt is set to
handler::insert_id_for_cur_row.
- when stmt goes to binlog, auto_inc_intervals_for_binlog is
binlogged if non-empty.

auto_inc_intervals_in_cur_stmt_for_binlog is binlogged if
non-empty.
- when stmt ends, first_successful_insert_id_in_prev_stmt is set to
