The row is located in the row buffer, pointed by @c m_curr_row member.
Number of columns of the row is stored in @c m_width member (it can be
different from the number of columns in the table to which we insert).
Bitmap @c m_cols indicates which columns are present in the row. It is assumed
that event's table is already open and pointed by @c m_table.
If the same record already exists in the table it can be either overwritten
or an error is reported depending on the value of @c overwrite flag
(error reporting not yet implemented). Note that the matching record can be
different from the row we insert if we use primary keys to identify records in
the table.
The row to be inserted can contain values only for selected columns. The
missing columns are filled with default values using @c prepare_record()
function. If a matching record is found in the table and @c overwritte is
true, the missing columns are taken from it.
@param rli Relay log info (needed for row unpacking).
@param overwrite
Shall we overwrite if the row already exists or signal
error (currently ignored).
@returns Error code on failure, 0 on success.

/*
Around 2007-10-31, I made these classes completely separated from
the new classes (before, there was a complex class hierarchy
involving multiple inheritance; see BUG#31581), by simply copying
and pasting the entire contents of Rows_log_event into
Old_rows_log_event and the entire contents of
{Write|Update|Delete}_rows_log_event into
{Write|Update|Delete}_rows_log_event_old. For clarity, I will keep
the comments marking which code was cut-and-pasted for some time.
With the classes collapsed into one, there is probably some
redundancy (maybe some methods can be simplified and/or removed),
but we keep them this way for now. /Sven
