Luis Soares 4923b4157c BUG#50018: binlog corruption when table has many columns 
For tables with metadata sizes ranging from 251 to 255 the size
of the event data (m_data_size) was being improperly calculated
in the Table_map_log_event constructor. This was due to the fact
that when writing the Table_map_log_event body (in
Table_map_log_event::write_data_body) a call to net_store_length
is made for packing the m_field_metadata_size. It happens that
net_store_length uses *one* byte for storing
m_field_metadata_size when it is smaller than 251 but *three*
bytes when it exceeds that value. BUG 42749 had already
pinpointed and fix this fact, but the fix was incomplete, as the
calculation in the Table_map_log_event constructor considers 255
instead of 251 as the threshold to increment m_data_size by
three. Thence, the window for having a mismatch between the
number of bytes written and the number of bytes accounted in the
event length (m_data_size) was left open for
m_field_metadata_size values between 251 and 255.

We fix this by changing the condition in the Table_map_log_event
constructor to match the one in the net_store_length, ie,
increment one byte if m_field_metadata_size < 251 and three if it
exceeds this value.

#
# BUG#42749: infinite loop writing to row based binlog - processlist shows
# "freeing items"
#
# BUG#50018: binlog corruption when table has many columns
#
# WHY
# ===
#
# This bug would make table map event to report data_written one
# byte less than what would actually be written in its body. This
# would cause one byte shorter event end_log_pos. The ultimate
# impact was that it would make fixing the position in
# MYSQL_BIN_LOG::write_cache bogus or end up in an infinite loop.
#
# HOW
# ===
#
# Checking that the patch fixes the problem is done as follows:
#
# i) tables with several fields is created (above and below a 251
# metadata size threshold)
# ii) an insert is performed;
# iii) the logs are flushed;
# iv) mysqlbinlog is used to check if it succeeds.
#
# In step iv), before the bug was fixed, the test case would fail
# with mysqlbinlog reporting that it was unable to succeed in
# reading the event.
