WL#3228 (NDB) : RBR using different table defs on slave/master

Browse source 
This patch adds the ability to store extra field metadata in the table
map event. This data can include pack_length() or field_lenght() for
fields such as CHAR or VARCHAR enabling developers to add code that
can check for compatibilty between master and slave columns. More 
importantly, the extra field metadata can be used to store data from the
master correctly should a VARCHAR field on the master be <= 255 bytes 
while the same field on the slave is > 255 bytes. '

The patch also includes the needed changes to unpack to ensure that data
which is smaller on the master can be unpacked correctly on the slave.

@page How replication of field metadata works.
When a table map is created, the master first calls
Table_map_log_event::get_field_metadata_size() which calculates how many
values will be in the field metadata. Only those fields that require the
extra data are added (see table above). The master then loops through all
of the fields in the table calling the method
Table_map_log_event::get_field_metadata() which returns the values for the
field that will be saved in the metadata and replicated to the slave. Once
all fields have been processed, the table map is written to the binlog
adding the size of the field metadata and the field metadata to the end of
the body of the table map.
When a table map is read on the slave, the field metadata is read from the
table map and passed to the table_def class constructor which saves the
field metadata from the table map into an array based on the type of the
field. Field metadata values not present (those fields that do not use extra
data) in the table map are initialized as zero (0). The array size is the
same as the columns for the table on the slave.
*/
/**
Save the field metadata based on the real_type of the field.
The metadata saved depends on the type of the field. Some fields
store a single byte for pack_length() while others store two bytes
for field_length (max length).
@retval 0 Ok.
TODO: We may want to consider changing the encoding of the information.
Currently, the code attempts to minimize the number of bytes written to
the tablemap. There are at least two other alternatives; 1) using
net_store_length() to store the data allowing it to choose the number of
bytes that are appropriate thereby making the code much easier to
maintain (only 1 place to change the encoding), or 2) use a fixed number
of bytes for each field. The problem with option 1 is that net_store_length()
will use one byte if the value < 251, but 3 bytes if it is > 250. Thus,
for fields like CHAR which can be no larger than 255 characters, the method
will use 3 bytes when the value is > 250. Further, every value that is
encoded using 2 parts (e.g., pack_length, field_length) will be numerically
> 250 therefore will use 3 bytes for eah value. The problem with option 2
is less wasteful for space but does waste 1 byte for every field that does
not encode 2 parts.
