Slave starts accepting and handling rows of master's tables which have more columns.
The most important part of implementation is how to caclulate the amount of bytes to
skip for unknown by slave column.
To solve that issue this WL adopts results of WL#3228 which introduces an addon to
table_map event that carries the necessary part of information about sizes of data of columns.

WL#3915 master's cols > slave
basic tests checking altering and skipping extra fields by slave.
The fields can be of any possible types.
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.

Reduce case and formalise into something we should be
able to use in mysql-test-run.

Test that we can start a MySQL Server with a default multibyte charset with
NDB running. Test *really* basic functionality too.

Bug was updated on May 30th by Tomas to say that hasn't been seen in PB
since global dict cache rewrite. This test should probably be enabled then.

This is somewhat related to BUG#26675 (ndb_connectstring not reported
in show global variables)

- add odirect option for lcp+backup+redo log to lower CPU/kswapd usage
- writing odirect removes need for kernel write buffers avoiding kswapd to kick in
