1) Support of partitioning by connect. A table can be partitioned
by files, this is an enhanced MULTIPLE table. It can be also
partitioned by sub-tables like TBL and this enables table sharding.
2) Handling a CONNECT bug that causes in some cases extraneous rows
to remain in the table after an UPDATE or DELETE when the command
uses indexing (for not fixed file tables). Until a real fix is
done, CONNECT tries to ignore indexing and if it cannot do it
abort the command with an error message.

in this version. Sure enough, it never caused any improvement in
the execution speed and rather caused a small increase of execution
time. This is probably because values are sorted by rowid in each
range of CONNECT indexes. This could be reconsidered if a customer
have a need for processing very big files.
- Fix a bug in ha_connect::CheckCond. The negated form of BETWEEN and
IS NULL operators was not recognized.

- Implement a first support of the ALTER TABLE command. This fixes MDEV-5440
but does much more than only that. See the details of how ALTER is supported
in the new documentation and also in MDEV-5440 comment.
This is done principally by implementing for CONNECT the virtual function
check_if_supported_inplace_alter.
