MCOL-686 Fix BETWEEN performance
...
BETWEEN was executing as a function on each row which meant that extent
elimination couldn't happen. We now execute as a predicate function
instead.

MCOL-697 Limit the return length for LONGBLOB
...
For LONGBLOB the string return length was 4GB for functions which got
converted to -1 and then to 20. This patch sets it to just under 2GB
which we use for LONGBLOB everywhere else.

MCOL-697 Remove 64KB VARCHAR response limit
...
This was a hard coded limit due to StringStore not being able to handle
more than this. It restricts hex() unnecessarily and is now redundant.

MCOL-267 Add basic engine support
...
This patch adds enough support so that cross engines joins with blob
columns in the foreign engines will work. The modifications are as
follows:
* Add CrossEngine support for non-NULL-terminated (binary) data
* Add row data support for blobs (similar to varbinary)
* Add engine support for writing out blob data correctly to the storage
engine API
* Re-enable blob support in the engine plugin
