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

MCOL-494 Don't try to process BLOB/TEXT
...
It is possible for a BLOB/TEXT column to appear in a cross engine join.
This causes an ExeMgr crash later during execution. For now this patch
disable BLOB/TEXT support.
