  file vi a fd i/o operation. 
  Force explicit invalidation and not rely on implicit invalidation.

Fixed a possible problem with reading of dynamic records
when a write cache is active. The cache must be flushed
whenever a part of the file in the write cache is to be 
read.

Added a read optimization to _mi_read_dynamic_record().

No test case. This was a hypothetical but existing problem.

Post merge changes.

Removed logic in ha_federated::write_row, which checks field query ids in the
loop which builds the query to run on the remote server.

  The Federated storage engine used Field methods that had arbitrary limits on
  the amount of data they could process, which caused problems with data
  over that limit (4K). By removing those Field methods and just using
  features of the String class, we can avoid this problem.

 Changed the error reporting (and a crash) when inserting data into a
 MERGE table that has no underlying tables or no INSERT_METHOD specified
 by reporting that it is read-only.
