Subject: Tentative implementation of WL#4165 Prepared statements: validation
 WL#4166 Prepared statements: automatic re-prepare Fixes Bug#27430 Crash in
 subquery code when in PS and table DDL changed after PREPARE Bug#27690
 Re-execution of prepared statement after table was replaced with a view
 crashes Bug#27420 A combination of PS and view operations cause error +
 assertion on shutdown

The basic idea of the patch is to keep track of table metadata between
prepared statement prepare and execute. If some table used in the statement
has changed, the prepared statement is re-prepared before execution.

See WL#4165 and WL#4166 contents and comments in the code for details
of the implementation.
