INSERT/UPDATE against CSV table created by MySQL earlier than 5.1.23
with NULL-able column results in server crash in debug builds.

Starting with 5.1.23 CSV doesn't permit creation of NULL-able columns,
but it is still possible to get such table from older MySQL versions.

Fixed by removing excessive DBUG_ASSERT().

The initialization to zero via LINT_INIT made mysql.test fail.
print_warnings() was suppressed where it should not.

Fixed initialization so that it fakes warnings.

Re-enabled test case after fix

The test case fails on "vanilla" and "no_innodb" builds.
These builds do not include InnoDB.
The test case requires InnoDB.

Added requirement for InnoDB into the test case, so that
it does not start on those builds.

Compiler warned about possible use of uninitialized variable
'warnings' in com_go().

Added LINT_INIT for 'warnings'.

Problem: INTERVAL function implementation doesn't handle NULL range values.

Fix: skip NULL ranges looking for a proper one.

            corrupts a MERGE table

Post-pushbuild fix. The merge test failed on Windows.
The MoveFile() function returned the error code
ERROR_ACCESS_DENIED.

The fix is to use a different name for the file to be
deleted. This is the same trick as we use for the error
code ERROR_ALREADY_EXISTS.

Added ERROR_ACCESS_DENIED to the list of error codes that
require to change the name of the file to be deleted.
