The fix is to rebuild a table if ROW_FORMAT is specified.

to get rid of a name clash among *deleted* files on case-insignificant file systems.

The root cause of this defect is that a call to my_error() is using a
'LEX_STRING' parameter instead of a 'char*'

This patch fixes the failing calls to my_error(), as well as similar calls
found during investigation.

This is a compiling bug (see the instrumentation in the bug report), no test cases provided.

Inserting Data.

The problem was that under some circumstances Field class was not
properly initialized before calling create_length_to_internal_length()
function, which led to assert failure.

The fix is to do the proper initialization.

The user-visible problem was that under some circumstances
CREATE TABLE ... SELECT statement crashed the server or led
to wrong error message (wrong results).
