  Make IM ports change with MTR_BUILD_THREAD

Added FIELD_TYPE_BIT to field method 'needs_quotes' to make BIT columns
work.

even when --ledir option is specified. (Bug #13774)

1. Made sure that base64 string is terminated with NUL.
2. Made calculation of needed size for base64 string exact.
Added checks in test for the above two fixes.
