In CSV import, instead of SCWARN_IMPORT_RANGE_OVERFLOW use
SCWARN_IMPORT_ROW_OVERFLOW and SCWARN_IMPORT_COLUMN_OVERFLOW that already
existed, additionally introduced SCWARN_IMPORT_CELL_OVERFLOW if single field
data exceeds STRING_MAXLEN.

Row overflow takes precedence over column overflow that takes precedence over
cell overflow.

Without this, calculation upon import may incorrectly show #VALUE!
in some cells when the iterative calculation option is turned on.

This is on par with what we do during the ods document import.

Taking a reference to double makes no sense here.  Plus the bool.

CSV and other text formats may come with line sizes >64k that so far were
truncated due to limitations in ByteString/UniString/String, even if one line
consists of several fields that each are <64k.

Introduced additional SvStream methods that read into rtl::OString and
rtl::OUString and let SvStream::ReadUniOrByteStringLine() fill solely an
rtl::OUString.

Made Calc CSV import use those.
