Fix for bugs #68114 (Build fails on OS X due to undefined symbols)
and #68657 (Reading 4 byte floats with Mysqli and libmysqlclient
has rounding errors).
The patch removes support for Decimal floating point numbers and
now defaults to using similar logic as what libmysqlclient does:
convert a 4 byte floating point number into a string, and then the
string into a double. The quirks of MySQL are maintained as seen in
Field_Float::val_str()
