Fix for bug #21205: Different number of digits for float/double/real in --ps-protocol
Various parts of code used different 'precision' arguments for sprintf("%g") when converting
floating point numbers to a string. This led to differences in results in some cases
depending on whether the text-based or prepared statements protocol is used for a query.
Fixed by changing arguments to sprintf("%g") to always be 15 (DBL_DIG) so that results are
consistent regardless of the protocol.
This patch will be null-merged to 6.0 as the problem does not exists there (fixed by the
patch for WL#2934).
client/sql_string.cc:
Use 15 (DBL_DIG) as a precision argument for sprintf(), as Field_double::val_str() does.
libmysql/libmysql.c:
Use 15 (DBL_DIG) as a precision argument for sprintf(), as Field_double::val_str() does.

Fixed test results to take additional precision into account.
