Problem: when embedding a character string with introducer with charset X
into a SQL query which is generally in character set Y, the string constants
were escaped according to their own character set (i.e.X), then after reading
such a "mixed" query from binlog, the string constants were unescaped
using character set of the query (i.e. Y), instead of X, which gave wrong
results or even syntax errors with tricky charsets (e.g. sjis)
Fix: when embedding a string constant of charset X into a query of charset Y,
the string constant is now escaped according to character Y, instead of
its own character set X.

  Problem: GROUP_CONCAT on a multi-byte column can truncate
  in the middle of a multibyte character when applying
  group_concat_max_len limit. It produces an invalid
  multi-byte character in the result string.
  
The second, easier version - reusing old "warning_for_row" flag,
instead of introducing of "result_is_full" - which was
added in the previous commit.
