Do not print a warning message when the server's character set is

not found by the client.  This is especially important for PHP, which
only includes the latin1 character set in the bundled libmysql.


libmysql/libmysql.c:
  Do not print a warning message when the server's character set is
  not found by the client.  (In this case, the client has always fallen
  back on the default character set - this change just turns off the
  warning.)
mysys/charset.c:
  Pass flags in from the outside, instead of hard coding MY_WME, in
  add_charset().
