Changed another unecessary use of Item_string into LEX_STRING (in sp_pcontext).

As a fix, my_charset_bin is now used in master-slave packets instead
of system_charset_info.

  SET NAMES BINARY now works

  new file

  As far as bk could not apply delta,
  I removed it.  Now I'm adding the
  new version into the tree again.

  Delete: mysql-test/r/ctype_many.result

  I could not commit it, bk told it can't apply binary delta
  for textual file.

No commit message

  Automatic client-server charset recoding has been added

  Bug fix
  0 stayed for length here, now it is charset.

  Copy as is if src or dst are binary

  binary comparing alway must be used, because sort_string() is executed for textual data.
