collation

By default constant strings in second parameter of date_time() have case
insensitive collation. Because of this expressions date_format(f,'%m') and 
date_format(f,'%M') wrongly becomes equal, which results in choosing wrong 
column to sort by.

Now if second parameter of date_format() is constant then it's collation is 
changed to case sensitive.

 Modified my_dir(). Now this function skips hidden and system
 files which sometimes are created by Windows.
 NOTE. The fix is similar to the previuos one (05 July 2004)
 except for correct setting of the 'attrib' variable value
 (within the previous fix this variable was left uninitialized
 when my_dir() was called with My_flags & MY_WANT_STAT == 0).

fix for Valgrind errors: query_id needs to be inited early (already fixed in 5.0 by Konstantin) and so does client_capabilities (not fixed in 5.0);
because they are used by net_printf() and push_warning(), which can be called if check_connection() fails.
