[gnome-db] Memory leaks

[Phil Longstaff <plongstaff rogers com>]

I am seeing some memory leaks using libgda 3.0:

==26959== 20 bytes in 4 blocks are definitely lost in loss record 52 of 270
==26959==    at 0x40233F0: malloc (in 
/usr/lib/valgrind/x86-linux/vgpreload_memcheck.so)

==26959==    by 0x7730848: gda_init (gda-init.c:99)
- gda_dict_dtd is never freed

==26959==    by 0x76ECC94: gda_client_open_connection_from_string 
(gda-client.c:553)
- filename is never freed (though it is passed to g_strdup()).  There 
are possibly other instances of this one.

- The lexer uses g_strdup() but the strings may not be released.
