Use _unref instead of _free _destroy when possible.

Replace g_(ptr_)array_free (foo, TRUE) and g_hash_table_destroy
with respectively g_(ptr_)array_unref (foo) and g_hash_table_unref.

I used this command to generate this patch:
for f in `find -name "*.c"`; do sed -i $f -re 's/g_ptr_array_free \(([^ ,]+), TRUE\)/g_ptr_array_unref \(\1\)/'; done

See Danielle's blog for explanation of possible bug _free can do:
