Today the node data is copied in db_fetch() on each data base read in

read_node() is the only caller of db_fetch() which isn't freeing the
returned data area immediately after using it. The other callers don't
modify the returned data, so they don't need the data to be copied.
Move copying of the data into read_node(), resulting in a speedup of
the other callers due to no memory allocation and no copying being
needed anymore.
This allows to let db_fetch() return a pointer to const data.
As db_fetch() can't return any error other than ENOENT now, error
handling for the callers can be simplified.
