Subject: Make Mnesia DCD dump behaviour available via configuration

Setting the new Mnesia parameter 'dump_disc_copies_at_startup' to
'false' will completely disable the DCD dumping while tables are being
loaded. If it is set to 'true' (the default), the same test will now
be performed as for normal dumps, i.e., using the 'dc_dump_limit'
parameter. Previously, the test performed at load time was different
from the one used at runtime, and caused a lot of unnecessary dumping
which slowed down the startup.
