[cover] Don't mark stopped node as lost

Nodes that were stopped with cover:stop/1 were marked as lost and
would be reconnected if a nodeup was later received for a node with
the same name. This has been corrected.
[cover] Remove stopped node also from lost_nodes list

A nodes that was stopped with cover:stop/1 while marked as lost would
not be removed from the list of lost nodes. Therefore, if a nodeup was
later received for a node with the same name, it would be
reconnected. This has been corrected.
ssl & orber: Remove ssl:pid/1 (has been pointless since R14)
stdlib: Updated otp_internal to reflect removal of deprecated function

Note the comment in this file incorrectly stated that ssl:pid/1 should be
removed in R17, the intention has always been R16. This function
has never done anything relevant for the new ssl implementation that is
default in R14 and the only available one in R15.
[cover] Fix timing dependent bug in cover_SUITE:reconnect

Adding a timer:sleep between these two lines:

    net_kernel:disconnect(N1),
    [] = cover:which_nodes(),

This is to make sure the disconnect is detected by cover before
checking that the node is gone.
ssl: Make TLS-1.2 default version
erts,hipe: Make hipe compiler ask running emulator about process struct offsets

Changes in "struct process" has made native code more depenedent on if the
executing emulator is smp enabled or not.

This commit will make a default built hipe compiler (without -xcomp)
to ask the running emulator about process struct offsets. This will
make native code work (again) as long as the same emulator is used for
compilation as well as execution of the native code.
[test_server] Stop cover on node after node is terminated

Before terminating slave nodes, test_server calls cover:flush/1 to
fetch data from the node without actually stopping cover on this
node. If cover is not stopped for the node and a new node with the
same name is started, then cover will be started on the new node. To
avoid this test_server now calls cover:stop/1 after the slave node is
terminated.
[common_test] Stop cover on slave node after node is terminated

Before terminating slave nodes, common_test calls cover:flush/1 to
fetch data from the node without actually stopping cover on this
node. If cover is not stopped for the node and a new node with the
same name is started, then cover will be started on the new node. To
avoid this common_test now calls cover:stop/1 after the slave node is
terminated.
[cover] Cleanup by stopping cover between tests

If one test failed, the next would sometimes also fail since cover was
not stopped.
