fix srp_anon ciphers suites requiring certificates to work.

This problem was not caught by the test suites since all PSK and SRP
suites where always tested with certificates. Split those tests into
test with and without certificates.
Use a set to store ref registers in beam_receive

In some circumstances, as when inlining code, when some optimization
passes are disabled or with hand-written but semantically correct Core
Erlang or BEAM assembly, a fresh reference may be live in more than one
register:

    ...
    {allocate_zero,2,2}.
    ...
    {call_ext,0,{extfunc,erlang,make_ref,0}}. % Ref in [x0]
    ...
    {move,{x,0},{y,0}}. % Ref in [x0,y0]
    {move,{y,1},{x,0}}. % Ref in [y0]
    ...
    {move,{y,0},{x,0}}. % Ref in [x0,y0]
    {move,{x,0},{y,1}}. % Ref in [x0,y0,y1]
  {label,5}.
    {loop_rec,{f,6},{x,0}}. % Ref in [y0,y1]
    ...
    {loop_rec_end,{f,5}}.
  {label,6}.
    {wait,{f,5}}.
    ...

Pass beam_receive expects a single live register for the ref when it
encounters the loop_rec instruction and crashes with the following
reason:

$ erlc t.S
...
crash reason: {{case_clause,
                   {'EXIT',
                       {{case_clause,[{y,1},{y,0}]},
                        [{beam_receive,opt_recv,5,
                             [{file,"beam_receive.erl"},{line,154}]},
                         ...]}}},
               ...}

This commit teaches beam_receive how to use a set of registers instead
of a single one when tracking fresh references, thus avoiding the crash.

fix valgrind error in erts/emulator/drivers/unix/ttsl_drv.c

Running some valgrind memory checking showed the error below:

==18040== Thread 6:
==18040== Source and destination overlap in memcpy(0xf3f3f04, 0xf3f3f08, 52)

This occurred on Linux using R15B01 while the shell was emitting a prompt,
but the same problem is still present in R16B.

Change the memcpy on line 845 of ttsl_drv.c to memmove as valgrind
suggests. After the change, verify with valgrind that the error no longer
occurs.
