From https://tools.ietf.org/html/rfc7230#section-6.6
> A client that receives a "close" connection option MUST cease
sending requests on that connection and close the connection after
reading the response message containing the "close"; if additional
pipelined requests had been sent on the connection, the client
SHOULD NOT assume that they will be processed by the server.
Notes on tests:
* The new tests are added only in group sim_http and not sim_https
because the same test approach appears to be not valid because when
processing the first response the server already sent data (> 0) for
the TLS/SSL handshake;
* The order of tests is relevant as it appears some test cases leave
reusable sessions behind.

Remove note about heart rebooting on NTP updates

Check that messages outside of the heap are not corrupted

Waiting messages for a process may be stored in a queue
outside of any heap or heap fragment belonging to the process.
This is an optimization added in a recent major release to
avoid garbage collection messages again and again if there
is a long message queue.
Until such message has been matched and accepted by
the remove_message/0 instruction, the message must not be
included in the root set for a garbage collection, as that
would corrupt the message. The loop_rec/2 instruction explicitly
turns off garbage collection of the process as long messages
are being matched.
However, if the compiler were to put references to a message
outside of the heap in an Y register (on the stack) and there
happened to be a GC when the process had been scheduled out,
the message would be corrupted and the runtime system would
crash sooner or later.
To ensure that doesn't happen, teach beam_validator to check
for references on the stack to messages outside of the heap.

63e1c58d27ab (PR #1725) started to compile external funs
as literals.
This commit updates the dumping of literal areas to dump
external fun literals to the crash dump.

The server_node() function in the sample code was referring to messenger@bill, while the commands that follow use messenger@super as node name. Making both names consistent make it easier for newbies to test the code.

beam_record would make an unsafe optimization for the
not_used_p/4 function added to beam_utils_SUITE in this
commit. The bug is in beam_utils, which would falsely
report that {x,4} was unused when it in fact was used.
The bug was in the function not_used/1. The purpose of
not_used/1 is to return a 'not_used' result unless the
actual result is 'used'. Unfortunately it was not
implemented in that way. It would let a 'transparent'
result slip through, which the caller in this case would
convert to 'killed' (because the register was killed on
all other paths).

in state MON_FREE before it's initialized.
Still not really kosher to access 'state' without lock or atomic-op.

Compile external fun expressions to literals
OTP-15003

The expressions fun M:F/A, when all elements are literals are also
treated as a literal. Since they have consistent representation and
don't depend on the code currently loaded in the VM, this is safe.
This can provide significant performance improvements in code using such
functions extensively - a full function call to erlang:make_fun/3 is
replaced by a single move instruction and no register shuffling or
saving registers to stack is necessary. Additionally, compound data
types that contain such external functions as elements can be treated as
literals too.
The commit also changes the representation of external funs to be a
valid Erlang syntax and adds support for literal external funs to core
Erlang.

In the scenario where a gen_tcp:recv/2 detected an
error, the next gen_tcp:send should get a closed
error and not a enotconn error as was the case before.
