Observer makes use of cdv_html_wx but does not start cdv_wx first which
made it crash when trying to send a message to cdv_wx. This fix avoids
updating the status when the application using cdv_html_wx is cdv.

Similar bug as for bxor fixed by abc4fd372d476821448dfb9
Ex:
1> io:format("~.16B\n", [-16#1110000000000000000 band (-1)]).
-1120000000000000000
Wrong result for
(-X bsl WS) band -Y.
where
X is any positive integer
WS is erlang:system_info(wordsize)*8*N where N is 1 or larger
Y is any positive integer smaller than (1 bsl WS)
Fix:
The subtraction of 1 (for 2-complement conversion)
must be carried along all the way to the last words.

Due to comparison as a signed integer, when getting an unsigned atomic
in the range 2^63-1..2^64-1 (when the most significant bit was set), the
heap could get corrupted when the integer was retrieved: hsz would get
set to zero, but the code proceeded to build a bignum.
Steps to reproduce (at least on x86_64):
$ erl
1> A = atomics:new(1,[{signed,false}]).
2> atomics:put(A,1,18446744073709551615).
3> atomics:get(A,1).
At the last step, the shell would print some garbage and hang.

As the stop wrapper functions are no longer needed after tls_sender
that altered the behaviour of the TLS distribution code.
|
|
Both test case and code needed updates to work as intended. Code needed update due to
new tls_sender process and the test case gave false positive reusult erarlier probably
due to beeing to sloopy in order to avoid timeouts.

Fix reading beyond end of bignum in integer squaring
|
|
The multiplication of two bignums is specially optimized when the two
operands have the same address, because squaring can be done more
efficiently than multiplication of two arbitrary integers. That is,
expressions such as `I * I` will be calculated by squaring the value
of `I`.
The optimized function for squaring would read one word beyond the
end of the bignum in the last iteration of a loop. The garbage
value would never be used. In almost all circumstances that would
be harmless. Only if the read word happened to fall on the start
of an unmapped page would the runtime crash. That is unlikely
to happen because most bignums are stored on a process heap, and
since the stack is located at the other end of the block that the
heap is located in, the word beyond the end of bignum is guaranteed
to be readable.

Without this fix asserts would trigger in debug build
but nothing else would break.

The example should not show the iterator as that is
an internal value and if changed can confuse the reader
of the documentation. See ERL-796

At start of the VM a poll-set that the schedulers
will check is created where fds that have triggered
many (at the moment, many means 10) times without
being deselected inbetween. In this scheduler specific
poll-set fds do not use ONESHOT, which means that the
number of syscalls goes down dramatically for such fds.
This pollset is introduced in order to handle fds that
are used by the erlang distribution and that never
change their state from {active, true}.
This pollset only handles ready_input events,
ready_output is still handled by the poll threads.
During overload, polling the scheduler poll-set is done
on a 10ms timer.
