erts: Patch 1219
OTP-10602 Create an erl_crash.dump if no heart exists and no ERL_CRASH_DUMP_SECONDS
is set (behaviour changed). Don't create an erl_crash.dump
if heart do exists and no ERL_CRASH_DUMP_SECONDS is set
(behaviour not changed). This changes the behaviour back
to the R15B02 default considering if a beam was running
with no heart.

* Create an erl_crash.dump if no heart exists
and no ERL_CRASH_DUMP_SECONDS is set (behaviour changed)
* Don't create an erl_crash.dump if heart do exists
and no ERL_CRASH_DUMP_SECONDS is set (behaviour not changed)
This changes the behaviour back to the R15B02 default considering
if a beam was running with no heart.
The motivation is that we want a fast heart to fast restart erlang if
it crashes but to be able to get non-truncated erl_crash.dumps via
setting ERL_CRASH_DUMP_SECONDS if we so desire.

Also made check for DLL version against redistributables
instead of towards installed system, as some builds
required redistributables everytime (installed dll on build
machine had higher version than the redist)...

When erts_bs_append() calls the garbage collector, it has set
the PB_ACTIVE_WRITER flag in the ProcBin for the binary object
is about to be appended to. Therefore, it is expected that the
garbage collector should neither move nor shrink the binary
object.
But if the garbage collector does a minor collection (thereby
clearing the PB_ACTIVE_WRITER flag in the ProcBin) and there is
still not enough heap space, there will be a second major
garbage collection. During the major collection (since the
the PB_ACTIVE_WRITER flag was cleared), the binary object may
be shrunk or moved (depending on sizes and how many other
writable binaries there are in the process).
Avoid the problem by clearing the PB_ACTIVE_WRITER flags in
a separate pass after the garbage collection(s).
Thanks to Denis Titoruk for helping us find this bug.

- Teach lib/erl_interface/configure.in to look for
pthreads support in libc (where it can be found on QNX)
- A minor tweak such that this configure *fails* if you pass --enable-threads and
no pthreads support can be found.

Fix binary append exceptions
|
|
|
|
|
|
Code such as the following should cause an exception:
Bin = <<0:1>>,
<<Bin/binary,...>>
(Because the "binary" type implies that the binary must have a
size in bits that is a multiple of 8.)
Depending on the binary, either no exception was thrown or the
wrong exception was thrown (because c_p->freason was not set).

Not setting ERL_CRASH_DUMP_SECONDS will now terminate beam
immediately on a crash without writing a crash dump file.
Setting ERL_CRASH_DUMP_SECONDS to 0 will also terminate beam
immediately on a crash without writing a crash dump file, i.e. same as not
setting ERL_CRASH_DUMP_SECONDS environment variable.
Setting ERL_CRASH_DUMP_SECONDS to a negative value will let the beam wait
indefinitely on the crash dump file being written.
Setting ERL_CRASH_DUMP_SECONDS to a positive value will let the beam wait
that many seconds on the crash dump file being written.
A positive value will set both an alarm in beam AND a heart timeout for restart
if heart is running.
This is due to the change of 'heart' behavior when 'heart' is
listening for a crash.

When a crash dump is about to be written and we have
heartbeat enabled on a system. We need time to write it
before heart explicitly kills the beam.
