* 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.

* Measurements suggests that memcpy is a bit faster for small tuples
and ~50% faster for large tuples. (Linux kernel-3.2.0).

* ?line is not needed anymore and should be removed when
a test_SUITE is changed.

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.

* Don't redfine ALIGN_BITS or ALIGNED_SIZE, the global defined MSEG_*
constants are just as good.

To get a consistent naming scheme where
FBLK = Free block
ABLK = Allocated block
|
|
|
|
by making use of the new block header scheme to find the carrier header
and thereby the allocator.
|
|
Make use of type FreeBlkFtr_t
Rename GET_MB_CARRIER into BLK2MBC (like BLK2SBC)
Remove some unused macros
|
|
to allow realloc to determine block size (in MBC or SBC)
without having to read the footer of the previous block
that might be written to by concurrent thread.
