Processes remember heap fragments that are known to be fully
live due to creation in a just called BIF that yields in the
live_hf_end field. This field must not be used if we have not
disabled GC in a BIF. F_DELAY_GC has been introduced in order
to distinguish between to two different scenarios.
- F_DISABLE_GC should *only* be used by BIFs. This when
the BIF needs to yield while preventig a GC.
- F_DELAY_GC should only be used when GC is temporarily
disabled while the process is scheduled. A process must
not be scheduled out while F_DELAY_GC is set.

The TMPBUF option is no longer needed due to is_literal test and NONE
was only used for initial debugging. So we remove the entire option.

This is very verbose, you have been warned.
It should work with the copy-spy.py script, which may be a bit outdated.

* The youngest generation of the heap can now consist of multiple
blocks. Heap fragments and message fragments are added to the
youngest generation when needed without triggering a GC. After
a GC the youngest generation is contained in one single block.
* The off_heap_message_queue process flag has been added. When
enabled all message data in the queue is kept off heap. When
a message is selected from the queue, the message fragment (or
heap fragment) containing the actual message is attached to the
youngest generation. Messages stored off heap is not part of GC.

Not needed as it is always set to erts_this_dist_entry (on net_kernel).

Binary vheap mature is not necessary for binary gc.

Lots of pthread platforms unnecessarily falled back on the pipe/select
solution. This since we tried to use the same monotonic clock source
for pthread_cond_timedwait() as used by OS monotonic time. This has
been fixed on most platforms by using another clock source.
Darwin can however not use pthread_cond_timedwait() with monotonic
clock source and has to use the pipe/select solution. On darwin we
now use select with _DARWIN_UNLIMITED_SELECT in order to be able to
handle a large amount of file descriptors.

Teach smp VM how to deal with crash of a linked trace port

* sverk/smp-trace-port-exit-bug/OTP-12901:
Teach smp VM how to deal with crash of a linked trace port
|
|
Problem: The sys-msg-dispather crashes the VM when trying to send
exit signals from the links of the terminating trace port.
If try-lock of the linked process fails, a pending exit is
scheduled and erts_scheduler_data() is then called to find
"my" run queue. But sys-msg-dispatcher is not a scheduler
and has no scheduler data, hence SEGV.
Fix: If not a scheduler and we cannot get process locks,
schedule process in its previous run-queue.

The OSE port is no longer supported and this commit removed it

improvements have been left in the code.

All flags was not always set when setting multiple aux work
flags at once. This scenario is fortunately quite uncommon
and only caused further delay in memory deallocations.
