Crashdumps initiated by out-of-memory on spawn could cause the beam
to segfault during crashdump writing due to invalid pointers.
The pointers are invalid since the process creation never finished.
This commit remedies this problem by removing the process from
crashdump printout.

Clear the "enabled" flag for scheduling statistics when disable is
specified.

* rickard/+sfwi/OTP-11164:
erts: Add the +sfwi system flag
|
|
+sfwi Interval
Set scheduler forced wakeup interval. All run queues will be scanned
each Interval milliseconds. While there are sleeping schedulers in
the system, one scheduler will be woken for each non-empty run queue
found. An Interval of zero disables this feature, which also is the
default.
This feature has been introduced as a temporary workaround for lengthy
executing native code, and native code that do not bump reductions
properly in OTP. When these bugs have be fixed the +sfwi flag will
be removed.

Rewrite and extend of Happi's initial work
Extra_root to process structure to enable GC of state - Changed the
process structure to point to a separate struct, the struct also
contains a destructor function to allow for proper cleanup.
Rewrote encode_size_struct and enc_term to have internal versions with
reduction counters which will result in interrupt for later restart
when the counter reaches zero - removed the EWA_STACK from Happis
version and directly save the ESTACK's and WSTACK's in the above
mentioned struct (or array thereof) that are pointed out from the
process structure. The destructor will take care of the deallocation
in case of process death.
Added ESTACK and WSTACK macros to save and restore stack and to change
allocator, which makes the previously mentioned stack-save work.
Rewrote enc_term to not store pointers on the stack, and use one WSTACK
for commands etc and another ESTACK for Eterms - Slightly different than
Happis version to make halfword code simpler.
Rewrote encode_size_struct2 so that it does not store pointers on the
stack, also switched to ESTACK instead of WSTACK, this also handles
halfword correctly.
Added interfaces for chunkwise compression, that are
used from term_to_binary/2 when the compressed option is given.

Functionality for scheduling operations at thread progress later
has been introduced.
Deallocation of ETS table structures were previously done by scheduling
misc aux work. Deallocation of process structures (not released yet)
was also implemented this way. Instead of using the misc aux work
functionality these implementation now use the newly introduced
functionality for scheduling operations at thread progress later. By
using this new functionaliy we reduce the amount of memory
allocation/deallocation operations needed.
