Replace heave array_put() with a dumb array index assignment ARRAY_PUT
and instead introduce ensure_array_size() to be called when
we know the array might need to grow.
This change also ensures the entire HASH_RANGE is always
allocated. No need for ARRAY_GET to check index any more.

by limiting table sizes to powers of 2.
This will change the default size from 10 to 8.

The message_queue_data option can have the values
- off_heap
- on_heap
- mixed
|
|
|

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.

Make sure a heap fragment is not deallocated before all off_heap
terms have been cleared.
The fix assumes/asserts that the off_heap-lists of all additional
heap fragments are empty.
I think this bug has been harmless as hashmap nodes, which is only
ones (?) that can cause a factory to produce more heap,
are not linked in off_heap-list.

ERTS_PRINT_INVALID prevented file descriptor 0 to be used which
could cause an empty crash dump.

Note that hash.c is quite "clean" from Erlang stuff
and is used by erl_child_setup as well.

1. Use load factor as indicator, not used buckets.
Used buckets is a bad indicator as it makes the situation even
worse with a bad hash function.
Set grow_threshold to load factor of 160% as it roughly corresponds
to the old 80% used bucket limit.
2. Never shrink table below initial size.

Can only be caused by distributed messages containing large maps.
Bad map hashing will increase the risk.

That double free is probably very seldom invoked as the port is already
gone leading to free_data being called instead of file_async_ready.
