This does not avoid allocating a ProcBin since we still need to
release the binary somehow (and using the tmp obj list is slightly
slower since it's an unavoidable off-heap allocation), but it does give
us a hard limit on how long said ProcBin will live, which is a lot
better than before.

When fixing OTP-14931/14932 we had to settle for a solution that
decreased performance in a few corner cases like multiple calls to
enif_make_binary, as the other options on the table required extra
fields which would have broken ABI compatibility.
This is ABI-compatible since the fields are unused and at the end.
|
|
This fixes two corner-cases:
1) We will no longer return an invalid term when a binary inspected
on environment A is used in enif_make_binary on environment B
2) A double-free in this sequence of events:
* enif_alloc_binary(size, &bin);
* enif_ioq_enq_binary(ioq, &bin, skip);
* enif_make_binary(env, &bin);
* enif_make_binary(env, &bin);

Attaching to a ProcBin is the fastest way to delay the release of an
already allocated Binary, but alloc_tmp_obj is a lot faster when
starting from scratch since it usually uses temp_alloc.

Do destructive write of immed value if key exists.
This is an optimization at the expense of get/0
which must now copy all (mutable) key-value tuples.

Exclude garbing processes, EXCEPT if run by crash dumping thread
in which case we assume the heap is healthy
without any move markers yet/left.
Switched order between (allocating) setup_rootset()
and (move marking) collect_live_heap_frags().

When supplied without an enclosing list, bitstrings were returned
as-is instead of badarging.

A binary is a binary as long as its size in bits is evenly divisible
by 8, regardless of whether it has a bit offset or not.
|
|
When supplied without an enclosing list, bitstrings were silently
truncated to [] instead of badarging.
|
|
This has always worked but we lacked test coverage for it.

Huge inputs weren't particularly useful and took forever to run, so
this commit winds it down to a more sane level that still causes
lots of yielding.

fmt_double() may write up to 8 characters into its format_str[]
buffer, which however only has room for 7 characters.
This case could be triggered by a call to erts_printf_format() with
any floating-point format that also includes #, and + or a space,
which may be uncommon, but a nif or driver could issue it.

In preparation for carrier age order.
Change 'flavor' to 'blk_order' and 'crr_order'.
