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.

Purpose: Prevent tricks to get hostile code running.

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.

This commit brings the perform of a non-strict equality check of
binaries into the same range as strict ones.
Currently, these checks can be significantly slower because they go
through the general comparison code which doesn't have an optimization
to check the size before comparing contents in the case that it's
checking equality.
