that uses its own super carrier (erts_exec_mmapper)
to guarantee low addressed and executable memory (PROT_EXEC).
Currently only used on x86_64 that needs low memory
for HiPE/AMD64's small code model.
By initializing erts_exec_mapper early we secure
its low memory area before erts_literal_mmapper might
steal it.

On MacOS X, defining _XOPEN_SOURCE usually *removes* features from
header files.
Therefore, we should not set _XOPEN_SOURCE to 600 since that will
remove the prototype for vsyslog(). Setting it to an empty value
or not including it will ensure that the vsyslog() prototype is
included.

Except it cannot be disabled and cannot be multi-threaded.
The bit-vector 'erts_literal_vspace_map' on 32-bit is currently only
protected by the literal allocator mutex. We could allow multiple
instances on 64-bit (I think), but what would be the point?

Fix the command line tools to abort on allocation failures when run
on Windows. Modify the malloc() wrapper to consistently return void*
across all the tools.

Fragmented young heap generation and off_heap_message_queue option
Refactor GC

* 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.

The "if" referred to in the comment was removed in commit 70c9312c4b.

`ct_run.c`, `erlc.c`, `escript.c` and `typer.c` do not preserve space characters in the emulator
path. Thus, if a path containing space is passed via environment variables, such as
`ESCRIPT_EMULATOR`, or if `get_default_emulator(progname)` returns a path with space, the execution
of the programs fail. This patch fixes all occurrences found with `grep push_words -R $ERL_TOP`.

The OSE port is no longer supported and this commit removed it
and any changes related to it. The things that were general
improvements have been left in the code.
