Currently, in sys:stat/2, the message out only count for system events with format
{out, Msg, To}. However, the gen_server:reply/5 will call sys:handle_debug/4
with format {out, Reply, To, State}. That will make the message out count fail
to pattern matching.
Also update sys_SUITE.erl and relevant docs.

This commit replaces the old memory instrumentation with a new
implementation that scans carriers instead of wrapping
erts_alloc/erts_free. The old implementation could not extract
information without halting the emulator, had considerable runtime
overhead, and the memory maps it produced were noisy and lacked
critical information.
Since the new implementation walks through existing data structures
there's no longer a need to start the emulator with special flags to
get information about carrier utilization/fragmentation. Memory
fragmentation is also easier to diagnose as it's presented on a
per-carrier basis which eliminates the need to account for "holes"
between mmap segments.
To help track allocations, each allocation can now be tagged with
what it is and who allocated it at the cost of one extra word per
allocation. This is controlled on a per-allocator basis with the
+M<S>atags option, and is enabled by default for binary_alloc and
driver_alloc (which is also used by NIFs).

Compiling OTP-20.3.4 with GCC-7 generates the following warning:
CC /tmp/otp_src_20.3.4/lib/erl_interface/obj.st/x86_64-unknown-linux-gnu/erl_marshal.o
legacy/erl_marshal.c: In function 'erl_init_marshal':
legacy/erl_marshal.c:110:5: warning: 'memset' used with length equal to number of elements without multiplication by element size [-Wmemset-elt-size]
memset(cmp_array, 0, CMP_ARRAY_SIZE);
^~~~~~
CMP_ARRAY_SIZE (256) is the number of elements in that array, but the
elements are not char but enum, which is 4 bytes on e.g. x86-64.
This results in 3/4 of the array not being correctly initialized.
Idiomatic C is to pass sizeof cmp_array to memset(), so that's what I did.

Sending a large term to the error logger has two problems related
to the size and sign of the variables used to represent lengths:
- the API functions (erts_send_error_term_to_logger() et al) perform
an unchecked narrowing conversion from size_t to int when passing
dsbufp->str_len to the internal functions; this may both truncate
the length and make it negative
- do_send_term_to_logger() and do_send_to_logger() multiply the
int-typed length by 2 before widening it to Uint and adding a few
more values; the intermediate product may overflow causing loss
of high bits and a change of sign; if the intermediate product is
negative the final size will be an extremely large positive value
The end result is that the computed buffer size can be arbitrarily
wrong, either too small or too large.
While reviewing this code I also found and fixed a potential narrowing
bug in erts_set_hole_marker().

and not the name. For more sane named table semantics.
Applies to both select/1 continuation and trap context.

where argument 'list' is the first candidate (not list->next).
Also simplified db_first_hash().

There is no NULL check here !?

and instead test for mprotect which is what is uses.
The use of MAP_NORESERVE for hipe code allocations
was removed in 8fd6e3353b094aa94e37e257ee20cd5e0e5dddcb.

proc->run_queue detected as uninitialized by valgrind
but seems harmless in practice as it's not used for proxy processes.
"Bug" introduced in OTP-17 by ca0425c6ff85262bc15367f5fd9cbc51cde52b20
and made worse (but still harmless) in master for OTP-21
at fbb10ebc4a37555c7ea7f99e14286d862993976a.
