2018-04-23erts: Rewrite memory instrumentationJohn Högberg
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).

2018-04-21erl_interface: fix bad memsetMikael Pettersson
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.
2018-04-21fix integer truncation bugs in error logger pathMikael Pettersson
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().
2018-04-20erts: Use table ref for select continuationSverker Eriksson
and not the name. For more sane named table semantics. Applies to both select/1 continuation and trap context.
2018-04-20erts: Refactor erl_db_hash next() into next_live()Sverker Eriksson
where argument 'list' is the first candidate (not list->next). Also simplified db_first_hash().

2018-04-20erts: Fix run queue pointer in proxy processSverker Eriksson
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.
