Allow multiple modifier characters in io:format control sequences OTP-14971

This makes it possible to print unicode atoms at the same time as suppressing detection of printable lists.
2018-03-10make erlang:process_info/1 not retrieve messagesMikael Pettersson
process_info/1 retrieves a number of properties related to a process, including the list of messages in its mailbox. This is potentially unsafe if the target process has a large number of queued messages: - there is no a priori upper bound on the amount of memory being allocated to hold that list, and - the loop to retrieve the messages is uninterruptible, so the Erlang scheduler where this executes blocks for the duration We've seen process_info/1 bring down heavily loaded nodes on more than one occasion. At least once it appeared to have blocked the Erlang heart process from executing, causing the external heart to kill the VM. Consequently this removes 'messages' from the list of process_info tags to retrieve for process_info/1. Note that process_info/1 still retrieves 'message_queue_len', and process_info/2 can still retrieve 'messages' when asked to. A few places in the OTP libraries need minor adjustments, since they want 'message_queue_len' but compute it from the length of the list of messages.

Optimization does not trigger for try-catch. But send cannot fail here anyway, as Process cannot be an atom.

as workarounds to avoid blocking auto-connect, which is now asynchronous in OTP-21. Also changed old catch to more efficient try-catch.

as fallback when erlang:monitor failed toward primitive nodes, which it does not do in OTP-21.

The small sub-binary conversion trick in the GC broke this test pretty often on some machines.
2018-02-26Replace binary:bin_to_list CIF implementation with binary_to_listJohn Högberg
binary:bin_to_list had a poor implementation that resulted in excessive garbage collection. binary_to_list is almost identical and has a generally better implementation, so I've replaced binary:bin_to_list's CIF with a thin wrapper around binary_to_list. Granted, binary_to_list has a deprecated indexing scheme, but we're unlikely to ever remote it entirely and it's somewhat easy to move it to the 'binary' module later on.
