2016-06-10erts: Add port monitorsDmytro Lytovchenko
* erlang:monitor/2 with port argument is added, erlang:demonitor, using port task API and avoiding locking; * port_info and process_info support for monitored ports (with named port monitors support); * Exit signals contain type 'process' or 'port'; * Propagation of port exit signals; * Self-cleaning when origin process dies with monitor on; * 8 test cases + testcase for port driver crashing; * Documentation for all of the above (monitor, demonitor, port_info and process_info) updated

2016-05-31Move dirty reduction count to erts_dirty_process_main()Rickard Green
2016-05-31Add dirty_process_main functionSteve Vinoski
Dirty schedulers only execute NIFs, so having them execute the full process_main function isn't necessary. Add dirty_process_main for dirty schedulers to execute instead. Add erts_pre_dirty_nif(), called when preparing to execute a dirty nif. Add more dirty NIF tests to verify that activities requiring the process main lock can succeed when the process is executing a dirty NIF.

2016-05-30erts: Fix ASSERT provoked by map_SUITE:t_rare_map_overflowSverker Eriksson
The same bug was fixed for OTP 18 in cb62c989e59f0ec8556f9f1d4e9a45b by provoking yet another GC. But now in 19 we are ok with heap fragments so just remove the asserts.

2016-05-27erts: Split large binaries into multiple iovecLukas Larsson
On windows the max size of an iov element is long, i.e. 4GB so in order to write larger binaries to file we split the binary into smaller 2GB chunks so that the write is possible.

2016-05-26erts: Improve some bad hash functionsSverker Eriksson
Multiplying two atoms will always yield the same low 6 bits. The most important tabke 'export' was saved by the prime number table size which seemed to yield a decent uniform distribution anyway.

2016-05-24erts: Move tracer SecondTraceTerm to Opts mapLukas Larsson
The extra trace data has been moved to the opts map in order for the tracer to be able to distinguish inbetween extra trace data 'undefined' and no extra trace data. In the same commit all opts associations have been changed so that if the tracer should not use them, the key is left unassicated instead of being sent to undefined. This should be give a small performance gain and also makes the API easier to work with.

2016-05-20erts: Copy literals in messages on module purgeBjörn-Egil Dahlberg
During check process code, explicitly copy all referenced literals in a message (in the private queue) to a heap fragment and attach it to the message reference. Not all types of message communication does an explicit copy of a literal and this needs to be taken care of before a module is purged.

2016-05-17erts: Fix OpenBSD gcc compiler bug in re codeLukas Larsson
The OpenBSD 5.8 gcc compiler emits erroneous code which results in the re:run function behaving badly, though strangely enough it does not segfault the vm. This fix moves code around a bit in order to make gcc emit correct code.

2016-05-11erts: Only allow remove from trace_status callbackLukas Larsson
Make it so that it is only possible to remove a tracer via returning remove from an erl_tracer. This limition is put in place in order to avoid a lot of lock checking and taking in various places, especially in regards to trace events happening on dirty schedulers.
