* 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

* rickard/off_heap-nonsmp-fix/OTP-13366:
Do not send on_heap msgs to error logger in non-smp emulator

|
* rickard/mv-dirty-reds-count/OTP-13123:
Move dirty reduction count to erts_dirty_process_main()
|

* vinoski/dirty_process_main/OTP-13123:
Add dirty_process_main function
|
|
|
|
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.

and replace with a nice else-if chain.

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.

Remove the 'message_queue_data' option 'mixed'

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.

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.

* egil/erts/fix-purge_code-literals:
erts: Refactor ERTS_MSG_COMBINED_HFRAG to heap fragment
erts: Copy literals in messages on module purge
erts: Add testcase for purge of literals
|
|
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.

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.

This merge is actually only some left overs.
The bulk work for hipe-amd64-code-alloc has already been
merge (without ticket number) at 42a1166b47721cd444.

* mikpe/otp-19-erts-integer-truncation-bugs/PR-1045/OTP-13606:
erl_unicode.c: fix integer truncation problems

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.

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.

- Modify trace flags of process...
- Process info on process...
- Register/unregister of name on process...
- Set group leader on process...

* Add the capability to format erlang terms to a char buffer in nifs.
* Bump NIF version to 2.11
