2019-03-25erts: Yield when exiting/free process is suspended by deLukas Larsson

2019-03-25erts: Include external msg in need of GCLukas Larsson
When many external messages suddenly appear in the mailbox the young gen size is adjusted accordingly but it was immediately shrunk as the data was not counted towards the shrink size. This commit includes the ext dist size in the shrink calculation which means that the decode of the external messages will not trigger as many GCs which means much better performance.
2019-03-25erts: Include dist header in return from dist_ctrl_get_dataLukas Larsson
2019-03-25erts: Fix so that exit/down terms stay aliveLukas Larsson
When the GC is run or the link/monitor node is deleted, the terms associated with it will also be deallocated so we have to make sure that we don't do any GCs and that all link/monitor nodes are copied onto the heap before the node is deallocated.
2019-03-25erts: Pending signals can be for free processesLukas Larsson
Since we no schedule free processes multiple times, pending signals can be from free as well as current processes.
2019-03-25erts: Fix faulty assert in reference_table_termLukas Larsson
2019-03-25etp: Don't crash etp-stack* when c_p->i is nullLukas Larsson
2019-03-25erts: Adjust dist obuf size correctly after hdr finLukas Larsson
2019-03-25erts: Fix non-payload dist exit signalsLukas Larsson
When interacting with jinterface and erl_interface the old dist messages are used and they incorrectly used the external data.
2019-03-25erts: Always do trylock on proc locks when crash dumpingLukas Larsson
2019-03-25Fix tests to work better in debug emulatorLukas Larsson
2019-03-25erts: erts_factory_proc_init should not set hole markerLukas Larsson
Setting the hole marker in debug on the entire heap is very slow so instead we do it in erts_produce_heap.
2019-03-25erts: Skip heavy process tab tests in debug emuLukas Larsson
2019-03-25Revert "erts: Always run fds check after each testcase"Lukas Larsson
This reverts commit 1eb0a2c47edd036731ee1e4e4f7b5bdfc7d576fa.
2019-03-25erts: Always run fds check after each testcaseLukas Larsson
2019-03-25erts: Always stop any testnodes before testcase exitsLukas Larsson
This needs to be done in order for automatic fd leak checking to work properly.
2019-03-25erts: Add crash dumping of EXITING and FREE processesLukas Larsson

2019-03-25erts: Fix file desc leak in poll debug get_evtsLukas Larsson
2019-03-25erts: Fix verify_nc in distribution suiteLukas Larsson
When the calling process is trapping exits a stray message will end up in the mailbox which is problematic. This change uses a monitor instead.
2019-03-25erts: Fix atom16 testcase after dist frag implLukas Larsson
2019-03-25erts: Fix make system to pass TYPE from top levelLukas Larsson
This makes it possible to do: make release TYPE=debug from ERL_TOP and it will build the correct things.

2019-03-22beam_emu.c: Avoid triggering an assertion for the wrong reasonBjörn Gustavsson
Before 2d2e78ad6e66 that introduced tail-recursive calls of BIFs, the stack was guaranteed not to be empty when `erlang:raise/3` was called from the `catch` block of a `try` (because the `try` had set up a stack frame that would be deallocated after the `raise` call). Now the stack can be empty, so the ASSERT() call in next_catch() that checks that there is a continuation pointer at the top of the stack may fail. Move the ASSERT() call to after check for empty stack. While at it, also add a comment of the reason for the assertion.

2019-03-22erts: Fix incorrect UNC path length calculationJohn Högberg
This didn't cause any issues for the most part since the path was still properly formed, but it broke down when appending the wildcards in file:list_dir/1. The ASSERT_PATH_FORMAT macro would have caught this in no time, but it went unnoticed because we don't run debug builds on Windows.
