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.

2016-05-12time_SUITE: Make consistency/1 work in any timezoneBjörn Gustavsson
time_SUITE:consistency/1 would only work in CET, which was reasonable when the test suites were always run in Stockholm. Nowadays it is expected that you can run the test suite in any timezone. Therefore, only make sure that that difference between localtime/1 and universaltime/1 is "reasonable".

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.

2016-05-10erts: Implement max_heap_size process flagLukas Larsson
The max_heap_size process flag can be used to limit the growth of a process heap by killing it before it becomes too large to handle. It is possible to set the maximum using the `erl +hmax` option, `system_flag(max_heap_size, ...)`, `spawn_opt(Fun, [{max_heap_size, ...}])` and `process_flag(max_heap_size, ...)`. It is possible to configure the behaviour of the process when the maximum heap size is reached. The process may be sent an untrappable exit signal with reason kill and/or send an error_logger message with details on the process state. A new trace event called gc_max_heap_size is also triggered for the garbage_collection trace flag when the heap grows larger than the configured size. If kill and error_logger are disabled, it is still possible to see that the maximum has been reached by doing garbage collection tracing on the process. The heap size is defined as the sum of the heap memory that the process is currently using. This includes all generational heaps, the stack, any messages that are considered to be part of the heap and any extra memory the garbage collector may need during collection. In the current implementation this means that when a process is set using on_heap message queue data mode, the messages that are in the internal message queue are counted towards this value. For off_heap, only matched messages count towards the size of the heap. For mixed, it depends on race conditions within the VM whether a message is part of the heap or not. Below is an example run of the new behaviour: Eshell V8.0 (abort with ^G) 1> f(P),P = spawn_opt(fun() -> receive ok -> ok end end, [{max_heap_size, 512}]). <0.60.0> 2> erlang:trace(P, true, [garbage_collection, procs]). 1 3> [P ! lists:duplicate(M,M) || M <- lists:seq(1,15)],ok. ok 4> =ERROR REPORT==== 26-Apr-2016::16:25:10 === Process: <0.60.0> Context: maximum heap size reached Max heap size: 512 Total heap size: 723 Kill: true Error Logger: true GC Info: [{old_heap_block_size,0}, {heap_block_size,609}, {mbuf_size,145}, {recent_size,0}, {stack_size,9}, {old_heap_size,0}, {heap_size,211}, {bin_vheap_size,0}, {bin_vheap_block_size,46422}, {bin_old_vheap_size,0}, {bin_old_vheap_block_size,46422}] flush().

2016-04-15erts: Optimize tracer reload testLukas Larsson
Without off_heap message queue the GC of the tracer could take very long and thus delay the code:purge which would in turn allow the trace generator to generate a lot of more messages which would make the tracer GC for even longer etc etc. The time taken for the testcase could go up to as large as 10 seconds and use lots of memory.
