This will also fix a bug in term_to_binary treating full nodes as tuples and emiting LIST_EXT for leafs.

Must save hamt_list in context.
2015-03-24erts: Fix comparison of exact termsBjörn-Egil Dahlberg
Comparison of exact terms could cause faulty term tests. This was caused by a faulty (too small) internal type. Symptom: -1 = erts_internal:cmp_term(2147483648,0). %% wrong Correct: 1 = erts_internal:cmp_term(2147483648,0). Reported-by: Jesper Louis Andersen

2015-03-20erts: Fix hashmap overestimationSverker Eriksson
Old overestimation assumed an average of k/3 nodes. This can be bad for large maps (with tight standard deviations) as the average vary between 0.3*k and up to almost 0.4*k.

2015-03-20Implement ethread events with timeoutRickard Green
2015-03-20Introduce a new time APIRickard Green
The old time API is based on erlang:now/0. The major issue with erlang:now/0 is that it was intended to be used for so many unrelated things. This tied these unrelated operations together and unnecessarily caused performance, scalability as well as accuracy, and precision issues for operations that do not need to have such issues. The new API spreads different functionality over multiple functions in order to improve on this. The new API consists of a number of new BIFs: - erlang:convert_time_unit/3 - erlang:monotonic_time/0 - erlang:monotonic_time/1 - erlang:system_time/0 - erlang:system_time/1 - erlang:time_offset/0 - erlang:time_offset/1 - erlang:timestamp/0 - erlang:unique_integer/0 - erlang:unique_integer/1 - os:system_time/0 - os:system_time/1 and a number of extensions of existing BIFs: - erlang:monitor(time_offset, clock_service) - erlang:system_flag(time_offset, finalize) - erlang:system_info(os_monotonic_time_source) - erlang:system_info(time_offset) - erlang:system_info(time_warp_mode) - erlang:system_info(time_correction) - erlang:system_info(start_time) See the "Time and Time Correction in Erlang" chapter of the ERTS User's Guide for more information.

* nox/fix-port_info-race: Fix a race condition when calling port_info/1 OTP-12587
2015-03-19erts: Silence valgrind warning in nif_SUITE.cSverker Eriksson
Hmm, seems like gcc (4.4.3 at least) can switch the order of an &&-expression and do the last condition first if it think it's more efficient (and without side effects I hope). Which led to valgrind complaining about 'prev_ret' being used uninitialized in this case.

The [ew]default field would get uninitialised when the stack was saved and later restored. Detected by valgrind.

Adding ERTS_SWORD_MAX to a pointer does not work as a way to disable a bound check. Remove the hp_end from ErtsHeapFactory as it isn't really used anyway.
