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.

The code itself is backwards compatible with OTP 17, since development is still largely based on 17. Updates for the new time api in OTP 18 were merged into maint in commit 5e5b2221, and on to master in commit ebf24297. Conflicts: lib/diameter/src/base/diameter_lib.erl

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.

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.

2015-03-19hipe: Handle separate hashmap tag correctlySverker Eriksson
This is a temporary fix, it's probably a better solution to combine into one header tag for both map types.
2015-03-19erts: Fix map bug in dec_term for 32-bit debug VMSverker Eriksson
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.
