* sverk/hamt-overestimate/OTP-12585:
erts: Add test map_SUITE:t_hashmap_balance
erts: Fix hashmap overestimation
erts: Silence valgrind warning in nif_SUITE.c

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 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.

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.

This commit introduces two BIFs:
* erts_internal:map_type/1
* erts_internal:map_hashmap_children/1
erts_internal:map_hashmap_children/1 is only intended for use within
erts_debug:size/1 since the internal hashmap node is not allowed to
leak anywhere.
