* josevalim/atu8-chunk/PR-1078/OTP-14178: Add new AtU8 beam chunk
2017-01-30Add new AtU8 beam chunkJosé Valim
The new chunk stores atoms encoded in UTF-8. beam_lib has also been modified to handle the new 'utf8_atoms' attribute while the 'atoms' attribute may be a missing chunk from now on. The binary_to_atom/2 BIF can now encode any utf8 binary with up to 255 characters. The list_to_atom/1 BIF can now accept codepoints higher than 255 with up to 255 characters (thanks to Björn Gustavsson).

2017-01-25erts: Remove broken hash from ErlangBjörn-Egil Dahlberg
erlang:hash/2 has been deprecated for a while, time to remove it.

2017-01-23erts: Fix binary_to_term for compressed and zlib >= v1.2.9Sverker Eriksson
Problem: z_stream was incorrectly copied with memcpy which just happened to work with zlib < v1.2.9. Solution: Avoid copying z_stream.

2017-01-13erts: Fix enif_send from noproc and no msg_envSverker Eriksson
Only try direct allocation on receiver heap when called in a real process context to avoid trylock on our own main lock.

2017-01-13Fix memory leak of temporary heapRickard Green
This bug was introduced in previous commit, and has never been released in an official OTP version.
2017-01-12erts: Add macro ERTS_PROC_LOCKS_HIGHER_THANSverker Eriksson
to safeguard against bugs due to future proc lock changes. The two places now using ERTS_PROC_LOCKS_HIGHER_THAN were kind of bugs as BTM and TRACE locks were missing. But there was probably no way to get there with BTM or TRACE locked.
2017-01-12erts: Cleanup enif_make_reverse_listSverker Eriksson
2017-01-12erts: Add assertions for correct ErlNifEnvSverker Eriksson

2017-01-12Return and exception trace for nif-export scheduled BIFsRickard Green
The support is somewhat primitive, since it is determined at call time if trace on return or exception should be sent.

* sverker/make-export-fun-race/OTP-14144: erts: Fix race bug between export fun creation and code loading
2017-01-12erts: Fix race bug between export fun creation and code loadingSverker Eriksson
Symptom: SEGV crash on ARM in delete_code() -> export_list(). Could probably happen on other machines as well. Problem: Staging export table was iterated in an unsafe way while an entry was added for a new export fun. Solution: Correct write order and some memory barriers.
