2016-08-12erts: Align ErtsThrPrgrLaterOp when free'ing tracerLukas Larsson
On Sparc all structs with a double word element in are assumed to be allocated on a two word boundary. So we have to make sure that the ErtsThrPrgrLaterOp * points to 8 / 16 byte aligned memory. As it only costs one word I've done it on all architectures in case some unknown other arch also needs this.

2016-08-12erts/kernel: Fix code loading deadlock during init:stopLukas Larsson
When init:stop is called it walks the application hierarchy and terminates each process. Some of these processes may do something while terminating and sometimes that something needs to load some new code in order to work. When this happens the code_server could just be in the process of terminating or the erl_prim_loader could be active. In both these cases the request to load the new code would cause a deadlock in the termination of the system. This commit fixes this by init rejecting attempts to load new code when init:stop has been called and fixing a termination race in the code_server. This however means that the process that tried to do something when told to terminate (for instance logging that it is terminating) will crash instead of loading the code.

2016-07-21erts: Fix internal hashing entropy for mapsBjörn-Egil Dahlberg
We need to use an initial hash seed for each map pair, i.e. the hash value. The hash value is reset to the seed for each pair instead of setting the seed to zero. If we don't, no additional entropy is given to the system and the hash collision resolution in maps:from_list/1 would fail.
