Ensure that we cannot get any dangling pointers into code that
has been purged. This is done by a two phase purge. At first
phase all fun entries pointing into the code to purge are marked
for purge. All processes trying to call these funs will be suspended
and by this we avoid getting new direct references into the code.
When all processes has been checked, these processes are resumed.
The new purge strategy now also completely ignore the existence of
indirect references to the code (funs). If such exist, they will
cause bad fun exceptions to the caller, but will not prevent a
soft purge or cause a kill of a process having such live references
during a hard purge. This since it is impossible to give any
guarantees that no processes in the system have such indirect
references. Even when the system is completely clean from such
references, new ones can appear via distribution and/or disk.

erts: Align ErtsThrPrgrLaterOp when free'ing tracer
|
|
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.

erts/kernel: Fix code loading deadlock during init:stop
|
|
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.

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.
