This fixes a fault introduced in 19.0 where an invalid
tracer would block setting of a new tracer on a process.

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.

We have to do an extra check if the return_to trace is enabled here
as it may have been cleared by the bif after the flags where
created by the call_trace.
|
|
Because check_process_code neglected checking the HiPE stack for
references to the literal area, such references would survive the purge
and subsequent deletion of a module and its literal area. These dangling
references would then cause incorrect behaviour or even hard crashes of
the VM.
By simply adding a scan of the HiPE stack to check_process_code and
erts_garbage_collect_literals, this problem is fixed.
In order to support full stack walks without deleting the graylimit
trap, a new stack walking interface function,
nstack_walk_init_sdesc_ignore_trap() was introduced.

This makes the time that the tests execute longer, which means
that on systems with low resolution on timers (e.g. windows)
the test is less likely to fail.
|
|
The granualarity of the windows time sometimes makes timer:tc
return 0 as the time taken for the test. Change this to use
the most common time instead.

if node fails to start, just skip testcase

It has to be possible to send trace messages to a port
from non-schedulers threads (specifically from the
sys_msg_dispatcher).
