1. SMP: Fix an assertion. SMP-specific change accidentally made in non-SMP code
...
2. Move list of signal actions from the task TCB to the task group. Signal handlers are a property of the entire task group and not of individual threads in the group. I know, I preferred it the other way too but this is more compliant with POSIX.
