Run-time tested with FreeRTOS V8.1.2 (current version).
For the time being I propose this way of dealing with RTOSes that do
not export necessary information on their own.
I also suggest implementing a similar scheme for ChibiOS, exporting
the necessary struct fields' offsets via an OpenOCD-specific helper.

Each RTOS implementation uses it's own (similar) code to free
the thread list. There are some additional issues:
<--->
if (pointer != NULL)
free(pointer);
<--->
This is not necessary, free(NULL) is perfectly ok.
<--->
free(rtos->thread_details);
rtos->thread_details = NULL;
rtos->thread_count = 0;
<--->
The 3rd line has been missing for all RTOS but ChibiOs. There are paths
in the code where rtos->thread_count is never set to NULL, which can
lead to null pointer dereference of rtos->thread_details.
