Enable thread analyzer functionality and all the required modules.

This module may be used to debug thread configuration issues, e.g.

stack size configuration to find stack overflow or to find stacks

The thread analysis takes quite a long time.
|
|
Every thread it finds is analyzed word by word to find any that
|
|
does not match the magic number.
|
|
Normally while thread are analyzed the k_thread_foreach function
|
|
is used.
|
|
While this is a safe run from the thread list perspective it may lock
|
|
the interrupts for a long time - long enough to disconnect when
|
|
Bluetooth communication is used.
|
|
Setting this flag will force thread analyzer to use
|
|
the k_thread_foreach_unlocked function.
|
|
This will allow the interrupts to be processed while the thread is
|
|
analyzed.
|
|
For the limitation of such configuration see the k_thread_foreach
|
|
documentation.
