The thread monitor allows to iterate over the thread context
structures for each existing thread (fiber/task) in the system.
Thread context structures do not expose thread entry information
directly. Although all the information can be scavenged from memory
stacks. Besides, accessing the information depends on the stack
implementation for each architecture.
By extending the tcs we allow a direct access to the thread
entry point and its parameters, only when thread monitor is
enabled.
It also allows a task to access its kernel task structure
through the first parameter of the thread.
This allows a debugger application to access the information directly
from the thread context structures list.
