Changed the way user/kernel time is tracked for threads. Now, thread_at_kernel_entry()

Browse Source 
and thread_at_kernel_exit() are always called for userland threads at the appropriate
situation (note, I've renamed those from *_atkernel_*).
The timing should be more accurate this way, and the thread::last_time_type field
is no longer needed: all interrupts are now added to the kernel time (where the
time is actually spent).
