free the system call structure of a crashed system call process

add system call to look up the names of functions

add basic stack tracing ability

notify other tasks of a exception happening ...

subscribe to the interrupt 0 to be notified about exceptions

gracefully handle crashes of a user mode programm

fix interrupts occuring while in user mode

now matches the documentation in the wiki

add kernel events ...

kernel events get triggered by the kernel when certain things happen.

add an additional argument to request calls

use string identifiers for events ...

(some rework of the string saving system was required)

print a message when a key is pressed

enable subscribing to an interrupt and set up the PIC

end tasks when they trigger an exception

enable interrupts
