move memset to memutil

use string identifiers for events ...

(some rework of the string saving system was required)

use stringmap for communication between processes

use saved strings for service interaction system calls

add read string syscall

add stringmap insert and read length functions

mov syscall handlers to different files

seperate log into log file and a parallel driver
