- use one single library instead of loose library files
- we don't have ftime() anymore
- shmat(non-NULL) is currently broken, fix shmt test set to bypass this
- some other small issues
. rename testshm.sh to test.sh so all test scripts are called test.sh
. delete msg* tests as msg* functionality isn't implemented
. add ipc/test.sh that runs all test.sh scripts in the subdirs
