New MSG_SET command will be interpreted exactly as IPC_SET, but also will
update key, cuid and cgid values. IOW, it allows to change existent key value.
The fact, that key is not used is checked before update. Otherwise -EEXIST is

Stanislav Kinsbursky (9):
ipc: remove forced assignment of selected message
ipc: use key as id functionality for resource get system call introduced
ipc: segment key change helper introduced
ipc: add new SHM_SET command for sys_shmctl() call
This is a cleanup patch. The assignment is redundant.
