Also, it fixes test to work with new IPC sysctls (instead of using

Currently, this is not true, because timer
, it will be dropped to zero and
-EAGAIN will be returned to user.
Hash table is size of page (4KB).
Key is constructed as follows:
key = hash_ptr(current->signal) ^ hash_32(posix_timer_id);

The reason for shit patch is that SET_SET is desired to be a part of new part
of API of IPC sys_semctl() system call.
The name itself for IPC is quite natural, because all linux-specific commands
names for IPC system calls are originally created by replacing "IPC_" part by
"SEM_"("MSG_", "SHM_")
the queue).
Notes:
1) Return -ENOSYS if MSG_COPY is specified, but CONFIG_CHECKPOINT_RESTORE is
not set.

This patch moves all message related manipulation into one function msg_fill().
Actually, two functions because of the compat one.

er problem was to peek messages from queues without deleting them.
This was achived by introducing of new MSG_COPY flag for sys_msgrcv(). If
MSG_COPY flag is set, then msgtyp is interpreted as message number.
The following series implements...

New SHM_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
returned.
