64bit sysv ipc code

[Vasim Valejev]

Hi !

I've made full patch to allow allocate blocks >1G size as SYSV's shared memory
(including that compilation warning fix) and attached to this message. This
patch is for 7.0-CURRENT code, but should work with 6.2 too.

Don't forget to copy /sys/sys/shm.h into /usr/include/sys/shm.h before
recompiling /usr/src/usr.bin/ipcs program. Other programs that are using
shmid_ds structure may need recompilation too.
