Obsolete Interprocess Communication Parameters

The Interprocess Communication (IPC) Message facility has been made more scalable in the Solaris 8 release by using kmem_alloc(9F) rather than rmalloc(9F) to allocate message text.

Therefore, the previously-documented msginfo_msgssz, msginfo_msgmap, and msginfo_msgseg tunables, which were artifacts of the rmalloc-based implementation, are obsolete in this release.
