wollman a6e3c2a3ce Create a new branch of the kernel MIB, kern.ipc, to store
all of the configurables and instrumentation related to
inter-process communication mechanisms.  Some variables,
like mbuf statistics, are instrumented here for the first
time.

For mbuf statistics: also keep track of m_copym() and
m_pullup() failures, and provide for the user's inspection
the compiled-in values of MSIZE, MHLEN, MCLBYTES, and MINCLSIZE.
