Hi, Dirk.

What about the *MustCreate, *MustWait, and *MustLock functions?

  epicsEventMustCreate
  epicsEventMustWait
  epicsMutexMustCreate
  epicsMutexMustLock
  epicsThreadMustCreate

On a related note, I didn't look at all of them, but some of
these (e.g. epicsEventMustWait) are implemented as macros that
just do an assert on the return status of the regular non-must
function.  Others (e.g. POSIX epicsEventMustCreate) are actual
functions, but they too just do an assert.  If assertions are
disabled, this will do nothing and hence seems broken to me.  No?
