[dsf-gdb] Put back event assert in

Browse source 
MIMemoryTest.writeCharVarying{Address,Offset}

When we switched SyncUtil.readMemory to use queries, it exposed a race
condition with the asserts that check for the number of event received.
Basically, nothing guarantees that when the assert is evaluated the
event had the time to arrive.

We now use a ServiceEventWaitor to wait until the event arrives (with a
timeout, of course).

At the same time, rename word_size to wordSize.
