For a few cases where we handle secret information it's good to clear
the buffers containing sensitive data before freeing them.
Introduce VIR_DISPOSE, VIR_DISPOSE_N and VIR_DISPOSE_STRING that allow
simple clearing fo the buffers holding sensitive information on cleanup
paths.
In debugging a crash on OOM, I thought that the virInsert APIs
might be at fault, but couldn't isolate them as a cause. While
the viralloc APIs are used in many test suites, this is as a
side-effect, they are not directly tested :-)
