A lot of existing code has variations on:
if (ManagedPFooChild().Length()) {
...(ManagedPFooChild()[0])...
}
// Do something with nullptr, or some other action.
It's pretty reasonable to repeat this code when the managed protocols
are stored in an array; the code gets much less nice when managed
protocols are stored in a hashtable. Let's write a small utility
function to handle those details for us. Then when we change the
underlying storage, we only need to update this function, rather than a
bunch of callsites.
ProtocolUtils.h is included by all the generated IPDL headers, so
LoneManagedOrNull should be available everywhere the above pattern would
be encountered.
