This will hopefully prevent confusion like that in bug 1215903.

The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
CLOSED TREE makes big refactorings like this a piece of cake.

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.
Similar to the last patch, we copy any sub-protocols a protocol owns
before destroying the sub-protocols. We do this to ensure a stable
iteration over the sub-protocols, as destroying a sub-protocol may
trigger other sub-protocol deletions. Let's permit an existing
interface method to do the copying for us, so if the details of how we
store sub-protocols change, this call site is insulated from the
details.
In $PROTOCOL::CloneManages, we reach directly into the other protocol's
sub-protocol arrays to copy them. It would be better, from a
fewer-places-to-modify-when-things-change point of view if we used the
$PROTOCOL::Managed$SUBPROTOCOL array getter that already exists for this
purpose. A good compiler should be able to remove the function call
overhead...but cloning managees is probably expensive anyway, so a
function call here doesn't matter much.
It's not immediately obvious to me why we clone and then iterate over
the clone, rather than iterating directly, but perhaps there are subtle
IPDL dragons lurking hereabouts.
The functions:
- _callCxxArrayInsertSorted
- _callCxxArrayRemoveSorted
- _callCxxArrayClear
- _cxxArrayHasElementSorted
are only ever used to touch the managed sub-protocol arrays of a
protocol. It would be better if they reflected the *intent* of what
they were doing, rather than what C++ function they were calling, since
we're about to change that.
Windows messages can trigger sync ipc messages to the child process. That
means if we handle windows messages while waiting for the response to a sync
a11y ipc message we can end up reentering the code to send ipc messages which
is bad. Try and avoid this situation by not handling windows messages while
waiting for a sync a11y message.
Like the last patch, the motivation is to remove a GetVersionEx() call which
triggers deprecation warnings.
Because Windows XP SP2 is the earliest Windows version we support, two of the
existing uses of GetWinVersion() could be removed, because they were checking
for XP or earlier. One other Vista check could be replaced with
mozilla::IsVistaOrLater().

The motivation here is to remove the GetVersionEx() calls in the
Windows-specific code, because that function is deprecated and causes warnings.
The non-Windows versions come along for the ride.

The warning is "the address of NuwaMarkCurrentThread() will always evaluate to
'true'".
