Our accSelection implementation always returns an IUnknown which clients QI to IEnumVARIANT.
Marshaling as IUnknown works fine in this case, but it's more efficient and correct to marshal the correct interface.
Also, without this, we'd hit an assertion.

We only use the handler for specific interfaces such as IAccessible* and IAccessibleHyperlink.
For interfaces which don't use the handler, we currently write an empty payload, but this still adds bytes to the stream.
This seems to break marshaling such an interface in a VT_UNKNOWN in a VARIANT.
To fix this, just don't write any payload at all when we aren't using the handler for the target interface.

In order to support IA2 live regions with e10s (bug 1322532), text change events sent from the child process to the parent process use sync IPC.
That comes at a slight performance cost: the content process is blocked until the parent returns from sending and handling the event.
However, there is no reason to do this if the event is not for an accessible inside a live region; current clients don't need the sync behaviour outside of live regions.

On mingw this causes IIDs to be defined in headers. Those definitions conflict with _i.c files that are included as well. Since we include _i.c anyway, INITGUID is simply not needed.
widl can't handle generating the typelib without explicit importlib() in this case. This should be fixed in widl as well, but using importlib() in this case looks right anyway.

When determining if an author provided an empty alt attribute versus no alt attribute at all, our image accessible name is either an empty string or a null string. Screen readers can then choose to guess the name from the source if the author did not explicitly provide an empty alt text and thus marked the image as decorative.
The accessible handler for the Windows remote processes did not account for this distinction, always returning what appeared to be an empty string. This was found while determining why NVDA wasn't guessing the SRC from a non-labelled graphical link. NVDA checks to see if the name returned by the link accessible is null, and then decides to look for the graphical children if that is the case.

In order to send send attributes in BatchData we will need to convert
them to an array. Here we factor out the private function that does that
and put it in nsAccUtils.

All but one of the current uses of DEFFILE use `SRCDIR + '/file.def'` to
get a srcdir-relative path anyway, and the other one wants an
objdir-relative path, so using Path makes everything clearer.
This makes it more straightforward to translate the paths for the WSL
build.
If GetInitialInterceptorForIID fails, the live set lock is not released in most cases, but the newly created Interceptor will be destroyed.
The Interceptor's destructor tries to acquire the live set lock again, but that causes a deadlock, since reentry is no longer allowed for a mutex after bug 1364624.
GetInitialInterceptorForIID now ensures the live set lock is always released on failure, thus preventing the deadlock.
