Bug 1428930 - Move some XBL accessibility roles into XULMap.h.

Details 
As of Bug 1403231 we have a way to declare roles on a tag name as an alternative to doing it on a XBL binding: https://dxr.mozilla.org/mozilla-central/source/accessible/base/XULMap.h.

So far we've moved these one-by-one as we tackle the individual bindings, but if we front-load that work we can continue to use artifact builds for the individual binding removals (which often don't require other platform changes).

See the ~40 bindings using the [role] feature here: https://bgrins.github.io/xbl-analysis/tree/#role. 

There may be cases where the binding can't be keyed off a tag name only (since XBL bindings can be attached to any arbitrary CSS selector).  In that case, we could either not include them in this bug or add necessary XULMap features to handle these cases (like allowing attribute selectors in the mapping). I'd prefer to do the former for this bug to keep things simple, and we can handle the tougher cases in a follow up.
It may be the case that we can only easily do this with 'leaf' bindings that don't have any children that extend them.  For example "button-base" has a role of "xul:button" but nothing ever directly creates button-base, the role is surely carried through to extended bindings that don't define their own role:

button-base [role="xul:button"]
  button
    button-repeat
  ctrlTab-preview
  menu-button-base
    download-subview-toolbarbutton
    menu-button

To move the role off of button I think we'd need to capture every tag of all children (which may or may not be difficult depending on the case). That said, there are plenty of cases where it'll be easier.
I'm looking into this.

I'm building a list of bindings and associated CSS selectors to find out which groups always apply to the same tag.

Since there is a limited number of bindings to go through, I'm doing this manually with DXR searches and I'm cross-checking the results with the list in <https://bgrins.github.io/xbl-analysis/tree/#role>. In doing this, I've noticed that the latter doesn't report bindings with the same name in different files, for example only one of these bindings is shown:

https://dxr.mozilla.org/mozilla-central/search?q=%23menu%22
Flags: needinfo?(bgrinstead)
I found at least one case where a custom binding that should probably inherit from a base one doesn't:

https://dxr.mozilla.org/mozilla-central/rev/c38d22170d6f27e94c3c53093215d20255fab27a/browser/components/preferences/handlers.css#13-15

My guess is that in this case the richlistitem doesn't get a role assigned, although it should. Assigning a role to all richlistitem tags would fix this. While we should in theory search the CSS selectors for all bindings and see if there are more cases like this, I don't think that it matters in practice, as we would be most likely fixing existing bugs by assigning a role where there wasn't one.
Here are the bindings with an explicit XUL role attached, listed together with the ones that inherit from them without overriding the role. Each entry includes the CSS selectors used to apply the binding, which in some cases are also platform-specific or inside media queries.

I've excluded the "browser", "editor", and "iframe" bindings that have role="outerdoc". Another special case is "menu-vertical", which is unused in mozilla-central but still referenced in comm-central.

Thanks, this was an issue with some other bindings and I just had missed this menu case. Right now I fix this by prefixing all bindings in certain files with another string (https://github.com/bgrins/xbl-analysis/blob/0b2b868c1ac84a40eab4fe89720bd8e3067bead2/scripts/xbl-files.js#L201-L217). For this case I should probably change the id of just the 'menu' binding in those files.
Flags: needinfo?(bgrinstead)
I made a list of the simpler cases that can be handled just by adding tags to XULMap, but I won't be able to use full builds for the next two weeks, so feel free to take the bug in the meantime. It would also be nice to fix bug 1414230 before adding all the constructor functions to the separate file, but not required.

The richlistitem tag is a special case that I think is simple enough to be handled in this bug. We should add back role="xul:listitem" to the "toolkit/mozapps/update/content/updates.xml#update" binding, since it's bound to a custom "update" tag instead of a richlistitem. Alternatively we can change the code to use a class instead of a custom tag, although the latter may need more testing.

Here are the bindings whose role I'm confident can be removed and added back to tags:

Is this bug simply involved looking at comment 7 and add them into XULMap.h and nsAccessibilityService.cpp like what :bgrins did in bug 1422386?  

https://hg.mozilla.org/try/rev/8b6f96efe45b915f28bc6c89c29b60bad598abc0#l1.9

If so I can provide a drive-by fix so we could unblock a few more things, and for you to work on other things in parallel.
Flags: needinfo?(paolo.mozmail)
(Not exactly drive-by, it would still take some time to test the patch out and stuff, so don't worry about it if you already have an WIP ready)
Yes, this bug is simple to implement but I was already working on it. I fixed bug 1414230 first to make it easier to create the table, then I addressed all the bindings in comment 7 minus the "popup" and "menupopup" tags because I found out there's an explicit lookup for their XBL role in XULButtonAccessible::IsAcceptableChild.

You can look at bug 1430777 if you want to convert this or some of the other more complex cases. The conversions don't need to happen all at the same time, you can file new bugs and tackle them a few at a time.
Flags: needinfo?(paolo.mozmail)
To make the process simpler, I didn't actually remove any binding even when they were only setting the role. There are already bugs on file for these cases, like bug 1422386.

nit: it probably meant 'or' not 'of'

there's bunch of bindings in comm-central (outside mozilla folder), which will should be checked before landing the patch. Paolo, is it something you could take care of?

Flags: needinfo?(paolo.mozmail)
At present I've only noticed that the "panebutton" binding in "common/bindings/preferences.xml" may be affected by this patch. We didn't have to take care of this binding because we have already removed support for preferences windows entirely.

A simple workaround can be to change the code so the panebutton is bound to a tag that already gets the "xul:listitem" role thanks to the new tag mapping, instead of a custom tag.

I'll file a bug with this information.
