Think about patching our xcb-proto with x11rb-specific changes

[eduardosm]

There are some issues that could be fixed by modifying the XML definitions. For example #156 could be fixed by adding name= attributes and #357 could be fixed by fixing and uncommenting the broken definitions. Additionally, some unions could be converted into switches to make the API more rust-y.

However, many of those modifications cannot be merged upstream because they would likely break libxcb. So, it might be a good idea to think about a way of patching our copy of xcb-proto with x11rb-specific changes.

For now, I'd prefer to merge changes upstream. In theory, I have commits right there, but in practice, I never really touched xcb-proto and only did some things on libxcb. Thus, I would not really want to "just merge" something there.

Anyway, the name= you propose for #156 could just be added there. Uncommenting the broken definitions for #357 could be merged upstream together with an extra patch to libxcb that makes it ignore the new stuff in there.

I am not really sure about converting unions to switches. For xproto's ClientMessageData... oh, that's actually possible. Same for the <union> in randr. Hm, nice idea.
