[PATCH] Convert Tracker's BPoseView and related classes over to the layout API.

[waddlesplash]

This is a significant change. I initially planned to do this starting with Aldeck's branch, but that turned out to not be possible due to merge conflicts from PM and John's work.

The only known incompatibility this creates with BeOS is that Be told people in the Be Book (​here) that they could modify BFilePanel by probing around for the views and moving them around. The only application I found (so far) that does this ​is Pe. However, if there are any closed-source ones, we might have to come up with a workaround...

This fixes #4996, #3039, #3889, and possibly #8771 (Diver: can you double check me on all of these?).

The code is currently ​here (just one commit, as all this is inter-related) and a prebuilt "libtracker.so" for GCC2(Hybrid) is ​here (put it in non-packaged and blacklist the system's libtracker).

Other TODO:

• I need to clean up the inset construction on the layouts
• I need to do a go-over of the code to make sure I didn't screw anything obvious up
• Diver needs to test (and whoever else wants to)
• Axel needs to review the code (preferably someone else would too)

It seems that Gist does not like hosting binary files. You can find the current libtracker.so ​here.

Having Workspaces as replicant breaks Desktop redraw. AFAICT #3039 and #3889 are fixed by this patch.

There are a lot of apps customizing BFilePanel, the most common use is adding a "select folder" button. Several in-tree apps are doing this. You need to keep this working, and I'm afraid this means BFilePanel must stay without a layout, for now.

The big patch makes things uneasy to review. As everything is intermixed, you don't need to have each commit result in a compiling and running system, however, I think you can still split the work in smaller chunks for easier review.

OK, I'll try to figure out how to get that to work with the other changes I made to layouts...

I already talked to Axel, and he agreed that it should be in one large commit as it's all interdependent. There's no way to break changes out really, as some changes to the OpenWithWindow require other changes to PoseView, etc...

Please also check ​ImageFilePanel in Backgrounds, which provides an image preview.

Some actual examples of customized file panels:

• Wonderbrush "export as" has a way to pick a file format and open translator settings,

* Expander has a "select current directory" button.

[waddlesplash]

OK, will test against all of those.

I meant one commit to Haiku master (ie. a single hrev). I would prefer smaller chunked commits, too, otherwise.

[waddlesplash]

OK, I'll split it up at the end, it's easier to do it that way. Also, I opened a pull request for easier review ​here.

[waddlesplash]

Done, fixed all of Axel's comments as well as the FilePanel and got Workspaces working as well. It needs a final go-over and then a merge now.
