bindings cleanup: move it, split it, import side effects, etc

[Antoine Martin]

• we now import it from the xposix platform code and that has side effects (registers its own event loop filter)
• it is getting too big (almost 2000 lines)
• 2 methods live in lowlevel/__init__.py but the rest lives in bindings..

time to do something about it

[Antoine Martin]

split some xkb stuff used in xpra/xposix

[Antoine Martin]

The patch above duplicates the xkb stuff so we can import xposix/gui without needing anything from wimpiggy/lowlevel, unfortunately:

• xclipboard, xsettings and xroot_props still import other bits
• it duplicates code rather than split it into a library portion

So, not going to be merged as is...

patch for the build files

[Antoine Martin]

r470 allows us to avoid the x11 event loop pollution from the client code.

It would still be preferable to split the bindings.so library so as to minimize the amount of code we load into the client process (800KB is quite a lot) so not closing this ticket yet.

[Antoine Martin]

Not a big priority since the major problem (x11 event loop pollution) is solved.

[Antoine Martin]

Mostly done in 0.10 by splitting the large gtk/X11 bindings into pure-X11 bindings and gtk bindings (see r3248 and many fixes after that).
This makes it a lot easier to switch away from gtk - even for the server components, should we want to do that.

This will do for now.

(setting correct milestone the work was completed in)
