py: Wrap call with fb_alloc.

[kwagyeman]

This wraps fb_alloc around all functions/methods being called... so, it's not necessary to protect context anywhere else.

That said, it probably doesn't make sense to do this. fb_alloc_mark does a bunch of stuff and would slow down function calls. It's sensible probably just to keep wrapping image processing functions manually.

Anyway, just made the PR to show the code. Probably should close it.

You're right maybe we can optimize those functions to lower the overhead ?

Note this PR will not be merged either way, if we do add this feature it's not going to be added like this, I started by asking if we can add hooks, if we can, then I will push it upstream, cherry-pick it back here, and those hooks will be set in Makefiles.
