obsstore: disable garbage collection during initialization (issue4456)

Python garbage collection is triggered by container creation. So code that
creates a lot of tuples tends to trigger GC a lot. We disable the gc during
obsolescence marker parsing and associated initialization. This provides an
interesting speedup (25%).

Load marker function on my 58758 markers repo:
before: 0.468247 seconds
after:  0.344362 seconds

The benefit is a bit less visible overall. With python2.6 on my system I see:
after:  0.60
before: 0.53

The difference is probably explained by the delaying of a costly GC. (but there
is still a win). Marking involved tuples, lists and dicts as ignorable by the
garbage collector should give us more benefit. But this is another adventure.

Thanks goes to Siddharth Agarwal for the lead.
