prefix bitset with namespace to avoid ambiguity

due to "using namespace" statements, there is an ambiguity between std::bitset and persistent_data::bitset.  this patch fixes it for me.

> this patch fixes it for me.

btw, my patch was merged upstream.

[Comment 3 Michael Behrns-Miller 2013-12-14 03:31:19 UTC]

I'm having this same problem as I unmasked boost 1.55 for some development work.

If the patch is rolled into a masked portage version I will gladly test it.  Thanks!

InCVS.
