[boost] Additions to optional<>

Hello

I have a couple of pending additions to the Optional library.
These are _new_ functions, so they shouldn't disrupt the release.
Specifically:

from_optional(o,default_value)

and

make_optional(condition,value)

Given that the release is still ahead, is it OK to merge these additions to 
RC_1_34_0 or should I keep them in the trunk?

TIA
