Planning for Quantal: Boost

[Scott Kitterman]

The current upstream Boost release is 1.49.  This is also the default in 
Debian.  We should transition to that as the default for Quantal when archive 
is set up (before general uploading starts).

boost-defaults will need to be synced and boost1.49 will have to be uploaded 
and split, and put in Main.  We'll also need to create a boost-mpi-source1.49 
for the MPI related bits that can't go in Main.

As long as there's agreement that this is the right thing to do (I don't know 
what else we'd do) I can take care of this.  It does need to be in place 
before the first autosync run.
