Added LFS_INFO, upgraded most LFS_DEBUG statements

Browse Source 
This adds LFS_INFO and limits LFS_DEBUG to opt-in debug output.

Note that while LFS_DEBUG seems to be only used in LFS_DEBUGRBYDBALANCE,
it can also be useful for adding additional logging while debugging.

Having separate levels here is useful for filtering. Users should be
able to expect LFS_INFO output to not bog down a system, while LFS_DEBUG
can be a free-for-all dumping ground of debug info.

This also converges to the common 4 levels of logging found in other
systems, which was an intentional non-goal, but it's interesting to see
how each level serves a purpose.
