Combine AbstractPos, PosAdapter, and Pos 
Also move `SourcePath` into `libutil`.

These changes allow `error.hh` and `error.cc` to access source path and
position information, which we can use to produce better error messages
(for example, we could consider omitting filenames when two or more
consecutive stack frames originate from the same file).

John Ericson f4ab297b31 Ensure all headers have #pragma once and are in API docs 
`///@file` makes them show up in the internal API dos. A tiny few were
missing `#pragma once`.

Robert Hensing f10465774f Force all Pos* to be non-null 
This fixes a class of crashes and introduces ptr<T> to make the
code robust against this failure mode going forward.

Thanks regnat for the idea of a ref<T> without overhead!

Eelco Dolstra e0204f8d46 Move path info caching from BinaryCacheStore to Store 
Caching path info is generally useful. For instance, it speeds up "nix
path-info -rS /run/current-system" (i.e. showing the closure sizes of
all paths in the closure of the current system) from 5.6s to 0.15s.

This also eliminates some APIs like Store::queryDeriver() and
Store::queryReferences().
