Add error reporting to machine spec paser Currently machine specification (`/etc/nix/machine`) parser fails with a vague exception if the file had incorrect format. This commit adds verbose exceptions and unit-tests for the parser.

#include "machines.hh"
Split up `util.{hh,cc}` All OS and IO operations should be moved out, leaving only some misc portable pure functions. This is useful to avoid copious CPP when doing things like Windows and Emscripten ports. Newly exposed functions to break cycles: - `restoreSignals` - `updateWindowSize`

Restore exposing machine file parsing This was accidentally removed in e989c83b44d7c4d8ffe2e5f4231e4861c5f7732f. I restored it and also did a few other cleanups: - Make a static method for namespacing purposes - Put the test files in the data dir with the other test data - Avoid mutating globals in the machine config tests This will be used by Hydra.
