jade 53e0b6ecfb tree-wide: fix a pile of lints
Mostly these are bugprone-unused-local-non-trivial-variable.

Also fix instances of:
- bugprone-optional-value-conversion
- bugprone-inc-dec-in-conditions (please check this loop is correct, it
  is the only non trivial code change in here)
- bugprone-unused-return-value (well, by fixing the lint config)

There are three notable changes relating to undefined vars:
- openLogFile ignoring the result. This is because openLogFile does a
  whole bunch of mutation of member variables
- hiliteMatches: i am guessing this is because showing the derivation
  name was unhelpful and it just got changed
- canonPath in NarAccessor: canonPath inside of a thing that is supposed
  to be vfs based cannot possibly be correct, so let's delete it given
  it is unused.

Fixes: #584
