2035f8a324 lib.fileset.fileFilter: Don't run predicate unnecessarily 
Before:

    nix-repl> fileset.trace (fileset.fileFilter (file: builtins.trace file.name false) ./default.nix)
    trace: README.md
    trace: benchmark.sh
    trace: default.nix
    trace: internal.nix
    trace: mock-splitRoot.nix
    trace: tests.sh

After:

    nix-repl> fileset.trace (fileset.fileFilter (file: builtins.trace file.name false) ./default.nix)
    trace: default.nix

0ace383438 lib.fileset: Make error messages more uniform 
Just minor changes like:
- Always using "X is a Y, but it should be Z"
- "X is a path that does not exist" rather than "X does not exist"
- Always using multi-line strings for errors
- Always quoting string-like values and not quoting path-like values
  - But do quote filesystem roots. Even though they're paths, they might
    be very small, good to have quotes to know the start/end
- Capitalise the first word
- Distinguish root vs filesystem root more

Compared to the parent commit, this removes any detectable performance
cost :)

This does decrease performance unfortunately

4f35f003e6 lib.fileset: Internal representation v3, empty value without a base 
`unions []` now works!

Notably the new empty value without a base is not exposed in the interface.
I don't know of any use case for it.
