* Issue #1622 port `du` to windows
* Attempt to support Rust 1.32
Old version was getting "attributes are not yet allowed on `if`
expressions" on Rust 1.32
* Less #[cfg]
* Less duplicate code.
I need the return and the semicolon after if otherwise the second #[cfg]
leads to unexpected token complilation error
* More accurate size on disk calculations for windows
* Expect the same output on windows as with WSL
* Better matches output from du on WSL
* In the absence of feedback I'm disabling these tests on Windows.
They require `ln`. Windows does not ship with this utility.
* Use the coreutils version of `ln` to test `du`
`fn ccmd` is courtesy of @Artoria2e5
* Look up inodes (file ids) on Windows
* One more #[cfg(windows)] to prevent unreachable statement warning on linux
* Implemented --indicator-style flag on ls.
* Rust fmt
* Grouped indicator_style args.
* Added tests for sockets and pipes.
Needed to modify util.rs to add support for pipes (aka FIFOs).
* Updated util.rs to remove FIFO operations on Windows
* Fixed slight error in specifying (not(windows))
* Fixed style violations and added indicator_style test for non-unix systems
- convert to newer `?` syntax, fixing compiler warnings
+ requires MinSRV >= v1.13.0
.# [why]
The `?` operator was stabilized in rust v1.13.0.
Warnings requesting conversion from the old `try!` macro to the `?` operator
were introduced in rust v1.39.0.

Updates to individual integration tests
- use proposed conventional approach to beginning tests
- use new convenience functions for using fixtures
- use new names for TestScenario
Updates to integration test modules
- add proposed conventional module-level functions
Updates to test/common/util.rs
- rename TestSet, and its methods, for semantic clarity
- create convenience functions for use of fixtures
- delete convenience functions obsoleted by new conventions
