Remove vendored dependencies

While it appears that by now we actually can get successful builds
without Cargo insisting on Internet access by virtue of using the
--frozen flag, maintaining vendored dependencies is somewhat of a pain
point. This state will also get worse with upcoming changes that replace
argparse in favor of structopt and pull in a slew of new dependencies by
doing so. Then there is also the repository structure aspect, which is
non-standard due to the way we vendor dependencies and a potential
source of confusion.
In order to fix these problems, this change removes all the vendored
dependencies we have.

-# cfg-if
-
-[Documentation](https://docs.rs/cfg-if)
-
-A macro to ergonomically define an item depending on a large number of #[cfg]
-parameters. Structured like an if-else chain, the first matching branch is the
-item that gets emitted.
-
-```toml
-[dependencies]
-cfg-if = "0.1"
-```
-
-## Example
-
-```rust
-cfg_if::cfg_if! {
-    if #[cfg(unix)] {
-        fn foo() { /* unix specific functionality */ }
-    } else if #[cfg(target_pointer_width = "32")] {
-        fn foo() { /* non-unix, 32-bit functionality */ }
-    } else {
-        fn foo() { /* fallback implementation */ }
-    }
-}
-
-fn main() {
-    foo();
-}
-```
