Subject: 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.

-/// A macro for defining #[cfg] if-else statements.
-///
-/// This is similar to the `if/elif` C preprocessor macro by allowing definition
-/// of a cascade of `#[cfg]` cases, emitting the implementation which matches
-/// first.
-///
-/// This allows you to conveniently provide a long list #[cfg]'d blocks of code
-/// without having to rewrite each clause multiple times.

-// This is a pretty horrible hack to allow us to conditionally mark
-// some functions as 'const', without requiring users of this macro
-// to care about the "const-extern-fn" feature.
-//
-// When 'const-extern-fn' is enabled, we emit the captured 'const' keyword
-// in the expanded function.
-//
-// When 'const-extern-fn' is disabled, we always emit a plain 'pub unsafe extern fn'.
-// Note that the expression matched by the macro is exactly the same - this allows
-// users of this macro to work whether or not 'const-extern-fn' is enabled
-//
-// Unfortunately, we need to duplicate most of this macro between the 'cfg_if' blocks.
-// This is because 'const unsafe extern fn' won't even parse on older compilers,
-// so we need to avoid emitting it at all of 'const-extern-fn'.
-//
-// Specifically, moving the 'cfg_if' into the macro body will *not* work.
-// Doing so would cause the '#[cfg(feature = "const-extern-fn")]' to be emiited
-// into user code. The 'cfg' gate will not stop Rust from trying to parse the
-// 'pub const unsafe extern fn', so users would get a compiler error even when
-// the 'const-extern-fn' feature is disabled
-//
-// Note that users of this macro need to place 'const' in a weird position
-// (after the closing ')' for the arguments, but before the return type).
-// This was the only way I could satisfy the following two requirements:
-// 1. Avoid ambuguity errors from 'macro_rules!' (which happen when writing '$foo:ident fn'
-// 2. Allow users of this macro to mix 'pub fn foo' and 'pub const fn bar' within the same
-// 'f!' block
