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.

-lazy-static.rs
-==============
-
-A macro for declaring lazily evaluated statics in Rust.
-
-Using this macro, it is possible to have `static`s that require code to be
-executed at runtime in order to be initialized.
-This includes anything requiring heap allocations, like vectors or hash maps,
-as well as anything that requires non-const function calls to be computed.

-
-## Minimum supported `rustc`
-
-`1.27.2+`
-
-This version is explicitly tested in CI and may only be bumped in new minor versions. Any changes to the supported minimum version will be called out in the release notes.
-
-
-# Getting Started
-
-[lazy-static.rs is available on crates.io](https://crates.io/crates/lazy_static).
-It is recommended to look there for the newest released version, as well as links to the newest builds of the docs.
-
-At the point of the last update of this README, the latest published version could be used like this:
-
-Add the following dependency to your Cargo manifest...
-
-```toml
-[dependencies]
-lazy_static = "1.4.0"
-```
-
-...and see the [docs](https://docs.rs/lazy_static) for how to use it.
-
-# Example
-
-```rust
-#[macro_use]
-extern crate lazy_static;
-
-use std::collections::HashMap;
-
-lazy_static! {
-    static ref HASHMAP: HashMap<u32, &'static str> = {
-        let mut m = HashMap::new();
-        m.insert(0, "foo");
-        m.insert(1, "bar");
-        m.insert(2, "baz");
-        m
-    };
-}
-
-fn main() {
-    // First access to `HASHMAP` initializes it
-    println!("The entry for `0` is \"{}\".", HASHMAP.get(&0).unwrap());
-
-    // Any further access to `HASHMAP` just returns the computed value
-    println!("The entry for `1` is \"{}\".", HASHMAP.get(&1).unwrap());
-}
-```

-This directory contains snippets of code that should yield a
-warning/note/help/error at compilation. Syntax of annotations is described in
-[rust documentation](https://github.com/rust-lang/rust/blob/master/src/test/COMPILER_TESTS.md).
-For more information check out [`compiletest` crate](https://github.com/laumann/compiletest-rs).
-
-To run compile tests issue `cargo +nightly --test`.
-
-## Notes on working with `compiletest` crate
-
-* Currently code that is inside macro should not be annotated, as `compiletest`
-    crate cannot deal with the fact that macro invocations effectively changes
-    line numbering. To prevent this add a `// error-pattern:<your error message here>`
-    on the top of the file and make sure that you set `deny` lint level
-    if you want to test compiler message different than error.
-* `compiletest` crate by default sets `allow(dead_code)` lint level so make sure
-    that you change it to something suiting your needs even if the warning is
-    issued prior to any macro invocation.
-* If you get a message `error: 0 unexpected errors found, 1 expected errors not found`
-  despite the fact that some error was bound to occur don't worry - it's a known
-  issue in the `compiletest` crate and your error was probably not registered -
-  make sure that your annotations are correct and that you are setting correct
-  lint levels.

-/*!
-A macro for declaring lazily evaluated statics.
-
-Using this macro, it is possible to have `static`s that require code to be
-executed at runtime in order to be initialized.
-This includes anything requiring heap allocations, like vectors or hash maps,
-as well as anything that requires function calls to be computed.
-
-# Syntax
-
-```ignore
-lazy_static! {
-    [pub] static ref NAME_1: TYPE_1 = EXPR_1;
-    [pub] static ref NAME_2: TYPE_2 = EXPR_2;
-    ...
-    [pub] static ref NAME_N: TYPE_N = EXPR_N;
-}
-```
-
-Attributes (including doc comments) are supported as well:
-
-```rust
-# #[macro_use]
-# extern crate lazy_static;
-# fn main() {
-lazy_static! {
-    /// This is an example for using doc comment attributes
-    static ref EXAMPLE: u8 = 42;
-}
-# }
-```
-
-# Semantics
-
-For a given `static ref NAME: TYPE = EXPR;`, the macro generates a unique type that
-implements `Deref<TYPE>` and stores it in a static with name `NAME`. (Attributes end up
-attaching to this type.)
-
-On first deref, `EXPR` gets evaluated and stored internally, such that all further derefs
-can return a reference to the same object. Note that this can lead to deadlocks
-if you have multiple lazy statics that depend on each other in their initialization.
-
-Apart from the lazy initialization, the resulting "static ref" variables
-have generally the same properties as regular "static" variables:
-
-- Any type in them needs to fulfill the `Sync` trait.
-- If the type has a destructor, then it will not run when the process exits.
-
-# Example
-
-Using the macro:
-
-```rust
-#[macro_use]
-extern crate lazy_static;
-
-use std::collections::HashMap;
-
-lazy_static! {
-    static ref HASHMAP: HashMap<u32, &'static str> = {
-        let mut m = HashMap::new();
-        m.insert(0, "foo");
-        m.insert(1, "bar");
-        m.insert(2, "baz");
-        m
-    };
-    static ref COUNT: usize = HASHMAP.len();
-    static ref NUMBER: u32 = times_two(21);
-}
-
-fn times_two(n: u32) -> u32 { n * 2 }
-
-fn main() {
-    println!("The map has {} entries.", *COUNT);
-    println!("The entry for `0` is \"{}\".", HASHMAP.get(&0).unwrap());
-    println!("A expensive calculation on a static results in: {}.", *NUMBER);
-}
-```
-
-# Implementation details
-
-The `Deref` implementation uses a hidden static variable that is guarded by an atomic check on each access.
-
-# Cargo features
-
-This crate provides one cargo feature:
-
-- `spin_no_std`: This allows using this crate in a no-std environment, by depending on the standalone `spin` crate.
