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.

-//! Interface to the random number generator of the operating system.
-//!
-//! # Platform sources
-//!
-//! | OS | interface
-//! |------------------|---------------------------------------------------------
-//! | Linux, Android | [`getrandom`][1] system call if available, otherwise [`/dev/urandom`][2] after successfully polling `/dev/random`
-//! | Windows | [`RtlGenRandom`][3]
-//! | macOS | [`getentropy()`][19] if available, otherwise [`/dev/random`][20] (identical to `/dev/urandom`)
-//! | iOS | [`SecRandomCopyBytes`][4]
-//! | FreeBSD | [`getrandom()`][21] if available, otherwise [`kern.arandom`][5]
-//! | OpenBSD | [`getentropy`][6]
-//! | NetBSD | [`kern.arandom`][7]
-//! | Dragonfly BSD | [`/dev/random`][8]
-//! | Solaris, illumos | [`getrandom`][9] system call if available, otherwise [`/dev/random`][10]
-//! | Fuchsia OS | [`cprng_draw`][11]
-//! | Redox | [`rand:`][12]
-//! | CloudABI | [`cloudabi_sys_random_get`][13]
-//! | Haiku | `/dev/random` (identical to `/dev/urandom`)
-//! | L4RE, SGX, UEFI | [RDRAND][18]
-//! | Hermit | [RDRAND][18] as [`sys_rand`][22] is currently broken.
-//! | VxWorks | `randABytes` after checking entropy pool initialization with `randSecure`

-//!
-//! Getrandom doesn't have a blanket implementation for all Unix-like operating
-//! systems that reads from `/dev/urandom`. This ensures all supported operating
-//! systems are using the recommended interface and respect maximum buffer
-//! sizes.
-//!
-//! ## Unsupported targets
-//!
-//! By default, compiling `getrandom` for an unsupported target will result in
-//! a compilation error. If you want to build an application which uses `getrandom`
-//! for such target, you can either:
-//! - Use [`[replace]`][replace] or [`[patch]`][patch] section in your `Cargo.toml`
-//! to switch to a custom implementation with a support of your target.
-//! - Enable the `dummy` feature to have getrandom use an implementation that always
-//! fails at run-time on unsupported targets.
-//!
-//! [replace]: https://doc.rust-lang.org/cargo/reference/manifest.html#the-replace-section
-//! [patch]: https://doc.rust-lang.org/cargo/reference/manifest.html#the-patch-section
-//!
-//! ## Support for WebAssembly and asm.js
-//!
-//! Getrandom supports all of Rust's current `wasm32` targets, and it works with
-//! both Node.js and web browsers. The three Emscripten targets
-//! `asmjs-unknown-emscripten`, `wasm32-unknown-emscripten`, and
-//! `wasm32-experimental-emscripten` use Emscripten's `/dev/random` emulation.
-//! The WASI target `wasm32-wasi` uses the [`__wasi_random_get`][17] function
-//! defined by the WASI standard.
-//!
-//! Getrandom also supports `wasm32-unknown-unknown` by directly calling
-//! JavaScript methods. Rust currently has two ways to do this: [bindgen] and
-//! [stdweb]. Getrandom supports using either one by enabling the
-//! `wasm-bindgen` or `stdweb` crate features. Note that if both features are
-//! enabled, `wasm-bindgen` will be used. If neither feature is enabled, calls
-//! to `getrandom` will always fail at runtime.
-//!
-//! [bindgen]: https://github.com/rust-lang/rust-bindgen
-//! [stdweb]: https://github.com/koute/stdweb
-//!
-//! ## Early boot
-//!
-//! It is possible that early in the boot process the OS hasn't had enough time
-//! yet to collect entropy to securely seed its RNG, especially on virtual
-//! machines.
-//!
-//! Some operating systems always block the thread until the RNG is securely
-//! seeded. This can take anywhere from a few seconds to more than a minute.
-//! Others make a best effort to use a seed from before the shutdown and don't
-//! document much.
-//!
-//! A few, Linux, NetBSD and Solaris, offer a choice between blocking and
-//! getting an error; in these cases we always choose to block.
-//!
-//! On Linux (when the `getrandom` system call is not available) and on NetBSD
-//! reading from `/dev/urandom` never blocks, even when the OS hasn't collected
-//! enough entropy yet. To avoid returning low-entropy bytes, we first read from
-//! `/dev/random` and only switch to `/dev/urandom` once this has succeeded.
-//!
-//! # Error handling
-//!
-//! We always choose failure over returning insecure "random" bytes. In general,
-//! on supported platforms, failure is highly unlikely, though not impossible.
-//! If an error does occur, then it is likely that it will occur on every call to
-//! `getrandom`, hence after the first successful call one can be reasonably
-//! confident that no errors will occur.
-//!
-//! On unsupported platforms, `getrandom` always fails. See the [`Error`] type
-//! for more information on what data is returned on failure.
