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.

Delete subrepo argparse/:argparse
Delete subrepo base32/:base32

Delete subrepo cfg-if/:cfg-if
Delete subrepo getrandom/:getrandom
Delete subrepo lazy-static/:lazy-static
Delete subrepo libc/:libc
Delete subrepo nitrokey-sys/:nitrokey-sys

-  informing the optimiser that indexing is never out-of-bounds.
-
-### Removed
-- Removed the Deprecated `choose_option`
-
-
-## [Rust 0.11.0] - 2014-07-02
-### Added
-- document when to use `OSRng` in cryptographic context, and explain why we use `/dev/urandom` instead of `/dev/random`
-- `Rng::gen_iter()` which will return an infinite stream of random values
-- `Rng::gen_ascii_chars()` which will return an infinite stream of random ascii characters
-
-### Changed
-- Now only depends on libcore!
-- Remove `Rng.choose()`, rename `Rng.choose_option()` to `.choose()`
-- Rename OSRng to OsRng
-- The WeightedChoice structure is no longer built with a `Vec<Weighted<T>>`,
-  but rather a `&mut [Weighted<T>]`. This means that the WeightedChoice
-  structure now has a lifetime associated with it.
-- The `sample` method on `Rng` has been moved to a top-level function in the
-  `rand` module due to its dependence on `Vec`.
-
-### Removed
-- `Rng::gen_vec()` was removed. Previous behavior can be regained with
-  `rng.gen_iter().take(n).collect()`
-- `Rng::gen_ascii_str()` was removed. Previous behavior can be regained with
-  `rng.gen_ascii_chars().take(n).collect()`
-- {IsaacRng, Isaac64Rng, XorShiftRng}::new() have all been removed. These all
-  relied on being able to use an OSRng for seeding, but this is no longer
-  available in librand (where these types are defined). To retain the same
-  functionality, these types now implement the `Rand` trait so they can be
-  generated with a random seed from another random number generator. This allows
-  the stdlib to use an OSRng to create seeded instances of these RNGs.
-- Rand implementations for `Box<T>` and `@T` were removed. These seemed to be
-  pretty rare in the codebase, and it allows for librand to not depend on
-  liballoc.  Additionally, other pointer types like Rc<T> and Arc<T> were not
-  supported.
-- Remove a slew of old deprecated functions
-
-
-## [Rust 0.10] - 2014-04-03
-### Changed
-- replace `Rng.shuffle's` functionality with `.shuffle_mut`
-- bubble up IO errors when creating an OSRng
-
-### Fixed
-- Use `fill()` instead of `read()`
-- Rewrite OsRng in Rust for windows
-
-## [0.10-pre] - 2014-03-02
-### Added
-- Seperate `rand` out of the standard library
