Currently, OpenSSL does not have the required
`EVP_PKEY_get1_ED(25519|448)` functions, hence EdDSA has been partially
implemented and disabled. Once OpenSSL 3.0.0 is out and the `openssl`
crates implements the bindings to those functions, full EdDSA
implementation could be done and activated.
Conditional compilation has been implemented using `rustc-cfg`
instructions rather than features so it can be activated from the build
script depending on whether or not the cryptographic library supports
Ed25519 and Ed448.

`reqwest` is a very good crate, however ACMEd does not require most of
its functionalities. For this job, `attohttpc` is also great and comes
with much less dependencies.
rel #1
The previous HTTP back-end was tightly coupled with the threads, which
was very inconvenient. It is now completely decoupled so a new threading
model may be implemented.
This project provides binaries without any link to Rust or Cargo. It is
just normal binaries that appears to be written in Rust. Therefore, it
does not makes any sense to distribute them in a Rust-specific registry.
Furthermore, such publication would not include the man pages
installation may not respect some distribution-specific policies.
As discussed in #2, ring is not mature enough to replace OpenSSL. Hence,
the standalone mode which has been made to implement such a replacement
has to be removed until ring becomes usable.
