librb: silence some fairly harmless compiler warnings
These include warnings about "break" statements that will never be
executed (because they are after "return" statements), unused macros
(lost to code refactoring or never even used in the first place),
functions that call abort() or loop indefinitely but aren't marked with
the "noreturn" attribute, and use of variables possibly uninitialised
(a false positive).

openssl: More LibreSSL compatibility
LibreSSL does not have the new version macros & functions that OpenSSL
1.1.0 implements. This causes a compile-time failure against LibreSSL.

Further, the runtime function for returning the library version returns
the wrong number (the hardcoded constant number SSLEAY_VERSION_NUMBER
aka OPENSSL_VERSION_NUMBER, instead of LIBRESSL_VERSION_NUMBER).

Add more ifdef soup to remedy the situation.

openssl: change how we load DH parameters
The code already assumes the presence of fopen(3) and errno, and, by
extension, fclose(3) and strerror(3), so just use those instead of the
BIO wrappers.

Additionally, don't fail to initialise if the DH file does exist but
parsing it fails, as per the pre-existing comment about them being
optional.

[mbedtls] Various fixes and improvements
* Move certificate, key, DH parameters and configuration to heap
  (Documentation states that setting new configuration, e.g.
   during a rehash, is unsupported while connections using that
   configuration are active)

  This is the same approach as the fix for #186

  Refcount these structures so as to not introduce a memory leak

  On rehash, it will use new structures only if there are no
  errors in constructing them

* Make fingerprint generation work for TLS connections

  See the comments in the newly created file for an explanation

* Fix memory leak when generating a fingerprint from a file

* Add better error-reporting (strings in addition to numbers)
  where possible

* Coalesce several connection memory allocations into one function

* Reduce boilerplate where possible (Charybdis targets C99)

* Support private key being in certificate file, and having no
  DH parameters file

* Correct erroneous closing comment

[openssl] More improvements to the backend
* Don't manually initialise libssl 1.1.0 -- it does this automatically
* SSL_library_init() should be called first otherwise
* Move SSL_CTX construction to rb_setup_ssl_server()
* Test for all required files (certificate & key) before doing anything
* Free the old CTX before constructing a new one (Fixes #186)
* Don't try to set options / ciphers etc on a NULL CTX
* Clean up ifdef indentation
* Fix DH parameters memory leak

Partially revert previous commit
The OpenSSL backend is the only one that assigns a non-constant
value to the length variable. Use the correct type for its
pointer and cast instead.

ssld: Add new certfp_methods spki_sha256 and spki_sha512
These operate on the SubjectPublicKeyInfo of the certificate, which does
change unless the private key is changed. This allows the fingerprint to
stay constant even if the certificate is reissued.

(The same fingerprint is also used by DANE)
