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.
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.
* 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
* 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
* Properly allow no DH parameters (some backends come with defaults)
* If no private key is given, assume it's in the certificate file
* Use correct length calculation in buffer for TLS options
* Fix compiler warnings regarding uint64_t stats counters
openssl:
* 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)
* Properly abort rb_setup_ssl_server() on CTX construction failures
* Support ECDHE on more than one curve on OpenSSL 1.0.2 and above
* Clean up ifdef indentation
* Fix DH parameters memory leak
mbedtls:
* Fix certificate fingerprint generation
* Fix library linking order
* Fix incorrect printf()-esque argument count
* Return digest length for fingerprints instead of 1, consistent
with the other backends
sslproc / ssld:
* Fingerprint methods have no assocated file descriptors
* Send TLS information (cipher, fingerprint) before data
* Use correct header length for fingerprint method

If change_connid is called with an unknown ID, conn will be
NULL, check this with an assert and then respond by reporting
the new ID as closed instead of dereferencing a NULL pointer.
extb_usermode and extb_hostmask both use the same extban character
('m'), resulting in only one of the modules being usable (depending
on module load order) and neither one functioning if one of them
is unloaded.
This changes the character for extb_usermode from 'm' to 'u'.

RPL_ADMINME is a response the client receives using the ADMIN command.
Charybdis used to implement a non-standard version of this.
The RFC 1459 standard [1] says in section "6.2 Command responses.":
256 RPL_ADMINME
"<server> :Administrative info"
This commit corrects the behavior to follow the standard.
