Drop support for Ruby 2.3, 2.4, and 2.5.
As of 2021-10, Ruby 2.6 is the oldest version that still receives
security fixes from the Ruby core team, so it doesn't make much sense
to keep code for those ancient versions.

On the server side, the serialized list of protocols is stored in
SSL_CTX as a String object reference. We utilize a hidden instance
variable to prevent it from being GC'ed, but this is not enough because
it can also be relocated by GC.compact.

We store the reverse reference to the Ruby object in the OpenSSL
struct for use from OpenSSL callback functions. To prevent the Ruby
object from being relocated by GC.compact, we must "pin" it by calling
rb_gc_mark().

Similarly to SSLSocket#syswrite, the blocking SSLSocket#sysread allows
context switches. We must prevent other threads from modifying the
string buffer.
We can use rb_str_locktmp() and rb_str_unlocktmp() to temporarily
prohibit modification of the string.

Provide a wrapper of SSL_set0_tmp_dh_pkey()/SSL_CTX_set_tmp_dh(), which
sets the DH parameters used for ephemeral DH key exchange.
SSLContext#tmp_dh_callback= already exists for this purpose, as a
wrapper around SSL_CTX_set_tmp_dh_callback(), but it is considered
obsolete and the OpenSSL API is deprecated for future removal. There is
no practical use case where an application needs to use different DH
parameters nowadays. This was originally introduced to support export
grade ciphers.
RDoc for #tmp_dh_callback= is updated to recommend the new #tmp_dh=.
Note that current versions of OpenSSL support automatic ECDHE curve
selection which is enabled by default. SSLContext#tmp_dh= should only be
necessary if you must allow ancient clients which don't support ECDHE.

This change fixes alias call-seq to return nil if the method's
call-seq does not specify the alias.
Previously, the alias's call-seq would be an empty string in this case
which broke darkfish rendering.
This change also backfills test coverage for 0ead786 which moved
call-seq deduplication into AnyMethod.

Previously, Parser::C comments all defaulted to "rdoc" format, even
when the user had set a different default with the `--markup=<choice>`
option.
