The SSL_library_init() function has been removed. (There's a new
SSL_init_ssl() function, but calling it is optional.) The
SSL_load_error_strings() function is similarly gone.
The SSLv23_client_method() and SSLv23_server_method() functions
are also gone. The new TLS_client_method() and TLS_server_method()
functions are better names for what SSLv23_client_method() and
SSLv23_server_method() evolved to do.
Finally, the dance for server-triggered renogotiation needs to
change, since the old dance involved manipulating the structure
directly.

When creating a collision node, make sure the "has a value" bit
is set, since the "has a hash code" bit should imply it.
This bug was made easier to trigger by 3fbb384604, but it was
potentially a problem for scope sets before.
Closes#1366
Merge to v6.6
This function exposes the fast subset operation that is built in for
immutable hash tables (and used by the set-of-scopes implementation).
Also, make the space optimization implicit for `eq?`-based hash tables
that contain only #t values (instead of explicit and only available
internally). It turns out to be easy and efficient to make the
representation automatic, because the HAMT implementation can support
a mixture of nodes with some containing explicit values and some
containing implicit #t values.
Now with-disappeared-uses surrounds its body with let, so it can contain
multiple body expressions. The record-disappeared-use function is like
record-disappeared-uses but for a single identifier.
The `#%linklet` module is intended to eventually provide
a simplified compiler for the core Racket language. For
now, it provides minimal hooks for bootstrapping an
expander implementation.
When the properties argument for `make-struct-type` is non-empty,
then we cant; guarantee that `make-struct-type` succeeds, but
if it does, then we can still know that the result is a structure
type and (as long as `prop:chaperone-unsafe-undefined` is not
involved) the properties don't affect the constructor, predicate,
selector, or mutators.
The `eq?` hash code of a symbol, unreadable symbol, or keyword depends
only on the character content, but all in exactly the same way, so
that the same string would produce the same hash code for all. That's
not a big deal for hashing, but it doesn't seem like a good idea, and
it can be confusing.
