This doesn't particularly matter but is more consistent with DTLS and
avoids the callback being potentially called from two places.

The only difference is whether there's an alert to send back, but we'll
need to allow an "error without alert" in several cases anyway:
1. If the server sees an HTTP request or garbage instead of a
ClientHello, it shouldn't send an alert.
2. Resurfaced errors.
Just make zero signal no alert for now. Later on, I'm thinking we might
just want to put the alert into the outgoing buffer and make it further
uniform.
This also gives us only one error state to keep track of rather than
two.

This is analogous to the Go stack's handshakeErr field. Since it's quite
common for callers to run two I/O operations in parallel[*] like
SSL_read and SSL_write (or SSL_read and SSL_do_handshake for client
0-RTT). Accordingly, the new handshake state machine jams itself up on
handshake error, but to fully work with such callers, we should also
replay the error state.
This doesn't yet catch all cases (there are some parts of the read flow
which need to be fixed). Those will be resolved in later changes.
[*] Not actually in parallel, of course, but logically in parallel on a
non-blocking socket.

Apple messed up their headers and, if _POSIX_C_SOURCE is defined but
_DARWIN_C_SOURCE isn't, pthread.h no longer defines mach_port_t. They
then shipped a version of libc++ headers that is missing this fix, so
the build breaks:

If one uses XCode, they've hacked their pthread.h to provide mach_port_t

missing this.

that need _POSIX_C_SOURCE, but it appears none of these files actually

Although we are derived from 1.0.2, we mimic 1.1.0 in some ways around
our FOO_up_ref functions and opaque libssl types. This causes some
difficulties when porting third-party code as any OPENSSL_VERSION_NUMBER
checks for 1.1.0 APIs we have will be wrong.
Moreover, adding accessors without changing OPENSSL_VERSION_NUMBER can
break external projects. It is common to implement a compatibility
version of an accessor under #ifdef as a static function. This then
conflicts with our headers if we, unlike OpenSSL 1.0.2, have this
function.
This change switches OPENSSL_VERSION_NUMBER to 1.1.0 and atomically adds
enough accessors for software with 1.1.0 support already. The hope is
this will unblock hiding SSL_CTX and SSL_SESSION, which will be
especially useful with C++-ficiation. The cost is we will hit some
growing pains as more 1.1.0 consumers enter the ecosystem and we
converge on the right set of APIs to import from upstream.
It does not remove any 1.0.2 APIs, so we will not require that all
projects support 1.1.0. The exception is APIs which changed in 1.1.0 but
did not change the function signature. Those are breaking changes.
Specifically:
- SSL_CTX_sess_set_get_cb is now const-correct.
- X509_get0_signature is now const-correct.
For C++ consumers only, this change temporarily includes an overload
hack for SSL_CTX_sess_set_get_cb that keeps the old callback working.
This is a workaround for Node not yet supporting OpenSSL 1.1.0.
The version number is set at (the as yet unreleased) 1.1.0g to denote
that this change includes https://github.com/openssl/openssl/pull/4384.
