We've spread around FETCH_FAILED errors in quite a few places, and
that gives somewhat crude error records, as there's no way to tell if
the error was unavailable algorithms or some other error at such high
levels.
As an alternative, we take recording of these kinds of errors down to
the fetching functions, which are in a much better place to tell what
kind of error it was, thereby relieving the higher level calls from
having to guess.

Fixes#13183
From the original issue report, before this commit, on master and on
1.1.1, the issue can be detected with the following steps:
- Start with a default SSL_CTX, initiate a TLS 1.3 connection with SNI,
"Accept" count of default context gets incremented
- After servername lookup, "Accept" count of default context gets
decremented and that of SNI context is incremented
- Server sends a "Hello Retry Request"
- Client sends the second "Client Hello", now again "Accept" count of
default context is decremented. Hence giving a negative value.
This commit fixes it by adding a check on `s->hello_retry_request` in
addition to `SSL_IS_FIRST_HANDSHAKE(s)`, to ensure the counter is moved
only on the first ClientHello.

The openssl code base has only a few occurrences of 'unsigned const char'
(15 occurrences), compared to the more common 'const unsigned char' (4420
occurrences).
While the former is not illegal C, mixing the 'const' keyword (a 'type
qualifier') in between 'unsigned' and 'char' (both 'type specifiers') is a
bit odd.
The background for writing this patch is not to be pedantic, but because
the 'opmock' program (used to mock headers for unit tests) does not accept
the 'unsigned const char' construct. While this definitely is a bug in
opmock or one of its dependencies, openssl is the only piece of software we
are using in combination with opmock that has this construct.

FreeBSD's /dev/crypto does not provide a CIOCGSESSINFO ioctl, but it
does provide other ioctls that can be used to provide similar
functionality.
First, FreeBSD's /dev/crypto defines a CIOCGESSION2 ioctl which accepts
a 'struct session2_op'. This structure extends 'struct session_op'
with a 'crid' member which can be used to either request an individual
driver by id, or a class of drivers via flags.
To determine if the available drivers for a given algorithm are
accelerated or not, use CIOCGESSION2 to first attempt to create an
accelerated (hardware) session. If that fails, fall back to
attempting a software session. In addition, when requesting a new
cipher session, use the current setting of the 'use_softdrivers' flag
to determine the value assigned to 'crid' when invoking CIOCGSESSION2.
Finally, use the returned 'crid' value from CIOCGSESSION2 to look up
the name of the associated driver via the CIOCFINDDEV ioctl.

their Ex variants which have a new dwFlags parameter.
This flag allows the fiber to do floating-point arithmetic in the
fiber on x86, which would silently cause corruption otherwise since
the floating-point state is not switched by default.
Switch to these "new" APIs which were added in Vista.
