The write path for TLS is going to need some work. There are some fiddly
cases when there is a write in progress. Start adding tests to cover
this logic.
Later I'm hoping we can extend this flag so it drains the unfinished
write and thus test the interaction of read/write paths in 0-RTT. (We
may discover 1-RTT keys while we're in the middle of writing data.)

all existing test vectors are smaller than that.

Chaining doesn't make much sense. This means we have a discontinuity
when buffer BIOs are empty. For a general filter BIO, this isn't even
meaningful. E.g., the base64 BIO's next_bio doesn't use the same units
(There's one consumer which does call BIO_pending on a base64 BIO, hits
this case, and is only working on accident, I've left it alone for this
CL until we can fix that consumer.)
The DTLS code, notably, assumes BIO_wpending to only report what's in
the buffer BIO. Ideally we'd get rid of the buffer BIO (I'll work on
this next), but, in the meantime, get the sizing right. The immediate
motivation is ssl_test using a BIO pair for DTLS doesn't work. We've
just been lucky none of the tests have been near the MTU.
The buffer BIO is actually unused outside of the SSL stack, so this
shouldn't break external consumers. But for the base64 BIO consumer
mentioned above, I see nothing else which relies on this BIO_[w]pending
chaining.

Get one step closer to removing the dependency on |BN_div| from most
programs. Also get one step closer to a constant-time implementation of
|BN_MONT_CTX_set|; we now "just" need to create a constant-time variant
of |BN_mod_lshift1_quick|.
Note that this version might actually increase the side channel signal,
since the variance in timing in |BN_div| is probably less than the variance
from the many conditional reductions in the new method.
On one Windows x64 machine, the speed of RSA verification using the new
version is not too different from the speed of the old code. However,
|BN_div| is generally slow on Windows x64 so I expect this isn't faster
on all platforms. Regardless, we generally consider ECDSA/EdDSA
signature verification performance to be adaquate and RSA signature
verification is much, much faster even with this change.
For RSA signing the performance is not a significant factor since
performance-sensitive applications will cache the |RSA| structure and
the |RSA| structure will cache the Montgomery contexts.
