Yo dawg I herd you like blinding so I put inversion blinding in your
RSA blinding so you can randomly mask your random mask.
This improves upon the current situation where we pretend that
|BN_mod_inverse_no_branch| is constant-time, and it avoids the need to
exert a lot of effort to make a actually-constant-time modular
inversion function just for RSA blinding.
Note that if the random number generator weren't working correctly then
the blinding of the inversion wouldn't be very effective, but in that
case the RSA blinding itself would probably be completely busted, so
we're not really losing anything by relying on blinding to blind the
blinding.

Our CBB patterns do not make it safe to use a CBB after any operation
failed. Suppose one does:
int add_to_cbb(CBB *cbb) {
CBB child;
return CBB_add_u8(cbb, 1) &&
CBB_add_u8_length_prefixed(cbb, &child) &&
CBB_add_u8(&child, 2) &&
/* Flush |cbb| before |child| goes out of scoped. */
CBB_flush(cbb);
}
If one of the earlier operations fails, any attempt to use |cbb| (except
CBB_cleanup) would hit a memory error. Doing this would be a bug anyway,
since the CBB would be in an undefined state anyway (wrote only half my
object), but the memory error is bad manners.
Officially document that using a CBB after failure is illegal and, to
avoid the memory error, set a poison bit on the cbb_buffer_st to prevent
all future operations. In theory we could make failure +
CBB_discard_child work, but this is not very useful and would require a
more complex CBB pattern.

This is the equivalent of FragmentAcrossChangeCipherSuite for DTLS. It
is possible for us to, while receiving pre-CCS handshake messages, to
buffer up a message with sequence number meant for a post-CCS Finished.
When we then get to the new epoch and attempt to read the Finished, we
will process the buffered Finished although it was sent with the wrong
encryption.
Move ssl_set_{read,write}_state to SSL_PROTOCOL_METHOD hooks as this is
a property of the transport. Notably, read_state may fail. In DTLS
check the handshake buffer size. We could place this check in
read_change_cipher_spec, but TLS 1.3 has no ChangeCipherSpec message, so
we will need to implement this at the cipher change point anyway. (For
now, there is only an assert on the TLS side. This will be replaced with
a proper check in TLS 1.3.)

shouldn't happen. Also, our C++ consumers might quite like to have
access to the scoped types.
Thus this change moves some of the template code to base.h and puts it
all in a |bssl| namespace to prepare for scattering these types into
their respective headers. In order that all the existing test code be
able to access these types, it's all moved into the same namespace.

We usually put main at the end. There's now nothing interesting in the
function, so avoid having to declare every test at the top.
