On the client we'll leave it off by default until the change has made it
through Chrome's release process. For TLS 1.3, there is no existing
breakage risk, so always do it. This saves us the trouble of having to
manually turn it on in servers.

The same error in https://crbug.com/368351 implies we're actually
causing the compiler to make some assumptions it shouldn't make. The
obvious fix of marking things as visible causes crashes when built with
ASan (ASan's malloc interceptors and ours are conflicting somehow).
Revert this for now. We should study how ASan's interceptors work and
figure out how to make these two coexist.

This clears the last of Android's build warnings from BoringSSL. These
pragmas aren't actually no-ops, but it just means that MinGW consumers
(i.e. just Android) need to explicitly list the dependency (which they
do).
There may be something to be said for removing those and having everyone
list dependencies, but I don't really want to chase down every
consumer's build files. Probably not worth the trouble.

This releases memory associated with them after the handshake. Note this
changes the behavior of |SSL_get0_certificate_types| and
|SSL_get_client_CA_list| slightly. Both functions now return NULL
outside of the handshake. But they were already documented to return
something undefined when not called at the CertificateRequest.
A survey of callers finds none that would care. (Note
SSL_get_client_CA_list is used both as a getter for the corresponding
server config setter and to report client handshake properties. Only the
latter is affected.) It's also pretty difficult to imagine why a caller
would wish to query this stuff at any other time, and there are clear
benefits to dropping the CA list after the handshake (some servers send
ABSURDLY large lists).
