This is a really dumb API wart. Now that we have a limited set of curves that
are all reasonable, the automatic logic should just always kick in. This makes
set_ecdh_auto a no-op and, instead of making it the first choice, uses it as
the fallback behavior should none of the older curve selection APIs be used.
Currently, by default, server sockets can only use the plain RSA key exchange.

See upstream's bd891f098bdfcaa285c073ce556d0f5e27ec3a10. It honestly seems
kinda dumb for a client to do this, but apparently the spec allows this.
Judging by code inspection, OpenSSL 1.0.1 also allowed this, so this avoids a
behavior change when switching from 1.0.1 to BoringSSL.
Add a test for this, which revealed that, unlike upstream's version, this
actually works with ecdh_auto since tls1_get_shared_curve also needs updating.

The 2 arg OpenSSL sk_find() returned -1 on error and >= 0 on
success. BoringSSL's 3 arg sk_find() returns -1 if the sk argument
is NULL, 0 if the item is not found, and 1 if found.
In practice, all callers of the sk_find() macros in BoringSSL only
check for zero/non-zero. If sk is ever NULL, it looks like most
callers are going to use uninitialized data as the index because
the return value check is insufficient.

slightly trickier. We can make it do something if needbe, but it's probably not

Prior to this, BoringSSL was using OpenSSL's technique of having users
register a callback for locking operation. This change adds native mutex
support.
Since mutexes often need to be in objects that are exposed via public
headers, the non-static mutexes are defined in thread.h. However, on
Windows we don't want to #include windows.h for CRITICAL_SECTION and, on
Linux, pthread.h doesn't define pthread_rwlock_t unless the feature
flags are set correctly—something that we can't control in general
for public header files. Thus, on both platforms, the mutex is defined
as a uint8_t[] of equal or greater size and we depend on static asserts
to ensure that everything works out ok.
