In the RSA_X931_derive_ex a call to BN_CTX_new is made. This can return
NULL on error. However the return value is not tested until *after* it is
derefed! Also at the top of the function a test is made to ensure that
|rsa| is not NULL. If it is we go to the "err" label. Unfortunately the
error handling code deref's rsa.

lead to a NULL deref in the event of a malloc failure. Also fixed a mem

ASN1_primitive_new takes an ASN1_ITEM * param |it|. There are a couple
of conditional code paths that check whether |it| is NULL or not - but
later |it| is deref'd unconditionally. If |it| was ever really NULL then
this would seg fault. In practice ASN1_primitive_new is marked as an
internal function in the public header file. The only places it is ever
used internally always pass a non NULL parameter for |it|. Therefore, change
the code to sanity check that |it| is not NULL, and remove the conditional
checking.

The rationale for this move is that TERMIOS is default, supported by
POSIX-1.2001, and most definitely on Linux. For a few other systems,
TERMIO may still be the termnial interface of preference, so we keep
-DTERMIO on those in Configure.
crypto/ui/ui_openssl.c is simplified in this regard, and will define
TERMIOS for all systems except a select few exceptions.
