TS_OBJ_print_bio() misuses OBJ_txt2obj: it should print the result

length the complete text reprsentation would need not the amount of
data written.

There are two failure cases for OCSP_request_add_id():
1. OCSP_ONEREQ_new() failure, where |cid| is not freed
2. sk_OCSP_ONEREQ_push() failure, where |cid| is freed
This changes makes the error behavior consistent, such that |cid| is
not freed when sk_OCSP_ONEREQ_push() fails. OpenSSL only takes
ownership of |cid| when the function succeeds.

Operations in the DSA signing algorithm should run in constant time in
order to avoid side channel attacks. A flaw in the OpenSSL DSA
implementation means that a non-constant time codepath is followed for
certain operations. This has been demonstrated through a cache-timing
attack to be sufficient for an attacker to recover the private DSA key.

If the string to print is exactly 2048 character long (excluding the NULL
terminator) then BIO_printf will chop off the last byte. This is because
it has filled its static buffer but hasn't yet allocated a dynamic buffer.
In cases where we don't have a dynamic buffer we need to truncate but that
is not the case for BIO_printf(). We need to check whether we are able to
have a dynamic buffer buffer deciding to truncate.
