Combined patch for the more or less obvious issues
Fixed a memory leak in ASN1_digest and ASN1_item_digest.
asn1_template_noexp_d2i call ASN1_item_ex_free(&skfield,...) on error.
Reworked error handling in asn1_item_ex_combine_new:
- call ASN1_item_ex_free and return the correct error code if ASN1_template_new failed.
- dont call ASN1_item_ex_free if ASN1_OP_NEW_PRE failed.
Reworked error handing in x509_name_ex_d2i and x509_name_encode.
Fixed error handling in int_ctx_new and EVP_PKEY_CTX_dup.
Fixed a memory leak in def_get_class if lh_EX_CLASS_ITEM_insert fails due to OOM:
- to figure out if the insertion succeeded, use lh_EX_CLASS_ITEM_retrieve again.
- on error, p will be NULL, and gen needs to be cleaned up again.

Fix SSL_VERIFY_CLIENT_ONCE
The flag SSL_VERIFY_CLIENT_ONCE is documented as follows:
B<Server mode:> only request a client certificate on the initial TLS/SSL
handshake. Do not ask for a client certificate again in case of a
renegotiation. This flag must be used together with SSL_VERIFY_PEER.
B<Client mode:> ignored
But the implementation actually did nothing. After the server sends its
ServerKeyExchange message, the code was checking s->session->peer to see if
it is NULL. If it was set then it did not ask for another client
certificate. However s->session->peer will only be set in the event of a
resumption, but a ServerKeyExchange message is only sent in the event of a
full handshake (i.e. no resumption).
The documentation suggests that the original intention was for this to
have an effect on renegotiation, and resumption doesn't come into it.
The fix is to properly check for renegotiation, not whether there is already
a client certificate in the session.
As far as I can tell this has been broken for a *long* time.

If an engine comes up explicitely, it must also come down explicitely
In apps/apps.c, one can set up an engine with setup_engine().
However, we freed the structural reference immediately, which means
that for engines that don't already have a structural reference
somewhere else (because it has registered at least one cipher or digest
algorithm method, and therefore gets a functional reference through the
ENGINE_set_default() call), we end up returning an invalid reference.
Instead, the function release_engine() is added, and called at the end
of the routines that call setup_engine().
Originally, the ENGINE API wasn't designed for this to happen, an
engine had to register at least one algorithm method, and was
especially expected to register the algorithms corresponding to the
key types that could be stored and hidden in hardware. However, it
turns out that some engines will not register those algorithms with
the ENGINE_set_{algo}, ENGINE_set_cipher or ENGINE_set_digest
functions, as they only want the methods to be used for keys, not as
general crypto accelerator methods. That may cause ENGINE_set_default()
to do nothing, and no functional reference is therefore made, leading
to a premature deallocation of the engine and it thereby becoming
unavailable when trying to fetch a key.
