Subject: [PATCH] Fix object searching by label
Removed checking whether obj_id is not NULL, because obj_id is a stack
pointer declared as "unsigned char obj_id[MAX_VALUE_LEN / 2]".
Removed checking whether *obj_id is not (unsigned char)0, because this
is an uninitialized stack memory reference unless an "id" value was
provided in the URI.

Subject: [PATCH 4/4] When ID and label are specified, both need to match, not
either.
To fix this id-match OR label-match was replaced with id-match AND
label-match.
A tiebreak was added when multiple matching certificates could be
returned. The certificate with the latest expiry wins, and if we
still have a tie we deterministically choose a certificate using
X509_cmp().
If we do not specify a certificate, we return the first certificate
(or first certificate with an ID) as before.
Debug logging updated to show the expiry date used in the decision.

Subject: [PATCH 1/2] add re-numeration of slots as engine ctrl command
This was broken in 14cd0d328fff96b79fabcc30257e358399c8ad25.
Previously, the engine would re-enumerate before loading keys/certs
Not re-enumerating the slots results in un-awareness of changes in slots
and tokens.
This awareness is required to be able to change the token in a slot at
runtime, else you use invalid sessions
(PKCS#11 module:pkcs11_find_keys:Session handle invalid:p11_key.c:512)
The patch adds the command RE_ENUMERATE as engine control, providing the
ability to re-enumerate on demand/when required.

Subject: [PATCH] Simplify engine code to load certificates, public and private
keys
It was mostly copy paste, so remove the duplicate code to simplify
code maintenance and readability. The per-slot object matching code
is made a callback because the internally cached structs do not
share a common header portion. Make the helper functions do as much
as possible to minimize duplicate code.
