Add APIs for custom X509_LOOKUP_METHOD creation
OpenSSL 1.1.0 made the X509_LOOKUP_METHOD structure opaque, so
applications that were previously able to define a custom lookup method
are not able to be ported.
This commit adds getters and setters for each of the current fields of
X509_LOOKUP_METHOD, along with getters and setters on several associated
opaque types (such as X509_LOOKUP and X509_OBJECT).

It provides a set of functions used by OpenSSL for the +implementation of various X509 and X509_CRL lookup capabilities. One instance +of an X509_LOOKUP_METHOD can be associated to many instantiations of an +B<X509_LOOKUP> structure. + +X509_LOOKUP_meth_new() creates a new B<X509_LOOKUP_METHOD> structure. It should +be given a human-readable string containing a brief description of the lookup +method. + +X509_LOOKUP_meth_free() destroys a B<X509_LOOKUP_METHOD> structure. + +X509_LOOKUP_get_new_item() and X509_LOOKUP_set_new_item() get and set the +function that is called when an B<X509_LOOKUP> object is created with +X509_LOOKUP_new(). If an X509_LOOKUP_METHOD requires any per-X509_LOOKUP +specific data, the supplied new_item function should allocate this data and +invoke X509_LOOKUP_set_method_data(). + +X509_LOOKUP_get_free() and X509_LOOKUP_set_free() get and set the function +that is used to free any method data that was allocated and set from within +new_item function. + +X509_LOOKUP_meth_get_init() and X509_LOOKUP_meth_set_init() get and set the +function that is used to initialize the method data that was set with +X509_LOOKUP_set_method_data() as part of the new_item routine. + +X509_LOOKUP_meth_get_shutdown() and X509_LOOKUP_meth_set_shutdown() get and set +the function that is used to shut down the method data whose state was +previously initialized in the init function. + +X509_LOOKUP_meth_get_ctrl() and X509_LOOKUP_meth_set_ctrl() get and set a +function to be used to handle arbitrary control commands issued by +X509_LOOKUP_ctrl(). The control function is given the X509_LOOKUP +B<ctx>, along with the arguments passed by X509_LOOKUP_ctrl. B<cmd> is +an arbitrary integer that defines some operation. B<argc> is a pointer +to an array of characters. B<argl> is an integer. B<ret>, if set, +points to a location where any return data should be written to. How +B<argc> and B<argl> are used depends entirely on the control function. + + +X509_LOOKUP_set_get_by_subject(), X509_LOOKUP_set_get_by_issuer_serial(), +X509_LOOKUP_set_get_by_fingerprint(), X509_LOOKUP_set_get_by_alias() set +the functions used to retrieve an X509 or X509_CRL object by the object's +subject, issuer, fingerprint, and alias respectively. These functions are given +the X509_LOOKUP context, the type of the X509_OBJECT being requested, parameters +related to the lookup, and an X509_OBJECT that will receive the requested +object. + +Implementations should use either X509_OBJECT_set1_X509() or +X509_OBJECT_set1_X509_CRL() to set the result. Any method data that was +created as a result of the new_item function set by +X509_LOOKUP_meth_set_new_item() can be accessed with +X509_LOOKUP_get_method_data(). The B<X509_STORE> object that owns the +X509_LOOKUP may be accessed with X509_LOOKUP_get_store(). Successful lookups +should return 1, and unsuccessful lookups should return 0. + +X509_LOOKUP_get_get_by_subject(), X509_LOOKUP_get_get_by_issuer_serial(), +X509_LOOKUP_get_get_by_fingerprint(), X509_LOOKUP_get_get_by_alias() retrieve +the function set by the corresponding setter. + +=head1 RETURN VALUES + +The B<X509_LOOKUP_meth_set> functions return 1 on success or 0 on error. + +The B<X509_LOOKUP_meth_get> functions return the corresponding function +pointers. + +=head1 SEE ALSO + +L<X509_STORE_new(3)>, L<SSL_CTX_set_cert_store(3)> + +=head1 HISTORY + +The functions described here were added in OpenSSL 1.1.0i. + +=head1 COPYRIGHT + +Copyright 2018 The OpenSSL Project Authors.
