list: Define new API virConnectListAllSecrets

This is to list the secret objects. Supports to filter the secrets
by its storage location, and whether it's private or not.

include/libvirt/libvirt.h.in: Declare enum virConnectListAllSecretFlags
                              and virConnectListAllSecrets.
python/generator.py: Skip auto-generating
src/driver.h: (virDrvConnectListAllSecrets)
src/libvirt.c: Implement the public API
src/libvirt_public.syms: Export the symbol to public

+ * @secrets: Pointer to a variable to store the array containing the secret
+ *           objects or NULL if the list is not required (just returns the
+ *           number of secrets).
+ * @flags: extra flags; not used yet, so callers should always pass 0
+ *
+ * Collect the list of secrets, and allocate an array to store those
+ * objects.
+ *
+ * Normally, all secrets are returned; however, @flags can be used to
+ * filter the results for a smaller list of targeted secrets. The valid
+ * flags are divided into groups, where each group contains bits that
+ * describe mutually exclusive attributes of a secret, and where all bits
+ * within a group describe all possible secrets.
+ *
+ * The first group of @flags is used to filter secrets by its storage
+ * location. Flag VIR_CONNECT_LIST_SECRETS_EPHEMERAL selects secrets that
+ * are kept only in memory. Flag VIR_CONNECT_LIST_SECRETS_NO_EPHEMERAL
+ * selects secrets that are kept in persistent storage.
+ *
+ * The second group of @flags is used to filter secrets by privacy. Flag
+ * VIR_CONNECT_LIST_SECRETS_PRIVATE seclets secrets that are never revealed
+ * to any caller of libvirt nor to any other node. Flag
+ * VIR_CONNECT_LIST_SECRETS_NO_PRIVATE selects non-private secrets.
+ *
+ * Returns the number of secrets found or -1 and sets @secrets to NULL in case
+ * of error.  On success, the array stored into @secrets is guaranteed to
+ * have an extra allocated element set to NULL but not included in the return count,
+ * to make iteration easier.  The caller is responsible for calling
+ * virSecretFree() on each array element, then calling free() on @secrets.
