David Lawrence ce2be9b721 329. [func] omapi_auth_register() now takes a size_t argument for
the length of a key's secret data.  Previously
			OMAPI only stored secrets up to the first NUL byte.

This change was made to cope with decoded base64 secrets, so in this
revision omapiconf.c and rndc.c also decode the secret.
