Implement the GSS-API credential store API extensions defined by MIT here: https://k5wiki.kerberos.org/wiki/Projects/Credential_Store_extensions Note: we kill off gss_acquire_cred_ext() here. This was never a public API, although mechanisms could have implemented it and I briefly used it in my BrowserID prototype mechanism. gss_acquire_cred_ext_from() occupies the place in the dispatch table where gss_acquire_cred_ext() used to, but this structure was never visible outside Heimdal (i.e. it is only used by internal mechanisms); (Mechanisms that need to accept arbitrary key/value dictionaries from applications should now implement gss_acquire_cred_from().)
