More KfM merge work
Create new file FSp-glue.c including KfM functions that had previously
been scattered through various other files.
Port RealmsConfig-glue.c from KfM, including old Unix-ish krb4
configuration code as fallback. Remove other files containing old
realm/config file support.
Add KRB5_CALLCONV to krb_get_in_tkt_creds.
Fix various functions to take const char* as arguments now that
tkt_string() returns const.
Assorted minor cleanup.
Implement krb_get_err_text in terms of com_err. Implement gross
kludge to force krb_err_txt to remain in sync with com_err.
