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.
