* Makefile.in: Make krb524 library and k524init program build on

* Makefile.in: Make krb524 library and k524init program build on
Windows.

* krb524.def, libinit.c: Files needed to build on Windows.

* k524init.c: Use public krb_in_tkt() with realm paramter instead of
potentially private in_tkt() w/o realm parameter (which does not
even exist w/o the realm paramter in some krb4 libraries).  Use
krb_save_credentials() instead of tf_init() then
tf_save_credentials() then tf_close().

* cnv_tkt_skey.c: Put copy of krb_cr_tkt_krb5() and
krb_create_ticket() as static functions in this file, calling them
krb524int_*().  Call these functions instead of the ones in the
MIT krb4 library included in the krb5 tree.

* conv_princ.c: Remove unused headers.

* k524init.c, cnv_tkt_skey.c, conv_creds.c, encode.c, misc.c,
sendmsg.c, test.c: Do not include Unix headers on Windows.

* sendmsg.c (krb524_sendto_kdc): Fix call to krb5_locate_kdc() to
use right number and types of parameters.  Use krb5int_accessor()
to get at internals: krb5_locate_kdc(), krb5_max_dgram_size,
krb5_skdc_timeout_1, and krb5_skdc_timeout_shift.  (The latter 3
should probably be #defines...)
