On Windows a file descriptor is an int value allocated by the
local module instance of the C Run Time Library. A socket handle is a
SOCKET value allocated by a Winsock Provider for the requested family and
protocol. These two values cannot be mixed and there is no mechanism for
converting between the two. The _get_osfhandle() and _open_osfhandle()
functions can work with a standard HANDLE (file, pipe, etc) but cannot be
used for a SOCKET.
The Heimdal krb5_storage_from_fd() routine counted on the osf conversion
functions working on SOCKET values. Since they do not any attempt to call
krb5_storage_from_fd() on a socket resulted in an assertion being thrown
by the C RTL.
Another problem is SOCKET value truncation when storing a 64-bit value
into a 32-bit int.
To address these problems a new krb5_storage_from_socket() routine is
introduced. This routine setups a krb5_storage that stores a socket value
as a rk_socket_t and provides a set of helper routines that always use
network ready functions.
The krb5_storage_from_fd() routines no longer use net_read() and
net_write() but provide helpers that follow their logic so that pipes can
be processed.
All call sites that allocate a socket now store the socket as rk_socket_t
and call krb5_storage_from_socket().
All locations that previously called the bare close() on a socket value
now call rk_closesocket().

kadm5_c_destroy did not use rk_closesocket when cleaning up
the context. This results in an exception on Windows since a
socket is not a file descriptor.

In the previous implementation when .k5login or .k5login.d existed
and k5login_authoritative was false, no further plugins were tried.
Also when k5login_authoritative was true and .k5login did not match,
the directory was never tried.
mechanism credentials created by dynamically loaded mechanisms do not work
because the gm_mech_oid field is unset for such mechanisms (instead, only
gm_mech.gm_mech_oid is).
In order to support plugins for kadmin that use libkadm5srv, the
libkadm5clnt library has to be versioned to avoid hijacking all
of the function calls that should go to the server library. Omit
the _kadm5_ clients from the public interface, and version
everything else.

The first enctype RFC3961 prf output length's bytes are correct because
the little- and big-endian representations of unsigned zero are the
same. The second block of output was wrong because the counter was not
being encoded as big-endian.
This change could break applications. But those applications would not
have been interoperating with other implementations anyways (in
particular: MIT's).
The use of the wrong value for the length of ":mkey=" was identified
by Brian May and reported via github:

Modify the signature of mp_find_prime() to permit the number of
Miller-Rabin rounds to be specified. In addition, valid responses
now include MP_NO, MP_YES, and MP_VAL which is returned when
mp_prime_is_prime() fails.

libtommath protects the inclusion of functions by wrapping their
declarations by CPP #ifdef tests and defining the matching macros
within libtommath_class.h.
Add missing macros:
BN_MP_FIND_PRIME_C
BN_MP_ISPRIME_C
