large numbers of open files. Move krb5int_cm_call_select() to a
separate file so that the poll support doesn't interfere with
net-server.c's continuing use of select.

Restructure the locate_kdc and sendto_kdc code to defer getaddrinfo
calls until we need the answer. This requires many changes:
* struct addrlist is now called struct serverlist, and is declared in
os-proto.h instead of k5-int.h. It contains an array of struct
server_entry structures which can hold either a name or an address.
(Address entries are used for locate_kdc module results.)
* The connection state list is now a linked list, and holds address
information directly instead of using a struct addrinfo (this
simplifies memory management). Each connection entry contains a
callback buffer (previously stored in a separate array) and an index
into the server list.
* The {addrstate} trace formatting primitive is no longer needed, and
has been replaced by {connstate}. There is also a new tracing event
for resolving hostnames.
* locate_server, locate_kdc, free_serverlist, and sendto get their
prefixes changed from krb5int_ to k5_ as their prototypes were being
adjusted anyway. The family argument is gone from the locate
functions as it was never productively used. k5_sendto now receives
the socket types of interest.
* krb5_sendto_kdc will now pass a 0 socktype to k5_locate_kdc if both
socket types are wanted. There were some allowances for this in
locate but this was never previously done. In order to be
conservative when invoking locate modules, we always pass an
explicit socktype, thus calling lookup twice (as we did before,
albeit with a separate init/fini cycle) in the common case. When
creating hostname entries in serverlist from profile configuration,
we preserve the 0 value of socktype, and later create both TCP and
UDP addresses from the getaddrinfo results when the host is
resolved.
* Some accessor functions previously used by libkrb4 have been removed
as they impinged upon this work.

Add trace logging infrastructure code, enabled by the KRB5_TRACE
environment variable or the API functions krb5_set_trace_callback()
or krb5_set_trace_filename(). As a start, add tracing events for:
* AS-REQ client code, including FAST and preauth
* TGS-REQ client code
* AP-REQ and AP-REP code (client and server)
* sendto_kdc
* Selected ccache operations
* Selected keytab operations

Exclude include/gssrpc due to its Sun origin and k5-platform.h due to
macros too hairy for emacs c-mode to handle.

* include/cm.h (state_strings, enum conn_states, struct incoming_krb5_message,
struct conn_state): Moved here from lib/krb5/os/sendto_kdc.c.
(stuct sendto_callback_info): New type.
* lib/krb5/os/sendto_kdc.c (set_conn_state_msg_length): New function.
(setup_connection): Deleted argument message_len_buf. Don't store message
length; call set_conn_state_msg_length instead.
(start_connection): New arguments callback_info and callback_buffer. Invoke
callback function if any, and set message length on success.
(maybe_send): New arguments callback_info and callback_buffer; pass them to
start_connection.
(krb5int_sendto): New arguments callback_info, remoteaddr, remoteaddrlen. If
callback info is provided, allocate per-connection buffers, and pass them to
maybe_send. On cleanup, invoke the cleanup callback function if any.
(krb5_sendto_kdc): Update krb5int_sendto call.
* include/k5-int.h (struct sendto_callback_info): Add forward declaration.
(krb5int_sendto, struct _krb5int_access.sendto_udp): Update for new signature.
* lib/krb5/os/send524 (krb5int_524_sendto_kdc): Update krb5int_sendto call.
* lib/krb4/send_to_kdc.c (krb5int_send_to_kdc_addr): Update sendto_udp call.
* lib/krb5/os/changepw.c (struct sendto_callback_context): New type.
(krb5_locate_kpasswd): New argument useTcp, used to select socket type in
krb5int_locate_server call.
(kpasswd_sendto_msg_cleanup, kpasswd_sendto_msg_callback): New functions.
(krb5_change_set_password): Call krb5int_sendto with callbacks, instead of
managing the exchange here. On RESPONSE_TOO_BIG error, try again with TCP
only.
* lib/krb5/krb/chpw.c (krb5int_rd_chpw_rep): If length is wrong, check if a
buggy server sent a KRB_ERROR.
