* Anonymous pkinit responses from the KDC where the name
type is not well-known (as issued by 7.5 KDCs and earlier)
are accepted by the client. There is no need for the client
to strictly enforce the name type.
* With historical_anon_pkinit = true, the kinit(1) client's
"--anonymous" option only performs anon pkinit, and does
not require an '@' prefix for the realm argument.
* With historical_anon_realm = true, the KDC issues anon
pkinit tickets with the legacy pre-7.0 "real" realm.
MIT prefers underscores in ccache configuration file keys, so in the interest
of future interoperability use anon_pkinit_realm instead of anon-pkinit-realm
when storing the anonymous PKINIT TGS realm.
Anonymous PKINIT tickets discard the realm information used to locate the
issuing AS. Store the issuing realm in the credentials cache in order to locate
a KDC which can renew them.
_krb5_principal_is_anonymous() is used outside lib/krb5 and
therefore it needs to be properly exported and its flag macros
need to be in a public header: krb5.h not krb5_locl.h.
Including krb5_locl.h from within kuser_locl.h for instance
results in build failures on Solaris.
This change renames the function and makes it part of the public
api.

Add macros to give symbolic names to the flags which can be passed to
krb5_get_init_creds_opt_set_pkinit(). Reserve flags for BTMM and not validating
KDC anchors.
Add _krb5_principal_is_anonymous() private API for checking if a principal is
anonymous or not. The third argument determines whether to match authenticated
anonymous, unauthenticated anonymous, or both types of principal.
The meaning of the two is different and we should
not implicitly set both if one was requested (this
aligns the logic with MIT kinit -C/-E options).

kinit does not destroy ccaches created with krb5_cc_new_unique() if ticket
acquisition fails. This was leaving dangling keyring entries with the keyring
ccache.
In 13c8a2c212 permits fclose() to
be issued on 'stdin' and forgets to use the N_() macro for text
strings.

Instead of imposing a default 10 hour ticket lifetime and 1 month renew
lifetime when requesting tickets, increase the default lifetime and
renew lifetime to 2147483647 seconds. This ensures that in the absence
of any other configuration or command line parameters that the KDC will
determine the ticket lifetime and renew lifetime.

This is needed so that the NTLM GSS mechanism can have a meaningful
concept of default credential (the NTLM key for the default domain found
in the ccache).
Provide a new internal function called get_switched() to encapsulate
the algorithm for selecting a credential cache when the selected
ccache type supports switching. There is no change in behavior for
UNIX which always calls krb5_cc_new_unique(). However, on Windows
alternate behavior is provided when the ccache type is API or MSLSA.
For the API ccache the default ccache name is stored in the Windows
registry which is shared across all logon sessions belonging to a
user. For users that are members of the Administrators group this
includes both the UAC restricted and elevated sessions sharing the
same desktop. It is very disconcerting when the elevated session obtains
credentials for the same client principal as the restricted session
and then all apps in the restricted session lose access to their
credential cache. For Windows, the API credential caches are named
after the principal that is stored within them. It provides for a
better end user experience.
For the MSLSA ccache tickets belonging to multiple principals are
all stored within the MSLSA ccache. As a result, all attempts to
switch ccache names default back to the one and only one name.

When PAM is configured to use a user_realm that is different from the
default realm, do likewise in kinit with bare user names or the default
principal computed from the login name.
Similarly, when using a keytab, if no realm is specified find the most
suitable match in the keytab file.
1. in ticket_lifetime() calculate the remaining lifetime
of the ticket rather than the requested lifetime.
2. in renew_func(), attempt to renew if the tickets are
renewable rather than only if --renewable is specified.
3. fix the call to renew_validate() in renew_func() to
specify renewable tickets if the original tickets are
renewable rather than only if --renewable is specified.
4. stop printing constant warnings to the terminal about
how tickets cannot be obtained if they expire, cannot
be renewed and we can't non-interactively obtain fresh
ones. We limit it to a single warning.
5. after the tickets expire, we backoff the requests to
obtain fresh tickets exponentially.
We turn on a few extra warnings and fix the fallout that occurs
when building with --enable-developer. Note that we get different
warnings on different machines and so this will be a work in
progress. So far, we have built on NetBSD/amd64 5.99.64 (which
uses gcc 4.5.3) and Ubuntu 10.04.3 LTS (which uses gcc 4.4.3).
Notably, we fixed
1. a lot of missing structure initialisers,
2. unchecked return values for functions that glibc
marks as __attribute__((warn-unused-result)),
3. made minor modifications to slc and asn1_compile
which can generate code which generates warnings,
and
4. a few stragglers here and there.
We turned off the extended warnings for many programs in appl/ as
they are nearing the end of their useful lifetime, e.g. rsh, rcp,
popper, ftp and telnet.
Interestingly, glibc's strncmp() macro needed to be worked around
whereas the function calls did not.
We have not yet tried this on 32 bit platforms, so there will be
a few more warnings when we do.
