If we do not get a realm mapping from the krb5.conf or from the Kerberos
library try to guess it from the service hostname. The guessing of the
realm from the service hostname is already implemented in Heimdal. This
makes the behavior of smb_krb5_get_realm_from_hostname() consistent
with both MIT and Heimdal.

MIT krb5 1.9 version of gss_krb5_import_cred() may fail when importing
credentials from a keytab without specifying actual principal.
This was fixed in MIT krb5 1.9.2 (see commit
71c3be093db577aa52f6b9a9a3a9f442ca0d8f20 in MIT krb5-1.9 branch, git
master's version is bd18687a705a8a6cdcb7c140764d1a7c6a3381b5).
Move fallback code to the smb_gss_krb5_import_cred wrapper. We only
expect this fallback to happen with krb5 GSSAPI mechanism, thus hard
code use of krb5 mech when calling to gss_acquire_cred.

Wrap gss_krb5_import_cred() to allow re-implementing it with
gss_acquire_cred_from() for newer MIT versions. gss_acquire_cred_from()
works fine with GSSAPI interposer (GSS-proxy) while
gss_krb5_import_cred() is not interposed yet.
The wrapper has additional parameter, krb5_context handle, to facilitate
with credentials cache name discovery. All our callers to
gss_krb5_import_cred() already have krb5 context handy.

As the principal in the resulting ccache may not match the realm of the
target principal, we need to store the credentials twice.
The caller uses the ccache principal's realm to construct the
search key for the target principal.
If we get administrator@SAMBADOMAIN via the NTLMSSP authentication
and want to do s4u2selfproxy, we'll get ticket for
client realm: SAMBADOMAIN
client name: administrator
server realm: SAMBA.EXAMPLE.COM
server name: cifs/localdc
This is stored in credential cache, but
the caller will use cifs/localdc@SAMBADOMAIN as
target_principal name when it tries to use the
cache.
So also store the ticket as:
client realm: SAMBADOMAIN
client name: administrator
server realm: SAMBADOMAIN
server name: cifs/localdc
Note that it can always happen that the target is not in the clients
realm, so we always deal with changing realm names, so this is not
a s4u2self/proxy specific thing.
