[krbdev.mit.edu #2049] Windows: Add new krb5_ccache type MSLSA: for read-only access to MS Credential Cache

[Jeffrey Altman via RT]

Our experience has shown that end users who attempt to make use of the
MS Kerberos LSA cache in their applications inevitably get it wrong.
Especially because the behavior of the LSA is slightly different on 
each of the different operating systems.  We have seen many people 
copying/pasting code from src/windows/ms2mit.c into their apps where
it cannot be readily fixed when problems arise.  We have a similar 
problem in that both KfW Leashw32.dll and ms2mit.exe both have to share
similar code.  For 1.3.2 we will create a new krb5_ccache type which 
can be used for credential access from ms2mit.exe, leashw32.dll, and 
end user applications.
