Bug in gss_krb5_ccache_name

[Ezra Peisach]

Thanks you for reporting that. Yes - there is a problem with that code.

strdup is the right way to fix the problem - but we also need a
free function. Perhaps gss_krb5_free_ccache_name - which is essentially
a wrapper for free - but needs to be in the same memory pool as the gssapi 
library...

So - do people like the name gss_krb5_free_ccache_name() or does
someone have something better?
