subject: krb5_fcc_resolve file locking error on malloc failuer

In krb5_fcc_resolve, on malloc failure, the data->lock mutex needs to
be destroyed. Unfortunately, this is done with the mutex is still locked. When thread debugging code is enabled, this results in aeg fault. 

Also - in krb5_fcc_generate_new, a strdup failure would result in the
krb5int_cc_file_mutex being unlocked twice.

[I have a modified version of valgrind in which I can signal after a
certain number of mallocs for it to fail - I vary the allocation
number from 1300 to 0 - and see what breaks - some memory leaks will
be fixed separately]
