Moved authentication specific calls scattered all over the

code to one place: libmuauth library. The new code returns
authorization credentials in struct mu_auth_data. It contains
all information from struct passwd as well as some
mailutils-specific information. New options `--authentication'
and `--authorization' provide a way to override default
settings.
