Change to v1

PAM Supports binary conversations using private protocols, this
can be handled by C but it's not supported here because we
implicitly convert all the messages to string, and this may lead
to issues when this is not the case (as in binary protocol the
pointer could contain zeros that the GoString conversion would
consider them the end of the message).

So, add another conversation handler implementation that allows
to handle the binary protocol, whose function callback accepts
a pointer to the struct (we can't use bytes as the length is
unknown and may be defined in the header of the pointer itself).

However since the binary prompt is not supported by all the
platform we need to do a compile-time check to disable it in
case is used when not supported.

 Go PAM can also used to create PAM modules in a simple way, using the go.
