Add a minimal implementation of the PAM ssh-agent module, hook up all the
build and test infrastructure, add minimal tests for arguments validation.
The module is built as shared object, PIC versions of libssh and
libopenbsd-compat are therefore built if needed.
Testing is based on pam_wrapper and is enabled only if the required
libraries and headers are found during configuration.
During test ssh keys of various types are used. The ktype.sh script is
split so to reuse the keys generation part.
The module is not built by default.
