libpam_internal: introduce pam_line

The pam_assemble_line function is renamed to pam_line_assemble and
moved into libpam_internal so it can be shared across libpam and the
pam_env module.

Applied renaming to all other relevant functions and data structures
so it is easier to locate them in files.
