This patch adds a minor test to dovecot-auth-cli to verify that the
check for invalid number of arguments is working as expected.
It's mostly for consistency, as the utility is only used for testing
purposes.
Many areas of the dovecot library are tested via chamuyero scripts, but
these were not being included in the coverage report.
This patch extends the dovecot-auth-cli tests so that they are now
coverage-aware.
This patch adds a new package which implements two basic primitives for
authenticating against dovecot ("user exists", and "check password").
It is still experimental/work in progress.
