Alexander Bokovoy f996c21edb ipa-kdb: add missing prototypes
On Fedora 33 GCC defaults to -Wmissing-prototypes and emits warnings
about function prototypes missing. If -Werror is specified, this breaks
compilation.

We also default to -Werror=implicit-function-declaration

Rob Crittenden a129e6f042 ipa_kdb: Fix memory leak
ipadb_get_principal() allocates client_actual. Call
ipadb_free_principal to release it.

Rather than spreading the free() amongst the code introduce
done as a target to match behavior in similar functions.

Alexander Bokovoy c5f32165d6 Add Authentication Indicator Kerberos ticket policy options
For the authentication indicators 'otp', 'radius', 'pkinit', and
'hardened', allow specifying maximum ticket life and maximum renewable
age in Kerberos ticket policy.

The policy extensions are now loaded when a Kerberos principal data is
requested by the KDC and evaluated in AS_REQ KDC policy check. If one of
the authentication indicators mentioned above is present in the AS_REQ,
corresponding policy is applied to the ticket.

Changmin Teng 15ff9c8fec Implement user pre-authentication control with kdcpolicy plugin
We created a Kerberos kdcpolicy plugin to enforce user
pre-authentication policy for newly added pkinit and hardened policy.

In the past version of freeIPA, password enforcement exists but was done
by removing key data for a principal while parsing LDAP entry for it.
This hack is also removed and is now also enforced by kdcpolicy plugin
instead.
