SUDO: convert periodical refreshes to be_ptask This removes old sudo timer and simplyfies code a lot. It also allows to manage offline/online state. - Full and smart refresh are disabled when offline. - Full refresh is run immediately when sssd is back online. - Smart refresh is scheduled normally when sssd is back online.

sudo: do full refresh when data provider is back online https://fedorahosted.org/sssd/ticket/1689 Add a online callback if the first full refresh fails due to the provider beeing offline so we can perform the refresh as soon as possible.

sudo: schedule another full refresh in short interval if the first fails https://fedorahosted.org/sssd/ticket/1689 If the first full refresh of sudo rules fails because the data provider is offline, we will schedule another one in 2, 4, ... minutes.

add sdap_sudo_schedule_refresh() Reduces amount of code duplication.

sudo: do not fail if usn value is zero but full refresh is completed https://fedorahosted.org/sssd/ticket/1596 In case that LDAP server contains zero sudo rules, the full refresh completes succussfully and stores current USN value (= 0). But then smart refresh will fail because it takes USN=0 as invalid value.

sudo ldap provider: load host filter configuration on init We need to load host information during provider initialization. Currently it loads only values from configuration files, but it is implemented as an asynchrounous request as it will later try to autodetect these settings (which will need to contact DNS).

sudo ldap provider: pass sudo_ctx instead of id_ctx I had to create a new context structure to store additional information such as ip addresses and hostnames.

sudo ldap provider: return number of downloaded rules in sdap_sudo_refresh_recv()

sudo ldap provider: find highest USN

sudo ldap provider: add new timer API

sudo ldap provider: provide API for full refresh

sudo ldap provider: give sdap_sudo_refresh_send() search and purge filters

Move BUILD_SUDO outside the generic LDAP source files Avoid #ifdefs in the general part of the code
