ed96b4d49d nameserv: prepare for asynchronous resolving 
Introduce a new function with callback to resolve names to IP addresses
asynchronously. For now, use a blocking wrapper around DNS_Name2IPAddress.

8671002bd7 sources: add flag that source is active 
When source is set as active, it's receiving reachability updates (e.g.
offline NTP sources are not active).

Also add function to count active sources.

bc6b40568d ntp: reduce burst timeout to 2.0 
With the new special mode ending it can be now equal to the burst

3888b9dcec sources: rework special mode ending with unreachable sources 
Instead of giving up when a source has 7 reach updates, continue as long
as at least one source has fewer than 7 updates and can still have 3
samples to be selectable in that number of updates.

When no sources are responding, it will give up sooner.

5cb7e6c9c3 sched: fix main loop to allow timeout handlers modify fd set or quit 
With special reference update modes, the timeout handlers may add or
remove file descriptors from the read fd set, so it needs to be copied
for select() call after they are dispatched. Also, they can now request
quit, so the exit flag needs to be checked before select() to avoid
hanging.

ff31702f74 configure: add option to set default user

the user.

70928dba52 ntp: set maximum number of iburst samples to size of reach register 
Explicitly set the number of iburst samples to the size of the register
to make sure there are at least 7 reachability updates and the
initstepslew mode can be ended.

7fda9c6723 ntp: drop initstepslew NTP implementation 
The initstepslew code has its own minimal NTP implementation. Drop the
code, add a new initstepslew mode to the reference updating code and
use regular NTP sources with iburst flag for initstepslew addresses
instead. When an update is made or a source is found unreachable, log a
message, remove the initstepslew sources and switch to normal mode.

This reduces code duplication and makes initstepslew use features
implemented only in the main code like source combining or SO_TIMESTAMP
support.

5c2bbaca3b ntp: use separate client sockets 
Use separate sockets for NTP server or peer and client packets. The port
number is configured by the acquisitionport directive. With the default
value of 0 the port is assigned randomly by the kernel. It can be equal
to the value configured by the port directive to use the server sockets
for all packets as before.
