0c542dcd3d client: shorten default timeout with localhost and async resolving 
When chronyd is compiled with asynchronous name resolving, it should
always respond quickly. Shorten the default chronyc timeout for
localhost.

5483567190 nameserv: add asynchronous resolving with POSIX threads 
Run getaddrinfo()/gethostbyname() in separate thread to avoid blocking.
Only one resolving thread is running at one time, so this should work
also on systems where the functions are not thread-safe.

6ee357d230 ntp: use async name resolving for NTP sources 
Use the new asynchronous call to resolve addresses of NTP servers
configured by the server/peer directives. Introduce a callback to be
notified when the first resolving attempt ends to correctly finish
chronyd initialization (dumpfile reload and reference mode end).

779e40ed66 ntp: delay initial transmission until first resolving ends 
This will be needed to prevent loading of dump files after sources have
already accumulated samples and possibly reference was already updated
when async resolving of sources is implemented.

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.

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.

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.
