configure: make NTP and ASYNCDNS support nonoptional

Don't allow the NTP support and asynchronous name resolving to be
disabled. pthreads are now a hard requirement.

NTP is the primary task of chrony. This functionality doesn't seem to be
commonly disabled (allowing only refclocks and manual input).

This removes rarely (if ever) used code and simplifies testing.

extra library is needed. The default user which `chronyd` should run as can be
specified with the `--with-user` option of the `configure` script.
If development files for the POSIX threads library are available, `chronyd`
will be built with support for asynchronous resolving of hostnames specified in
the `server`, `peer`, and `pool` directives. This allows `chronyd` operating as
a server to respond to client requests when resolving a hostname. If you don't
want to enable the support, specify the `--disable-asyncdns` flag to
`configure`.
