fixes killing the server with SIGKILL causing abortiong,
added SIGTERM handler and ignored retcode from uv_run()

- the test driver now waits for daemon to accept TCP
- workaround cwrap bug, Python prebinds to daemon sockets to create files
- tested daemon runs in the testdir
- test driver doesn’t kill all kresd processes

- no need to bind to client socket
- relying on short timeouts is bad
- no check for send buffers overflow

this is a workaround, as we don't support `make uninstall` yet

zonecut should be able to hold these for testing reasons (like private
root or zone cut), but it should filter out data from the internet
a new flag: QUERY_ALLOW_LOCAL allows for being more permissive, and
letting name server query local or private address ranges

this is not documented atm as it is going to change for a module with
declarative interface and less cryptic names

this is a small step for me, but a huge step for resolver

based on _BSD_SOURCE timersub macro

this fixes stats for canceled/blocked or forwarded queries without
started name resolution

this also fixes static linking missing a math library
