Sometimes it is useful to set a 'floor' on the TTL for records
to be cached. Some sites like to use ridiculously low TTLs for
some reason, and that often is not compatible with slow links.

While implementing the new unit testing framework cmocka, it was found that the
BIND 9 code doesn't compile when assertions are disabled or replaced with any
function (such as mock_assert() from cmocka unit testing framework) that's not
directly recognized as assertion by the compiler.
This made the compiler to complain about blocks of code that was recognized as
unreachable before, but now it isn't.
The changes in this commit include:
* assigns default values to couple of local variables,
* moves some return statements around INSIST assertions,
* adds __builtin_unreachable(); annotations after some INSIST assertions,
* fixes one broken assertion (= instead of ==)
Tell the user explicitly about their mistakes:
* Unknown options, e.g. -list instead of -dump
or -delete instead of -remove.
* Unknown view names.
* Excess arguments.
Include the view name in `rndc nta -dump` output, for consistency with
the NTA add and remove actions.
When removing an NTA from all views, do not abort with an error if the
NTA was not found in one of the views.
At the beginning of qname minimization we get fctx->finds filled with what's
in the cache at this point, in worst case root servers. After doing full
run querying for NSes at different levels we need to clean it and refill
it with proper values from cache.
Remove the following functions in order to simplify socket code:
- isc_socket_recvv()
- isc_socket_sendtov()
- isc_socket_sendtov2()
- isc_socket_sendv()
