sd_bus_flush_close_unref() is a call that simply combines sd_bus_flush()
(which writes all unwritten messages out) + sd_bus_close() (which
terminates the connection, releasing all unread messages) +
sd_bus_unref() (which frees the connection).
The combination of this call is used pretty frequently in systemd tools
right before exiting, and should also be relevant for most external
clients, and is hence useful to cover in a call of its own.
Previously the combination of the three calls was already done in the
_cleanup_bus_close_unref_ macro, but this was only available internally.
Also see #327

This patch removes includes that are not used. The removals were found with
include-what-you-use which checks if any of the symbols from a header is
in use.

Stuff in src/shared/ should not use stuff from src/libsystemd/ really.

c > 0 is already guaranteed from earlier checks.
We go from
ms = ALIGN(l+1) +
sizeof(char*) +
(c > 0 ? c : 1) * ALIGN(alen) +
(c > 0 ? c+1 : 2) * sizeof(char*);
to
ms = ALIGN(l+1) +
sizeof(char*) +
c * ALIGN(alen) +
(c+1) * sizeof(char*);
to
ms = ALIGN(l+1) + c * ALIGN(alen) + (c+2) * sizeof(char*);

something up
Also, return on which protocol/family/interface we found something.

Since b5eca3a2059f9399d1dc52cbcf9698674c4b1cf0 we don't attempt to GC
busses anymore when unsent messages remain that keep their reference,
when they otherwise are not referenced anymore. This means that if we
explicitly want connections to go away, we need to close them.
With this change we will no do so explicitly wherver we connect to the
bus from a main program (and thus know when the bus connection should go
away), or when we create a private bus connection, that really should go
away after our use.
This fixes connection leaks in the NSS and PAM modules.

glibc appears to be broken if we don't explicitly reset all error
variables, let's work around that.

That way DNS resolution works both with and without resolved running.

Let's settle on a single type for all address family values, even if
UNIX is very inconsitent on the precise type otherwise. Given that
socket() is the primary entrypoint for the sockets API, and that uses
"int", and "int" is relatively simple and generic, we settle on "int"
for this.

We mostly use "family" to refer to AF_INET, AF_INET6, etc, let's use
this terminology here, too

Also, hook up nss-resolve to make use of this information
