sysdeps: Reassure gcc 8 that we are not overflowing struct sockaddr_un

Using strncpy (buffer, str, strlen (str)) is a "code smell" that
might indicate a serious bug (it effectively turns strncpy into
strcpy), and gcc 8 now warns about it. In fact we avoided the bug
here, but it wasn't at all obvious.

We already checked that path_len is less than or equal to
_DBUS_MAX_SUN_PATH_LENGTH, which is 99, chosen to be strictly less
than the POSIX minimum sizeof(sun_path) >= 100, so we couldn't
actually be overflowing the available buffer.

The new static assertion in this commit matches a comment above the
definition of _DBUS_MAX_SUN_PATH_LENGTH: we define
_DBUS_MAX_SUN_PATH_LENGTH to 99, because POSIX says struct
sockaddr_un's sun_path member is at least 100 bytes (including space
for a \0 terminator). dbus will now fail to compile on
platforms that are non-POSIX-compliant in this way, except for Windows.

We zeroed the struct sockaddr_un before writing into it, so stopping
one byte short of the end of sun_path ensures that we get \0
termination.

test: Skip TCP tests if getaddrinfo doesn't work

For example, this can be the case in bubblewrap or Debian pbuilder after
unsharing the network namespace:

    bwrap \
    --bind / / \
    --dev-bind /dev /dev \
    --bind /dev/shm /dev/shm \
    --bind /dev/pts /dev/pts \
    --unshare-net \
    ${builddir}/test/test-loopback --tap
    ...
    ok 1 /connect/tcp # SKIP Name resolution does not work here:
    getaddrinfo("127.0.0.1", "0", {flags=ADDRCONFIG, family=INET,
    socktype=STREAM, protocol=TCP}): Name or service not known

On some systems this can be circumvented by using nss_wrapper from
<https://cwrap.org/nss_wrapper.html>:

    cat > hosts <<EOF
    127.0.0.1 localhost
    EOF
    bwrap \
    ... \
    env \
    LD_PRELOAD=libnss_wrapper.so \
    NSS_WRAPPER_HOSTS=$(pwd)/hosts \
    ${builddir}/test/test-loopback --tap
    ...
    # listening at tcp:host=127.0.0.1,port=39219,family=ipv4,guid=...

but for systems where that does't work, we should be prepared to skip
the affected tests.

sysdeps-unix: Handle errors from getaddrinfo correctly

getaddrinfo and getnameinfo have their own error-handling convention
in which the library call returns either 0 or an EAI_* error code
unrelated to errno. If the error code is not EAI_SYSTEM, then
the value of errno is undefined (in particular it might be carried
over from a previous system call or library call). Introduce a
new helper function _dbus_error_from_gai() to handle this.

The equivalent code paths in Windows appear to be OK: the Windows
implementation of getaddrinfo() is documented to return a Winsock
error code, which we seem to be handling correctly.

DBusPendingCall: Only update ->completed under the connection lock

If one thread is blocking on a pending call, and another thread is
dispatching the connection, then we need them to agree on the value
of the completed flag by protecting all accesses with a lock. Reads
for this member seem to have the connection lock already, so it's
sufficient to make sure that the only write also happens under the
connection lock.

We already set the completed flag before calling the callback, so it
seems OK to stretch it to meaning that some thread has merely *taken
responsibility for* calling the callback.

The completed flag shares a bitfield with timeout_added, but that
flag is protected by the connection lock already.

Modify systemd tmpfiles.d snippet to create /var/lib/dbus/

This snippet was already attempting to create /var/lib/dbus/machine-id,
but would fail on volatile or stateless systems where /var/lib/dbus/
did not already exist. systemd-tmpfiles automatically creates parent

Merge remote-tracking branch 'github/dbus-1.12' into dbus-1.12

_dbus_server_new_for_socket: Iterate over arrays as intended

Commit 0c03b505 was meant to clear all the fds indexed by j in
[0, n_fds), which socket_disconnect() can't be allowed to close
(because on failure the caller remains responsible for closing them);
but instead it closed the one we failed to add to the main loop
(fd i), repeatedly.

Similarly, it was meant to invalidate all the watches indexed by j
in [i, n_fds) (the one we failed to add to the main loop and the ones
we didn't try to add to the main loop yet), which socket_disconnect()
can't be allowed to see (because it would fail to remove them from
the main loop and hit an assertion failure); but instead it invalidated
fd i, repeatedly.

These happen to be the same thing if you only have one fd, resulting
in the test-case passing on an IPv4-only system, but failing on a
system with both IPv4 and IPv6.
