Previously, 64-bit (LP64 or LLP64) platforms would have had 32 bits
of padding between pad2 and pad3. We want to guarantee that an ISO C
compiler will copy the entire struct when assigning between structs,
but padding is not guaranteed to be copied, so we want to ensure that
the struct is "packed".

We already asserted that DBusMessageIter must be at least as large
as DBusMessageRealIter (so that casting DBusMessageIter * to
DBusMessageRealIter * does not result in overflowing the stack
variable). Also assert that it must have alignment requirements at
least as strict as those of DBusMessageRealIter * (so that casting
does not increase the required alignment).

The exception is test-autolaunch, which is really not particularly
useful as a build-time test. The only way we can really test
autolaunch is as a whole-system integration test, and "make check"
is not that.
The two tests written in Python and one test based on dbus-send
are also not run directly yet; in particular, that includes both
the tests in run-test-systemserver.sh.

dbus-daemon is not expected to open files with large *sizes*, but without
large file support, calling [f]stat() on a file that happens to have a
large inode number will fail with EOVERFLOW (see stat(2)). For example,
files mounted from an NFS server might have large inode numbers.

The idea is that .travis.yml is specific to Travis-CI, but most of the
actual work is done in tools/ci-build.sh, which should be reasonably
CI-platform-agnostic (it currently assumes that build-dependendencies are
preinstalled, that the "native" platform we're building on is GNU/Linux
or something very close, and that "mingw" means mingw-w64 as packaged
in Debian and Ubuntu).

With --systemd-activation we special-case the name
org.freedesktop.systemd1 by assuming that it will eventually connect
to the bus. With that in mind, we can ignore whether it has a
.service file, and let it be "activated" regardless.
This fixes a regression test failure on non-systemd systems such
as the Ubuntu 14.04 OS on travis-ci.org: UpdateActivationEnvironment
failed, because it tried to update the (fake) systemd environment,
but because systemd was not actually installed, there was no
service file for it in the system's search paths. We could address this
by placing a dummy service file with Exec=/bin/false in our search path
like the real systemd does, but it seems cleaner to not require this;
this would eventually enable the real systemd to stop installing
that dummy service file.
This would not happen outside the regression tests, because there is
no sense in using --systemd-activation without systemd installed.

These tests still do not actually produce TAP output yet; I tried

Since 1.10.4 this is hard-coded to be disallowed when an activation
helper is used. That would be a security flaw waiting to happen,
and makes little sense anyway, because the activation helper sanitises
its environment.
Use BecomeMonitor() instead, as our way to assert that root and
messagebus are privileged.
