Windows returns unhandled exceptions from a running child
by specific exit codes and not by signals as on UNIX.
Therefore we use DBUS_ERROR_SPAWN_CHILD_EXITED for propagating
unhandled exceptions to the parent too.

We install the symlink to enable dbus.socket statically, so it doesn't
make much sense to invoke `systemctl enable` on it; and
dbus.service should normally be started by socket activation
(or possibly an explicit dependency) rather than manually.

It's generally a good idea to avoid trailing whitespace in order to keep
patchs minimal. While it's common to enforce such restrictions for C code,
it's important for docbok XML files too. Hence, let's clean this up and
remove all trailing whitespace currently in place.
[By policy we do not clean up historical trailing whitespace and
tab-indentation in the C source code unless we are modifying those lines
anyway, to retain the ability to merge stable-branch bugfixes into the
development branch. However, the copy of the spec in the development
branch is the only one that receives any updates, so that concern
doesn't apply here. -smcv]

Allowing to send replies when NO_REPLY_EXPECTED is set is useless in
practice: Clients need to be careful not to send these replies, because
bus policy could deny these messages. The spec even mentions that this
issue exists.
To make this more clear and misbehaving clients less likely, disallow
sending unexpected replies entirely.

Previously, we didn't consistently test parsing of every file in
valid-config-files-system/ everywhere that we tested valid-config-files/.
We now test it on Unix.
The system bus is not supported on Windows, so we do not test
valid-config-files-system/ there.
valid-config-files/many-rules.conf contains <user> and <group> rules
which are not applicable to Windows. Copy the original many-rules.conf
to valid-config-files-system/ so that it will be tested on Unix, and
remove the non-portable rules from valid-config-files/many-rules.conf.

Under Wine, the API calls we use to do this are implemented via IPC
to wineserver, which makes it unreasonably slow to try to brute-force
bugs by having many threads stress-test refcounting. Do a few
repetitions just to verify that refcounting basically works, but
don't do the full stress-test.

If the user gave us a syntactically invalid error name, we'd
overwrite the MatchRuleInvalid error with NoMemory, causing an
assertion failure (crash) in the dbus-daemon.
This is not a denial-of-service vulnerability on the system bus,
because monitoring is a privileged action, and root privilege
is checked before this code is reached. However, it's an annoying
bug on the session bus.

Both build systems arrange for this to be the case,

On Windows, it's probably going to be /mingw/share or

This means we handle OOM correctly, and makes it obvious

affect the actual content of the strings.
Instead of redefining DBUS_DATADIR to be a function call
(which hides the fact that DBUS_DATADIR is used),
this patch makes each use explicit: DBUS_DATADIR
is always the #define from configure or cmake, before
