2938c2125e Adapt to API change in AX_CODE_COVERAGE version 28
AX_CODE_COVERAGE recently changed the way it embedded its Makefile rules
in the output file: instead of using @CODE_COVERAGE_RULES@, users
are now meant to include aminclude_static.am.

The new AX_CODE_COVERAGE is only in the latest autoconf-archive release,
version 2019.01.06, which is inconveniently new, so bundle everything
we need for the moment.

This requires us to stop using the deprecated CODE_COVERAGE_LDFLAGS
(which we still used to support older versions of autoconf-archive)
and replace them with CODE_COVERAGE_LIBS.

e23bba929a test: Move dbus-daemon-launch-helper-test here, and rename
The -test suffix does not indicate that this is a test, but rather that
it is for tests (similar to the -unix and -win suffixes on modules like
dbus-sysdeps). This seems unnecessarily confusing, so rename it to end
with -for-tests.

39ea37b587 trivial: Remove trailing whitespace from copyright notices
We don't usually mass-remove trailing whitespace from the actual source
code because it would complicate cherry-picking bug fixes to older
branches, but that reasoning doesn't really apply to the comments
containing copyright and licensing notices.

Removing trailing whitespace makes it much easier to move code around:
we have a commit hook that rejects commits containing trailing
whitespace, but that commit hook counts moving a file as a delete + add
pair, so it objects to moving code that contains trailing whitespace.

0c9f943277 build: Add a way to set CFLAGS for AddressSanitizer etc.
We don't want to set these globally via the normal CFLAGS, because if
we did, AddressSanitizer would catch test-segfault deliberately
segfaulting, and "helpfully" turn it into exit status 1, which in turn
makes our test fail because it asserts that the segfault is reported
as a segfault.

A typical use with gcc as compiler, on a reasonably recent Debian,
would be:

    ./configure SANITIZE_CFLAGS="-fsanitize=address -fsanitize=undefined -fPIE -pie"

This is technically a denial of service because the dbus-daemon will

because all the rejected messages are also very likely to have
been logged to the system log.

94806fb2c7 Don't let dbus-daemon and its subprocesses inherit unnecessary fds
This should avoid test failures under CMake in which the
dbus-daemon inherits an unwanted fd from CMake's test framework, causing
the close-on-exec check before executing activated services to fail.

The dbus-daemon now marks all fds that it inherits, except for its
stdin, stdout and stderr, to be closed on exec. For completeness, the
dbus-daemons run by dbus-run-session and dbus-launch also now inherit
stdin, stdout, stderr and the pipes used to communicate with their
callers, but nothing else.

4b46e9cb0f desktop-file: Treat backslashes in section names as literal
The Desktop Entry Specification doesn't give any special meaning to
backslashes in section names: a line "[\n]" starts a section whose
name is the two characters (backslash, n), not a section whose name
is a newline. GKeyFile in GLib matches this interpretation.

In practice, the only section used by dbus-daemon is "D-BUS Service",
only way this could make a difference is if someone had written it
as "D-BUS\sService". According to
https://codesearch.debian.net/search?q=%5C%5BD-BUS%5C%5CsService%5C%5D
there is no instance of that pattern in Debian.

bus_container_instance_lost_connection() was previously only called
when we failed to set up a connection with a server due to OOM, but
it is now also called (instead of being duplicated) when we are told

To make sure that connections from containers can never cheat their
way into being treated as uncontained, do not set their
contained_data_slot to NULL.

<!DOCTYPE busconfig SYSTEM "http://example.com/bees"> would have been
