Clean up how we arrange for environ to be declared
Annoyingly, the POSIX way to declare environ (as
"extern char **environ") is a redundant declaration in glibc with
_GNU_SOURCE; work around that.
We also have a workaround for _NSGetEnviron() needing to be used
instead of direct access to environ in at least some circumstances on
Mac OS. Attempt to sync that up between all the files that use environ,
consistently sorting the most special special-cases first (Windows
for files that are compiled there, then Mac, then GNU, with
lowest-common-denominator POSIX last).
The affected files are already OS-specific, so I'm not bothering to
introduce a nicer or higher-level API for this.
Based on the best bits of an earlier patch from me, and an earlier
patch from Thomas Zimmermann.

Linux: use readdir(), not deprecated readdir_r()
glibc >= 2.24 marks readdir_r() as deprecated. It is meant to be a

Be more const-correct
As a general design principle, strings that we aren't going to modify
should usually be const. When compiling with -Wwrite-strings, quoted
string constants are of type "const char *", causing compiler warnings
when they are assigned to char * variables.
Unfortunately, we need to add casts in a few places:
* _dbus_list_append(), _dbus_test_oom_handling() and similar generic
"user-data" APIs take a void *, not a const void *, so we have
to cast
* For historical reasons the execve() family of functions take a
(char * const *), i.e. a constant pointer to an array of mutable
strings, so again we have to cast
* _dbus_spawn_async_with_babysitter similarly takes a char **,
although we can make it a little more const-correct by making it
take (char * const *) like execve() does
This also incorporates a subsequent patch by Thomas Zimmermann to
put various string constants in static storage, which is a little
more efficient.

dbus_activation_systemd_failure: do not use non-literal format string
In principle this could lead to arbitrary memory overwrite via
a format string attack in the message received from systemd,
resulting in arbitrary code execution.
This is not believed to be an exploitable security vulnerability on the
system bus in practice: it can only be exploited by the owner of the
org.freedesktop.systemd1 bus name, which is restricted to uid 0, so
if systemd is attacker-controlled then the system is already doomed.
Similarly, if a systemd system unit mentioned in the activation failure
message has an attacker-controlled name, then the attacker likely already
has sufficient access to execute arbitrary code as root in any case.
However, prior to dbus 1.8.16 and 1.9.10, due to a missing check for
systemd's identity, unprivileged processes could forge activation
failure messages which would have gone through this code path.
We thought at the time that this was a denial of service vulnerability
(CVE-2015-0245); this bug means that it was in fact potentially an
arbitrary code execution vulnerability.

additionally, it would log to stderr, unless the process is dbus-daemon

This is the desired behaviour because when we hook up

This patch implements test-coverage statistics with the autoconf macro

Run 'configure' with '--enable-code-coverage' to enable support for

dbus-daemon, dbus-launch: cope with callers having closed standard fds
In Debian bug <https://bugs.debian.org/829348>, lightdm appears to
have been starting dbus-launch with at least one of the three
standard fds 0, 1, 2 (stdin, stdout, stderr) closed. This resulted
in the dbus-daemon's epoll_create1() returning a fd less than 3.
Later, _dbus_become_daemon() replaces fds 0-2 with /dev/null. As a
result, a subsequent call to _dbus_loop_add_watch() for the reload
pipe resulted in calling epoll_ctl on the non-epoll fd pointing to
/dev/null, which fails with EINVAL, resulting in the dbus-daemon
exiting unsuccessfully.
Unix programs are not normally expected to behave correctly when
launched with the standard fds not already open; but at the same time,
X11 autolaunching means that dbus-launch (and hence the dbus-daemon)
can get started from an arbitrarily precarious situation.

_dbus_ensure_standard_fds: new function to ensure std* fds are open
This function opens stdin, stdout, stderr pointing to /dev/null
if they aren't already open. Optionally, it can also replace
whatever is available on those fds with /dev/null.
To allow for use in contexts where only async-signal-safe functions
should be used, such as between fork() and a following exec(),
this function does not use conventional libdbus error handling
(which would require malloc). Instead, it sets errno and returns
an explanatory string.
