The reload handling for activation simply dropped all knowledge
of pending activations, which was clearly wrong. Refactor things
so that reload only reloads directories, server address etc.
Based on a patch originally from Matthias Clasen <mclasen@redhat.com>
(Commit message written by Colin Walters <walters@verbum.org>)
A current Fedora goal is to convert projects to libcap-ng which
more easily allows dropping Linux capabilities. For software
which also links to libdbus, it's problematic to link against
libcap as well.
Though really, libdbus should have never linked against libcap
in the first place, which is another thing this patch changes
by moving the libcap-using bits out of dbus/ and into bus/.

A variety of system components have migrated from legacy init into DBus
service activation. Many of these system components "daemonize", which
involves forking. The DBus activation system treated an exit as an
activation failure, assuming that the child process which grabbed the
DBus name didn't run first.
While we're in here, also differentiate in this code path between the
servicehelper (system) versus direct activation (session) paths. In
the session activation path our error message mentioned a helper
process which was confusing, since none was involved.
Based on a patch and debugging research from Ray Strode <rstrode@redhat.com>
In practice, ay seems to be used mostly for binary data (in which case,
hex output is fine) or for Unix file paths (because they may be
non-UTF-8) and similar human-readable strings. So let's print the latter
similarly to strings.
Previously dbus_message_iter_get_arg_type() was called twice: once in
the loop condition to update 'current_type', and once to check if the
loop will run again. This patch moves updating current_type to the end
of the loop body.
The timeout handling code subtracts the elapsed time from the timeout
each time a message is received, which drastically reduces the timeout
in circumstances such as service activation.
Correct so that the timeout is never modified, and the elapsed time
instead subtracted where necessary.

libdbus-convenience may use system libraries, but not the other way
round. Most platforms don't care, but on some platforms this means that
system libraries need to be listed after libdbus-convenience.la on the
link line.
The current SIGINT handling of dbus-monitor ain't making too many people
happy since it defers the exit to the next msg received -- which might
be quite some time away often enough.
This patch replaces the SIGINT handling by simply enabling line-buffered
IO for STDOUT so that even if you redirect dbus-monitor into a file no
lines get accidently lost and the effect of C-c is still immediate.
halfline came up with the great idea to use setvbuf here instead of
fflush()ing after each printf().
(Oh and the old signal handler was broken anyway, the flag should have
been of type sigatomic_t and be marked volatile)

This is a temporary hack for systems which use DBUS_BINDIR=/bin,
but then move dbus-launch back into /usr/bin. Longer term,
we should explicitly support this in upstream code, or even better
figure out how to move dbus-launch into /bin (e.g. dynamically
load libX11 if available), or have a --with-x11-tools configure
option.

The basic idea with this bug is that we effectively ignore errors
on write. Only when we're done reading from a connection do we
close down a connection. This avoids a race condition where
if a process (such as dbus-send) exited while we still had
data to read in the buffer, we'd miss that data.

Split out the process-launching code, which can be reused for

(cherry picked from commit 6b163e95e7)
On some platforms such as MacOS X and Windows, we can't depend
on an environment variable to determine the address of the
session bus. Create a sysdep function dbus_lookup_session_address
which can be filled in with platform-specific code.

Locking a message has the side-effect of updating the message's length
header. Previously, if dbus_message_marshal() was called on an unlocked
message, it could yield an invalid message (as discovered by Ben
Schwartz in <http://bugs.freedesktop.org/show_bug.cgi?id=19723>).
