0f56c1ad12 lvmnotify.c: Check to see if dbus daemon is running
The lvm dbus daemon will auto activate on dbus API calls.  To
prevent the dbus daemon starting when lvm command line tools are
being used we will check to see if the daemon is running first.
If the daemon is not running, we will not notify the daemon.

For this check to work it requires the changes done previously
with commit: 3fdf449348

7f97c7ea9a build: Don't generate symlinks in include/ dir
As we start refactoring the code to break dependencies (see doc/refactoring.txt),
I want us to use full paths in the includes (eg, #include "base/data-struct/list.h").
This makes it more obvious when we're breaking abstraction boundaries, eg, including a file in
metadata/ from base/

68d6d342f8 dbus: only log msg as debug if lvm2-lvmdbusd unit missing for D-Bus notification
Do not emit warning message but only log debug message if
lvm2-lvmdbusd.service unit is missing and at the same time
we have global/notify_dbus=1 (which is used by default if we
configured sources with "--enable-notify-dbus"). We don't want
hard dependency between LVM2 and lvmdbusd so it's enough to log
only debug message in this case.

0973d6e331 notify: Fix hang with lvm shell & --enable-notify-dbus
When lvm is compiled with --enable-notify-dbus and a user uses lvm
shell, after they issue 200+ commands the lvm shell will hang for
~30 seconds trying to notify the lvm dbus service that a change
has occurred.  This appears to be caused by resource exhaustion,
because the sockets used for dbus communication are not be closed.

a8319e62c0 vgscan: add --notifydbus to send a notification
This command option can be used to trigger a D-Bus
notification independent of the usual notifications
that are sent from other commands as an effect of
changes to PV/VG/LV state.  If lvm is not built with
dbus notification support or if notify_dbus is disabled
in the config, this command will exit with an error.

2d5dc6512e dbus: add notification from commands
When a command modifies a PV or VG, or changes the
activation state of an LV, it will send a dbus
notification when the command is finished.  This
can be enabled/disabled with a config setting.
