This adds support for reading log entries from the Systemd journal. A
new command, called simply 'journal', is added which takes a number of
lines as a parameter and optionally which journal (user or system) to
read from.
Obviously, libsystemd is required to build journal support. Tested on
Arch Linux (Systemd v229).

When parsing the argument string for graph objects, check if there is a
double-quoted command in the beginning of the string and extract it
before parsing any options. This prevents items in a command from being
improperly recognized as graph options. It should also eliminate the
need to place commands with spaces into a separate script.
Also, fall back on default_graph_{height,width} instead of using
hard-coded values so that the default values set in a user's config will
work.
The main purpose of this commit is to ensure that exec callbacks are
registered at startup (or config reload), so that they have a chance to
run on the first update interval. Much of the code in exec.cc got
consolidated, making it easier to follow. Several checks for NULL
pointers should eliminate some obscure segfaults I noticed, as well.
During the refactoring, I implemented height and width arguments for
execbar and execgauge. The functionality was already there, but wasn't
being used. All this is accompanied by updates to the man page and
plenty of code comments.
Adds mpd_albumartist support as an object since mpd_artist lists all participating artists of the
current song and not the main album artist.
patch by Sébastien Lavoie-Courchesne
I removed the code for automatic killing of stuck children, because (by admission of the person
who wrote it) it wasn't working. I also removed the $pre_exec variable, because one can use lua
to generate the config on the startup, if one wants to.
the way it is implemented now just wont work with the new config file. And i don't think that
many people used it anyway. Maybe add a replacement later?
Warning: Altough the current version works (for me),
the syntax of the configoptions and vars will probably change
over time. Contact me if you have ideas.
The following is a example of how you can use it now:
mysql_host someserver.com
mysql_db my_database
mysql_user loginname
mysql_password "s3cr3t"
TEXT
${mysql select var1 from some_table}${mysql select var2 from some_table}
I've added $memwithbuffers to complement $mem, $memeasyfree, etc. This
variable indicates the used system memory, regardless of buffers/caches. If
the "no_buffers" option is set to "no", it will be the same as $mem. The
reason I find this change useful is that I like to display both the total
used system memory and the memory being used by applications.
I've also included a memwithbuffersbar, which is the same as membar except
that it uses $memwithbuffers as the size instead of $mem.
