This is more or less a temporary fix to restore the former behaviour. In
the long term objects will define a max value, which will be of use for
all kinds of meters.
-d was broken because fork-to-background was done after the update thread creation, so the
threads ended up in the wrong process. This delays the thread creation until after the fork.
Create each thread upon registration of the callback function, then use
semaphores to signal when it's time to update and when updating is
finished.
Many thanks to pavelo who originally came up with the idea for this.
There are no INFO_* variables any more, so the argument passed to OBJ()
is always a function pointer or zero. By checking the argument passed in
add_update_callback(), the branch in the OBJ() macro can be dropped,
too.
* Remove leftover INFO_* values from object definitions which didn't
trigger anything.
* Drop the whole INFO_* enum as it's values are not used anymore.
* Drop all need_mask alterations (no idea why there were here at all,
but surely not sane since they are missing in the non-linux
functions).
* Drop the update delay for update_meminfo(), as parsing /proc should
not lead to abnormal overhead.
* Check for x_initialised from inside update_x11info(), so we can call
it unconditionally.
Besides improving performance when updating stuff, we ideally have no
text object specific code in update_stuff() anymore (aside some
leftovers).
The macros in construct_text_object() have gotten a bit crazier than
they were before:
* using CALLBACK(&func) instead of an INFO_* parameter to OBJ() will
make it add the given callback to the list of callbacks to be iterated
over at each update interval.
* BEWARE: the above assumes function pointer values to be > 0!
* This implicitly fixes a bug in the code: passing 0 as INFO_* value
led to selecting INFO_MAIL (1 << 0 == 1).
* Now it would select INFO_CPU (== 0), which got unused and therefore is
not a problem at all (the 0 value should be unused in enums anyway).
This needs some more work, then we should be able to drop the whole
INFO_* enum. Then CALLBACK() can die again and with it goes the ugly
casting stuff done to distinguish callbacks from INFO_* values.
All ERR()'s are renamed to NORM_ERR() and box to mbox so that they don't
clash with things in ncurses.h .
Ncurses is enabled by default when building conky but can be disabled with
--disable-ncurses .
At the moment configure doesn't check if ncurses is actually available.
I'm adding support for ncurses so that we can make as much things as possible
that are only available in X11 also available in console in the future.
Added support for X alignment across multi-lined objects (i.e., using
$alignr with $exec). This may be a bit buggy. Disabled OpenMP code
until GCC's implementation stabilizes (it's causing too many problems).
A couple Lua API changes.
I moved the weather stuff into its own thread, and also fixed up some
abuse of <simplelist> formatting throughout the docs. Hopefully we can
keep things a little more uniform from now on.
If the first for-loop succedds in finding the desired interface, it will return to its caller. The only way we drop to the second for-loop is if nothing is found thus far, so no need to check for (i == 16).

Moved interface_up(...) from linux.{c.h} to common.{c,h} and taught it
to check for ENXIO as well to make it work on FreeBSD.

Instead of using a hardcoded maximum number of slots for
stats of different disks, use a linked list. Also since the algorithm to
update each device's counters is the same for updating the totals, share
equal code, which in my eyes not only saves a bunch of LoC, but also
drastically increases readability.
Since there is no choice of which moc player to get information from,
all moc objects' data source can be identical. Also hide some internal
data (the thread e.g.). Since from now on there can only be one moc
thread (not highlander ;), we don't need to treat the thread object
specially.
While here, fix indenting.
Handle mpd internal information inside mpd.c. Use a refcounter to check
if the mpd-information can be freed (maybe useless). Remove the now
useless "full" flag of free_text_objects.
