f90f6325b9 Avoid out-of-bounds write in graph_append function 
Retrieve graph only when s->graph is already allocated, which also mens
that the s->graph_width is bigger than 0, and thus avoid out-of-bounds
write in graph_append function.

Prior to 594d0c85ba ("Fix bug of "Graph reset when using conditional
color"") s->graph was not (re)allocated when s->graph_width and
s->graph_allocated were equal to zero, therefore, s->graph stayed equal
to nullptr. This effectively meant that graph_append function returned
immediately after call and did nothing.

This behavior changed with introduction of std::map<int, double *> graphs,
because its retrieve_graph support function allocates s->graph even for
s->graph_width equal to 0. Then, subsequent call of graph_append can
continue and the first element of the graph is set later in this
function in line:

  graph->graph[0] = f; /* add new data */

causing out-of-bounds write, as there is not enough space in array of
zero length. This write messes up internal data of memory allocator (at
least in musl libc case) and the application later segfaults in attempt
to free this memory in store_graph function.

Fixes: 594d0c85ba ("Fix bug of "Graph reset when using conditional color"")

da2ddb00ed Partially revert change from c352069b31. 
It's not quite clear to me what the intent was here, but I don't believe
this change was correct. We shouldn't block on callbacks within the main
loop.

This fixes #901.

23a4936835 Add a legacymem variable for free compat. 
It seems there is some confusion between the way Conky reports free
memory, versus other programs. I'm adding a new variable, `legacymem`,
to provide the same value that is reported on older programs that don't
report memory the way recommended by newer kernels.

For more details, see:
 * https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=34e431b0ae398fc54ea69ff85ec700722c9da773

 * https://github.com/brndnmtthws/conky/pull/1028
 * https://github.com/brndnmtthws/conky/issues/1090

This resolves #1090.

Roll back change from 91a3f2ed87. 
While made in earnest, I think this change was incorrect and actually
caused a regression.

Thanks to ChrisCheney for communicating this in a way that my small ape
brain could understand.

This resolves issue #1090.
