Do not have a ->name char * field, but a char[32] instead. This isn't a
big problem, the longest color in /etc/X11/rgb.txt is 23 chars long, and
if it becomes a problem one day, one could just strip the name and
generate an hexadecimal representation on the fly instead. But allocating
the name is asking for a lot of trouble.
Since we do not allocate anything anymore, just don't allocate anything
anymore at all, it avoids the mess of xcolor_copy/_wipe and fixes a lot of
sleeping bugs (p_dup were used e.g., which is wrong).
Pass xcolor_t *, xcolor_t becomes too big to be passed by value. Add
consts at some places.
xcolor_new allocates nothing, hence is renamed xcolor_init, has xcolor_t
as a first argument (OO-style, this is self), and doesn't touch the
structure at all if it returns false, which allow us to skip a lot of
intermediates values.

Note that it's undefined to have side effects on an argument and pass this
argument again to another function.

This makes the code way more readable, and also avoids a lot of strcmps.
Use it for draw_align_get_from_str as a proof of concept.

Make area_t smaller so that it fits in an uint64_t using 4 {u,}int16_t's
for it. Note that xcb uses the very same structure, so we aren't loosing
any information while remaining very small.
This is better to use arrays in term of:
* memory access when iterating over area_t's;
* allocation because area_t's have no *next/*prev members anymore, which
makes it a tiny structure (8 octets);
* allocation because we allocate area_t's by vector of'em rather than one
by one.

For that matter, use elements as a filter for elements we care about, and
let the hook implement whatever it needs without duplicating everything.
The resulting algorithm is still O(n²) where n is the number of filtered
elements (3 at most right now), which isn't bad if we don't need to get
too many elements, but at least it's not quadratic in the number of
attributes anymore.
Speedup improvements could be done using gperf btw.

We have a stack, don't be ashamed to use it.
Instead of:
foo_t *foo;
foo = foo_new();
/* work with foo */
foo_delete(&foo);
It's way better to:
foo_t foo;
foo_init(&foo);
/* work with &foo */
foo_wipe(&foo);
Remember: more mallocs == more fragmentation.
