Streamline xcolor_t.
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.
