Really all we need from this file is a way to get xkb_component_names
from an xkb_rule_names, which is now the only thing being exposed. This
should allow for some much needed refactoring of this code.
Since this is only used by xkbcomp.c and uses xkbcomp functions, also
move rules.{c,h} under the xkbcomp dir.

i.e. xkb_map_new_from_file. The reason is that flex only works with
FILE's, so we must use fdopen on the file descriptor; but to avoid a
memory leak, we must also fclose() it, which, in turn, closes the file
descriptor itself.
Either way is not acceptable, so we can either:
* dup() the fd and use fdopen on that, or
* have the user call fdopen on his own, and accept a FILE* instead of an
fd.
The second one seems better, and is standard C, so why not. We must add
stdio.h to xkbcommon.h though, which is regrettable, but not a big deal.

xkb_state_ref was missing.
Also modify the _ref functions to return the object instead of being

struct my_object my_object_new(struct xkb_state *state)

my_object->state = xkb_state_ref(state);
[...]
}
Essentially "taking" a reference, such that you don't forget to
increment it and it's one line less (see example in our own code).
