cf91579b8d Inline foreach macro for internal usage 
Avoid calling _next() function because it's an exported function and
linker can not optimize it.

Thanks to "Gustavo Sverzut Barbieri <barbieri@profusion.mobi>" for
suggestion.

69f9dd4369 no more kmod_loaded and kmod_loaded_module. 
kmod_loaded_get_list() now returns a regular list of kmod_modules, use
kmod_module_get_module(), kmod_module_unref() and
kmod_module_unref_list() to operate on it.

f12ae3c438 kmod_module: extended information gathering. 
provide means to get:
 * refcount
 * initstate
 * holders
 * sections

this can be used to individually query properties from modules,
similar to /proc/modules (kmod_loaded / kmod_loaded_module).

d13e606ff6 improve kmod_config api. 
make the function names reflect the structure they are operating on.

the structure is now allocated and remembers the context it was
created, then no need to give the context in every function call.

1ce08a563e improve "const" keyword usage. 
functions that do not modify their parameters get them as const pointers.

special cases:
 * kmod_get_userdata/kmod_set_userdata: return as void* for user convenience.
 * kmod_list_append/kmod_list_prepend: take const void* for user convenience.

7f3eb0cced Add lookup to create modules list from alias 
We return a kmod_list when searching for an alias. Right now, it only
search for aliases in config files.

To use it, we create a list:
	list = NULL;
	kmod_module_new_from_lookup(..., &list);

And iterate over it to get the modules and their details:

	kmod_list_foreach(l, list) {
		struct kmod_mod *mod = kmod_module_get_module(l);
		...
		... kmod_module_get_name(mod);
		... kmod_module_get_path(mod);
	}

Aliases might contain globs and are match by using fnmatch().
