Provides united way of parsing kernel module path
into several components.

The new kmod_path__parse function and few defines:

  int __kmod_path__parse(struct kmod_path *m, const char *path,
                         bool alloc_name, bool alloc_ext);

  #define kmod_path__parse(__m, __p)      __kmod_path__parse(__m, __p, false, false)
  #define kmod_path__parse_name(__m, __p) __kmod_path__parse(__m, __p, true , false)
  #define kmod_path__parse_ext(__m, __p)  __kmod_path__parse(__m, __p, false, true)

parse kernel module @path and updates @m argument like:

  @comp - true if @path contains supported compression suffix,
          false otherwise
  @kmod - true if @path contains '.ko' suffix in right position,
          false otherwise
  @name - if (@alloc_name && @kmod) is true, it contains strdup-ed base name
          of the kernel module without suffixes, otherwise strudup-ed
          base name of @path
  @ext  - if (@alloc_ext && @comp) is true, it contains strdup-ed string
          the compression suffix

It returns 0 if there's no strdup error, -ENOMEM otherwise.
