Patch for dot-files sort order under glibc 2.2

[Dmitry Yu. Bolkhovityanov]

    Hi!

    I worked out a patch (very tiny BTW -- thanks to good style of MC
sources) which fixes the problem.

    The idea is trivial -- "ad" and "bd" flags change from boolean to
integers (they are integers anyway, because of "bd-ad"), and "ISDIR" gets
bigger weight than "is-dot-file".

    The patch is against mc-4.5.54.

    I'm crossposting it to mc-devel (sorry if it isn't needed).

    As to case mixing in name sort, there is a "FIXME" note just before
#define string_sortcomp, so somebody obviously realized the problem before,
but yet with no solution.
