Log:
Do not rely on behaviour undefined by ANSI C, use thunks to adapt
alphasort-like interface to the comparision function required by
qsort() and qsort_r().
For opendir() thunk and alphasort(), comment on why we deviated from
POSIX by using strcmp() instead of strcoll().

Thanks.
FreeBSD (wollman) fixed the corresponding undefined behaviour (which was
inherited from 4.4BSD) in fts's comparison function in 2002. fts uses
extra indirections and mostly-wasted space instead of qsort_r().
