Gnus: Improve subthread sorting;
make subthread sorting customizable and add docs for it * doc/misc/gnus.texi (Sorting the Summary Buffer): Document new defcustom `gnus-subthread-sort-functions' and remove the obsolete documentation of `gnus-sort-threads-recursively'. * lisp/gnus/gnus-sum.el (gnus-subthread-sort-functions): New defcustom. (gnus-sort-threads-recursively): Delete defcustom. (gnus-sort-threads-recursive): Adapt accordingly. * lisp/gnus/gnus-sum.el (gnus-sort-subthreads-recursive): New function. (gnus-sort-threads-recursive): Use it. (gnus-sort-threads): Unconditionally call `gnus-sort-threads-recursive' again. Now that determines how to sort subthreads.
