eshell: improve the method to group directories first

* eshell-conf.el (em-term, dir-literal, show-recursive, sort-method)
(show-all, show-almost-all, listing-style, human-readable)
(numeric-uid-gid, block-size, reverse-list, show-size, insert-func)
(flush-func, error-func): Just variables that are needed by Eshell
implementation of ls.

(eshell/l): Equivalent with calling `eshell/dl` with "-glah" in front
of arguments.

(durand-eshell-group-entries-by-directory): Obsolete function.

(durand-eshell-ls-dirs-first): A variable that controls whether to
group directories first.

(durand-eshell-ls-sort-entries, eshell-ls-sort-entries): An advice
around the original sorting function, which groups directories into a
separate list, to be sorted before the rest.  This approach respects
the original sorting method, and performs no extra sorting, as opposed
to the previous approach.
