Takuya Fujiwara 34318aedf4 Add prolog swipl linter (#1979)
* add prolog/swipl linter

* use load_files/2 instead of read_term/2

Because it also checks some semantic warnings / errors
not only syntactic warnings / errors.

e.g.:
* singleton warning
* discontiguous warning
* ...

cf. http://www.swi-prolog.org/pldoc/doc_for?object=style_check/1

* support error messages with no line number

    :- module(module_name, [pred/0]).

causes

    ERROR: Exported procedure module_name:pred/0 is not defined

* add test for prolog/swipl handler

* cosmetic fixes

* detect timeout using SIGALRM

* rename g:prolog_swipl_goals to g:prolog_swipl_load

* write doc for prolog/swipl linter

* update toc and README

* fix ignore patterns
