* lisp/ox-latex.el: New variable `org-latex-language-alist'
(org-latex-language-alist): Unify in a single list `org-latex-polyglossia-language-alist' and `org-latex-babel-language-alist', and make the two variables obsolete. However, it may be convenient in the future to replace this list with a more robust one. (See: https://list.orgmode.org/taeb0a$r62$1@ciao.gmane.io) (org-latex-guess-babel-language): This function has been modified so that the new Babel command `babelprovide' is also recognized. This command is necessary to load the languages served by Babel exclusively through an ini file. Therefore, the new Babel syntax is supported alongside the old one. Note that languages that are served exclusively via an ini file are not added to the Babel argument.
