Spelling fixes, mostly UK→US

* lisp/custom.el (custom--sort-vars-1):
* lisp/language/indonesian.el:
Use ‘dependent’ rather than British spelling in internal names.
In indonesian.el, the ‘-ant’ spelling was incorrect even for UK
spelling as it was an adjective not a noun.
* lisp/emacs-lisp/package-vc.el (package-vc--clone):
Fix typo in spelling of README-elpa file name.
* lisp/vc/vc.el (vc-revert):
Use American instead of British spelling in diagnostics.
* m4/texinfo.m4 (gl_TEXINFO_INDEXING_IS_LOCALE_DEPENDENT):
Rename from gl_TEXINFO_INDEXING_IS_LOCALE_DEPENDANT.  Use changed.
