Add new file completion tables, change project.el to allow using them

* lisp/file-complete-root-relative.el: New file.

* lisp/uniquify-files.el: New file.

* test/lisp/progmodes/uniquify-files-resources/: New directory
containing files for testing uniquify-files.

* test/lisp/progmodes/uniquify-files-test.el: New file; test
uniquify-files.

* lisp/files.el (path-files): New function; useful with new completion
tables.

* lisp/progmodes/project.el (project-file-completion-table): Use
file-complete-root-relative completion table.
(project-find-file): Add optional FILENAME parameter.
(project--completing-read-strict): Rewrite to just use the given
completion table; extracting the common directory is now done by
file-complete-root-relative. This also allows using the new
uniquify-files completion table.

* lisp/minibuffer.el (completion-category-defaults): Add
uniquify-file.
(completing-read-default): Add final step to call completion table
with 'alist action if supported.
