Make pinyin to Chinese character mapping available to elisp

* leim/Makefile.in: Build the file pinyin.el from pinyin.map.
* lisp/international/titdic-cnv.el (pinyin-convert): New function that
  writes the library pinyin.el, containing a new constant
  `pinyin-character-map'.
* .gitignore: Ignore the generated pinyin.el file.
