titdic-cnv.el: Bring all definitions under the `tit-` namespace

Add a `tit-` or `tit--` prefix where necessary.  Adjust all callers.
I kept the old names via obsolete aliases for now, although it's probably not
worth the trouble.

* lisp/international/titdic-cnv.el: Bring all definitions under the
`tit-` namespace.
(tit-quail-cxterm-package-ext-info): Rename var from
`quail-cxterm-package-ext-info`.  Adjust value to new names.
(tit-dic-convert): Rename from `titdic-convert`.
(batch-tit-dic-convert): Rename from `batch-titdic-convert`.
(tit-quail-misc-package-ext-info): Rename var from
`quail-misc-package-ext-info`.  Adjust value to new names.
(tit--tsang-quick-converter): Rename from `tsang-quick-converter`.
(tit--tsang-b5-converter): Rename from `tsang-b5-converter`.
(tit--quick-b5-converter): Rename from `quick-b5-converter`.
(tit--tsang-cns-converter): Rename from `tsang-cns-converter`.
(tit--quick-cns-converter): Rename from `quick-cns-converter`.
(tit--py-converter): Rename from `py-converter`.
(tit--ziranma-converter): Rename from `ziranma-converter`.
(tit--ctlau-converter): Rename from `ctlau-converter`.
(tit--ctlau-gb-converter): Rename from `ctlau-gb-converter`.
(tit--ctlau-b5-converter): Rename from `ctlau-b5-converter`.
(tit-miscdic-convert): Rename from `miscdic-convert`.
(batch-tit-miscdic-convert): Rename from `batch-miscdic-convert`.
(tit-pinyin-convert): Rename from `pinyin-convert`.

* leim/Makefile.in (${leimdir}/quail/%.el, misc_convert)
(${srcdir}/../lisp/language/pinyin.el): Use the new names.
