The reason of making it fixed size is that I was just lazy
and didn't expect that decoder/encoder were called so
frequently.  :-( The reaons of 0x4000 was that most of the
elisp files in lisp/language were less than 0x4000
characters.

And, yes, we can estimate the actually necessarey
CHARBUF_SIZE as coding->src_bytes on decoding, and
coding->src_chars on encoding.

By the way, perhaps the most effective way for making
ENCODE_FILE faster and less memory-touching is to change
encode_file_name return FNAME when FNAME contains ASCII
only or file-name-coding-system is utf-8.
