boardd: article{stat,part,head,tail} keys.

Cache key is a key that can be used to check if the file is edit by user.
Currently, "<st_dev>-<st_ino>" is used for approximation.
Each method operates content in file described by <offset> and <length>.
The function of methods is described as below:
part - output the desired part of file.
head - select a good portion from the beginning of the part.
(eg. end with a new-line; not inside a DBCS char)
tail - select a good portion from the end of the part.
Note that <offset> and <length> correspond to the original file,
not to be confused with conversions. (eg. UTF-8)
