This patch introduces an Interface HandleReadDirer, which implements ReadDir to read partial sub-dirents accroding to request offset and size. From now on, readdir could be implemented in two ways: * ReaddirAll reads all sub-dirents one time * Readdir reads partial sub-dirents and the caller needs to call it multple times if more sub-dirents are requested * If both are implemented, Readdir is used Signed-off-by: Sheng Yong <shengyong2021@gmail.com>

This implements ReadDir for fuse. In order to save current position of readdir, a map DirContexts is introduced in `Dir struct'. Key Value pair (fuse.HandleID, DirContext) is created and saved in DirContexts when readdir starts, and is removed when parent directory is closed. ReadDir reads a number of dirents from current position, thus a DirContext, based on ReadDirLimit. After that, a new position is saved in the same DirContext.

This patchset introduces HandleReadDirer for fuse. It allows readdir
to only read partial sub-dirents one time. If both HandleReadDirer
and HandleReadDirAll are implemented, the former is used.
