fuse: add store request
Userspace filesystem can request data to be stored in the inode's
mapping. This request is synchronous and has no reply. If the write
to the fuse device returns an error then the store request was not
fully completed (but may have updated some pages).
If the stored data overflows the current file size, then the size is
extended, similarly to a write(2) on the filesystem.
Pages which have been completely stored are marked uptodate.
