readdir: add dirent index array
...
This removes the risk of corrupted data being sent back to the kernel
should it use the offset from one opendir-readdir in another. In this case
it would at most skip dirents.
According to the standards the offset is only valid when used within
the opendir -> releasedir but NFS uses offsets across independent
calls.

remove .fuse_hidden file creation
...
addresses #521
mergerfs is written using libfuse's high level API. The HLAPI forces a certain
behavior with regard to unlinking or rename overwriting of open files. It
renames the file to .fuse_hiddenXXXXXX and when incoming requests refer
to the unlinked file it will use path based calls and use that path.
This behavior leads to rmdirs failing or some software noticing
the .fuse_hidden files.
This patch changes the HLAPI and removes entirely the .fuse_hidden behavior.
See the README for more.
