storage/posix: Implement .unlink directory
Problem: For EC volume, If a file descriptor is open and
file has been unlinked, any further write on that fd will
fail. When a write request comes, EC internally reads some
blocks using anonymous fd. This read will fail as the file
has already been unlinked.
Solution: To solve this issue, we are using .unlink directory
to keep track of unlinked file. If a file is to be unlinked
while its fd is open, move this to .unlink directory and unlink
it from .glusterfs and real path. Once all the fd will be closed,
remove this entry form .unlink directory.
