s3: OneFS bulk directory enumeration support
OneFS provides the bulk directory enumeration syscall readdirplus(). This
syscall has the same semantics as the NFSv3 READDIRPLUS command, returning
a batch of directory entries with prefetched stat information via one
syscall.
This commit wraps the readdirplus() call in the existing POSIX
readdir/seekdir VFS interface. By default a batch of 128 directory entries
are optimistically read from the kernel into a global cache, and fed to
iterative calls of VFS_OP_READDIR.
The global buffers could be avoided in the future by hanging connection
specific buffers off the conn struct.
Added new parameter "onefs:use readdirplus" which toggles usage of this
code on or off.
